biomass fuel boilers - Bing 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.
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.
For over 46 years, Superior Boiler has constructed complete renewable energy systems using biomass as a fuel source. It is Superior Boiler’s philosophy that in order for the United States to reduce its dependency on foreign oil, it must take advantage of its many renewable, natural and …
Biomass technology is environmentally friendly because biomass boilers use renewable resource rather than fossil fuels. Biomass is completely sustainable; the biomass fuel supply can be generated quickly from local agricultural/forestry activity.
Changing the fuel source in some cases can have a negative effect on refractory linings. Using the correct refractory material can help to preserve the integrity of the refractory lining. Biomass boilers utilize solid waste for fuel, which can contain a wide and variable amount of impurities as combustion ash.
Recommendations for improving biomass technology for DHC 3: • Improve efficiency of large biomass boilers (fuel mix, improved control, condensing, higher temperature for electricity production, etc.) • Reduce price of large biomass boilers (materials, rational production of big numbers, etc.) •
Biomass Fuel Is Considered to Be Renewable
Biomass systems are fuelled by wood and burn pellets, chips or logs which can either provide heating in a single room or power central heating and hot water boilers. Biomass boilers generally take up more space than a regular gas or oil boiler and are more suitable for people not connected to mains gas who have space for storage. Recent figures

Some biomass boilers will need a high quality biomass fuel with precisely dimensioned particles and no more than 20% humidity, some other boilers will be able to process fuels with some bigger chunks and humidity up to 35% (for example Säätötuli biomass boilers). Biomass fuel is mostly made with branches, treetops, non commercial trees, hog
The high space requirement compared to conventional fossil fuel boilers can mean that a biomass boiler system will not be preferable to a standard boiler system. Access issues for getting fuel to the boiler system may also rule out some larger properties.
Historically, humans have harnessed biomass-derived energy since the time when people began burning wood fuel. Even in 2019, biomass is the only source of fuel for domestic use in many developing countries. All biomass is biologically-produced matter based in carbon, hydrogen and oxygen.
Biomass needs to be made dense to provide ease of mechanical handling and feeding, uniform combustion in boilers, reduced cost of transportation and ease of storage. The types of dense biomass to choose from are pellets, briquettes or loose biomass that has been dried before being fed into the boiler.
Biomass boilers can replace oil or gas boilers to heat hot water and radiators (or under floor heating). They burn logs, wood chips, wood pellets or other forms of biomass. The most advanced boilers are fully automatic. They control the amount of fuel and air supplied to the combustion chamber.

Profiting from the implementation of energy efficient and sustainable technology will be necessary to maintain a competitive advantage. Hurst Biomass Boiler Systems provide successful strategies and technology which can reduce the operational costs of current facilities and provide an ROI from installation in new construction.
Yet due to the lower heating value, the biomass fuel consumption is more than coal consumption when generating certain amount of steam. Therefore, biomass boilers have higher and larger furnace to ensure the sufficient combustion of biomass fuel as well as full load operation compared with coal fired boiler.
Biomass combustion is a series of chemical reactions by which mainly carbon is oxidized to carbon dioxide, and hydrogen is oxidized to water. However, there are many elements that go into the combustion. Reaction for the combustion of a biomass fuel in air might take the following form, where the first reactant compound is a biomass fuel.
A biomass boiler works in a very similar way to conventional boilers, combusting fuel to produce heat that is then used to heat water. Biomass boilers are normally substantially bigger than their fossil fuel-burning brothers though, for a number of reasons.
Maintenance. Biomass boilers and stoves should be kept clean and swept regularly to remove ash. Ash quantities are generally very low (less than one per cent of fuel volume), but you will still need to empty the ash bin of a wood burning stove or boiler.
In terms of efficiencies advanced pellet boilers can exceed other forms of biomass because of the more stable fuel charataristics. Advanced pellet boilers can even work in condensing mode and cool down combustion gases to 30-40 °C, instead of 120 °C before sent into the flue. Combined heat and power
