wood biomass boilers 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.
Wood-fuelled heating systems, also called biomass systems, burn wood pellets, chips or logs to provide warmth in a single room or to power central heating and hot water boilers. A stove burns logs or pellets to heat a single room - and may be fitted with a back boiler to provide water heating as well.
Tarm Biomass sells indoor wood boilers. Indoor boilers can be located in detached buildings outside of the primary heated space, but they are not weatherized like outdoor boilers or outdoor wood furnaces. Indoor boilers generally provide better heating performance, as heat losses from the appliance and pipes go to the home rather than outdoors.
Hurst Boiler & Welding Co., Inc manufactures its biomass boiler systems with an extended burn chamber, increasing dwell time for the combustion of any unwanted particulates and emissions before they are able to exit the system, making the process much cleaner, which reduces maintenance time and costs.
Biomass Boilers for large projects Heizomat has been building high quality boilers in Bavaria since 1983. Heizomat boilers come in a wide range of sizes and burn a variety of biomass fuels, from pellets to wood chips, to other difficult fuels such as chopped straw, miscanthus, and switchgrass.
Biomass boilers could benefit from the Renewable Heat Incentive (RHI) which may recoup some of the installation costs.. According to the Energy Saving Trust, an automatically fed pellet boiler costs between £9,000 and £21,000, including installation.
Hurst Boiler & Welding Company, Inc. has been manufacturing, designing, engineering and servicing gas, oil, coal, solid waste, wood, biomass and hybrid fuel-fired steam and hot water boilers since 1967, for thousands of satisfied customers.
In comparison to oil or gas fuel, the wood fuel will need significantly more storage space. Wood pellets, wood chips, and logs are the most common types of wood fuel used in biomass boilers. Wood chips and pellets are more suitable for automatic systems because logs have to be manually put into the boiler by a human.
