Lancaster Farming Uses Blue Flame Stoker (Now known as Triple Green Flame)
Because of the high cost of petroleum-based fuels and the future shortage of fossil fuels, alternate fuel sources continue to be investigated. We know about corn ethanol, solar and wind energy, and have heard about biomass and other terms. But, have you heard about energy produced from poultry litter?

One of the largest costs of operation is heating. Triple Green Flame Stoker has developed some of the industry’s best design solutions to lower heating costs. Our design team can assist you in determining which system is right for your greenhouse operation and budget. Pictures
The use of biomass (primarily wood chips, wood pellets, MSW or agricultural residue) for Industrial application is becoming very popular. Primarily it is used to replace fossil fuels with the use of biomass. Many companies across Canada and the USA have chosen to embrace Triple Green Flame Stoker™ technology to lower their operating costs and reduce their impact on the environment.
This project was set out to demonstrate the viability of linking up the central hot water biomass boiler system with number of existing buildings in the centre of a college. The system design called for the construction of a central biomass boiler plant in a carefully selected location, chosen for good access for biomass fuel deliveries, while minimizing the costs of hot water piping distribution.

TGE Series Main System Components
- Bale magazine (baled straw conveying system to automatically support gasifier with fuel)
- Straw disintegration component (straw shredder and shredded fuel conveyor system)
- Primary combustion chamber (includes the ash removal system, grate system and air distribution system)
- Secondary combustion chamber (includes the silicone/potassium removal tray)
- Hot water heat exchanger (includes automatic cleaning system and clean-out removal tray)
- Exhaust system (the main blower controls air flow and exhausts clean vapour)
- Main computerized control system (combines all necessary electrical devices to control each function with limited supervision)
Baled wheat straw can be stored outdoors or indoors. Indoor storage protects the fuel from precipitation (and often from freezing) and can eliminate varying moisture content and decay in the fuel supply.
Received fuel is moved onto the bale magazine by either a front-end loader or a specially designed automated crane system. The bale magazine can be designed to handle any amount of fuel desired. The magazine automatically feeds baled straw into the disintegration machine as fuel is required for processing.
The fuel processing begins in the shredder where the straw is disintegrated into smaller, manageable particles. Interruptions or delays in reclaiming fuel can occur because of undesirable fuel properties (i.e. poor flow, compaction, frozen chunks, oversized material or contaminants), so fuel preparation is critical to the operation of the entire system.
From the shredder, the particulate fuel is moved by a belt conveyor or auger to the fuel injection system. The fuel injection system feeds the fuel into the primary combustion chamber utilizing a mechanical plunger or twin augers.
The back flow of combustion flames and gases through the fuel entry is controlled by an automated fire door.
Primary Combustion Chamber
The primary combustion chamber is an enclosed area where drying, pyrolysing and oxidizing occurs. The fixed rotating grate supports the fire bed and allows for underfire air to be blown up through the fuel. Effective oxygen supply and control is critical to ensure complete gasification without complete combustion.
Ash collects below the grate and is removed automatically by an auger. In general, ash from biofuel burning is not considered a hazardous waste and can be placed in local landfills. However, most ash is an excellent soil additive and will be of interest to local gardeners and farmers. Proper ash management is critical, as non-combustible inorganic (mineral) content of biomass can become significant, depending on the type of fuel utilized. Inherent ash is generally low in clean wood (0.5%), higher in bark (3.5%) and significant in annual crops such as straw (6.2%), but usually consistent within a fuel type. Ash content is usually expressed on a dry basis, i.e. the weight of ash as a percentage of the total moisture-free fuel weight.
Secondary Combustion Chamber
The hot exhaust gases exit at the top of the primary combustion chamber and pass through a refractory duct into the secondary combustion chamber. Oxygen is added
Where agricultural-based straw is the primary bio-fuel, silica and potassium debris settles in the removable tray at the bottom of the secondary combustion chamber. This requires
The extremely hot gases from the secondary chamber flow to the heat exchanger which is a fire-tube boiler. A hydronic system delivers this heat to desired locations and supply precise heat for any public, commercial, residential or agricultural building. Fly ash can be moved by combustion gas flow and can deposit on the heat exchange surfaces in the boiler. This ash is removed regularly to maintain good heat transfer performance. Tube cleaners are in place to automatically clean the boiler tubes and collect the fly ash in the particulate collection system.
An induced-draft exhaust system completes the combustion process. The induced-draft system uses a large blower located in front of the stack which sucks the exhaust gases out of the boiler and forces them up the stack. The draft of this fan is regulated in relation to the combustion air to maintain a very slight negative pressure in the combustion chambers so that gas flow is continuous and that no combustion gas leaks occur.
Instrumentation is important for efficient operation in response to energy demand and safety. The complete feed and gasification process requires a complex control system using computers and micro-processors to match heat delivery with demand. A key task of the control system is determining the rate at which fuel and air are fed to the primary combustion chamber to ensure gasification, and the rate at which air is fed into the secondary chamber of ensure efficient combustion. Control is achieved when fuel and air are automatically modulated simultaneously to maintain the correct ratio under high or low demand. Start-up and shutdown sequences are programmed, and alarms will sound in upset conditions.
- Electrical power (3 phase system preferred, single phase possible) lAir requirement (compressor 100-120 PSI, 7-10 CSF)
- Cold water source (50-70 PSI, 2-4 gallons/minute)
- Concrete floor and building structure (brick or metal)
- Shelter (or building structure) to cover the disintegration and conveyor system
- Ash bin (to contain ashes being removed from the gasifier primary chamber)
The Triple Green Energy heating system requires little maintenance and management. Tasks such as ash disposal, general cleanup (usually in the fuel storage and handling area), checking heat exchanger water levels, checking the fuel delivery system for oversized material build-up, plus monitoring primary and secondary combustion chamber temperatures, along with stack temperature are done daily. The computer system will signal the operator in upset conditions or for out-of-range readings.
In addition, there are regular maintenance tasks that need to be carried out periodically. These include:
- replenish depleted fuel supply
- lubricate mechanical components
- inspect and adjust chains, gearboxes, blowers, etc.
- remove silica from secondary chamber
- remove debris from heat exchange
- inspect refractory and repair as necessary
- test safety devices
Most of the routine maintenance can be carried out by the system operator or by the general on-site maintenance staff. It is recommended that the system be inspected by a Triple Green Energy service technician annually.
System Life Expectancy
Triple Green Energy systems can last indefinitely, since the components will be replaced as they wear out or deteriorate. In the forest industry, wood combustion systems have been in operation for over 50 years. In practice, 15 to 20 years is used as a reasonable life expectancy for a biomass combustion system in life-cycle costing.
Dillon Consulting Limited was retained by TripleGreenEnergy to conduct source testing on the gasifier exhaust stack to quantify combustion gas emissions. These tests were conducted on our 3 million btu/hr gasifier operating at the maximum system designed production rate of approximately 500 pounds (227 kg) of straw feed stock per hour.
The following gases were measured from the exhaust gas stream:
- Carbon Monoxide
- Sulphur Dioxide
- Oxides of Nitrogen
- Carbon Dioxide
The following table summarizes the results of the combustion gas concentrations in the TGE3000 gasifier exhaust stream.
Combustion Gas concentrations are the average concentrations from 3 separate test periods.
|POI Summary for 24-hr Averaging Period|
|Contaminant||Max POI Concentrations (ug/m3 Property Line/off property||Prov. Of Manitoba Ambient Air Quality Objectives Max. acceptable level (ug/m )3|
|Oxides of Nitrogen||143||59.6||400||200|
“The results of the dispersion model indicate that the emissions of all of the measured parameters from the TGE3000 Gasifier comply with the Ontario and Manitoba regulated Point of Impingement and Ambient Air Quality Criteria Concentrations. The POI concentrations for the remaining combustion gases do not exceed any of the regulated POI limits or AAQC. In general the POI concentrations predicted by the dispersion modeling for all measured pollutants are at least one-half of the regulated levels with no pollution control devices.” – Dillon Final Report, March 2003

A valued by-product from our TGE Series of BioHeat systems
Along with bags of potting soil, mulch, and compost, you soon may see bags of biochar for sale at your local nursery.
To explain what biochar is, we need to return to the Amazon basin circa 450 a.d. Indigenous people didn’t practice slash-and-burn farming as they do now. They practiced slash-and-char agriculture, roasting wood and leafy greens in “smothered” fires, in which lower temperatures and oxygen levels resulted in the production of charcoal instead of ash. The charcoal was buried in fields where crops were grown.
But then, with the arrival of Europeans and their diseases, the Amazon civilizations, some with cities of more than 100,000 people, collapsed. Slash-and-char agriculture was forgotten, as were the fields of buried charcoal. But they weren’t gone. In the 20th century, huge expanses of black soil were rediscovered, although at first no one knew what they were. Then, in the 1990s, scientists determined that these soils were manmade. They were dubbed terra preta (“dark earth” in Portuguese). And they were extensive. Some estimates put the total acreage covered by the charcoal-enriched soil at twice the size of Great Britain.
Most amazingly, the soils extended up to 6 feet deep in many places. Scientists have theorized that terra preta soils are self-propagating and have grown in depth since they were first made. The charcoal, acting a lot like humus, had been colonized by myriad microbes, fungi, earthworms, and other creatures; these soil organisms produced carbon-based molecules that stuck to the charcoal, gradually increasing the soil’s carbon content. Carbon in decomposing plants, which would otherwise escape into the air as greenhouse gases, was sequestered by the biologically active charcoal in the soil. Scientists theorize that the charcoal was originally laid down in thin layers and that earthworms chewed through the layers and mixed them deeply into the soil.
That is just the beginning of the benefits of this strange soil. It appears that the carbon will be sequestered for a thousand—possibly thousands—of years, unable to contribute to global warming in the form of greenhouse gases. Green charcoal, or biochar made from agricultural residues or renewable biomass, appears to hold the most promise as a carbon sink. Every ton of this biochar in the soil is capable of capturing and holding at least 3 tons of carbon.
Biochar also stimulates mycorrhizal fungi—those fungal symbionts that live on plant roots, scour surrounding soil for hard-to-find phosphorus, and deliver it back to their host plants. According to scientists studying the soils, microbial growth of all kinds is substantially improved. And so is the soil’s ability to hold nutrients until plants need them, then dole them out at the optimum rate for plant health. Crops have been shown to grow 45 percent greater biomass on unfertilized terra preta soil versus poor soil fertilized with chemical fertilizers.
Research on biochar is under way at universities around the world, and agribusiness is beginning to show interest. While biochar could be manufactured by cutting down forests and fields, a more sensible approach would be to utilize the billions of tons of organic waste that now goes into landfills—a perfect raw material for biochar.
