straw biomass power plant is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
Technical advantages Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
How much biomass will you need to burn every year for the power plant to run at full capacity? We will use around 250 kilotons every year at full capacity. We are working with the Worldwide Farming Partnership to deliver a proportion of this straw and are also looking to work together with producers locally and regionally where this is appropriate.

The power station was constructed between 1998 and 2000 by FLS Miljo and is operated by EPR Ely Ltd. It generates 270 GWh of electricity from 200,000 tonnes of biomass annually, supplied by Anglian Straw Ltd. Straw is the major fuel of the plant, but oilseed rape and the energy crop Miscanthus are also used, as well as some natural gas.
Straw is a natural, renewable resource.The efficient supply of energy based on the renewable resource straw. A concept to install a heat and power plant for a sustainable heat & power generation by using the renewable resources straw.In addition to this ecological benefit there are several other advantages using straw in comparison to the ...
The model assumes that rice straw was not dedicated to power but is residues food cultivation. Therefore CO 2 emissions due to cultivation and harvesting are neglected. It has been assumed that the maximum distance to transport the rice straw from the farm gate to the power plant is 75 mi.
Highlights This article has presented a comprehensive supply chain analysis for the rice straw-fueled power generation in Thailand. The appropriate formula and considerations are presented in detail to model the supply chain of a biomass-based power plant. The costs breakdown of the logistics operations are discussed thoroughly for two baling systems. The consumption and cost of diesel fuel ...
