Introduction
Biomass fired water tube steam generator is horizontal type double drums water tube generator with high steam quality, the combustion equipment is chain grate. This generator takes several breakthroughs on generator design, such as membrane water cooling wall, low thermal inertia design, and water cooling combustion chamber. This biomass fired steam generator adopts fast assembly or packaged assembly structure, generator with steam capacity lower than 4t/h is fast assembly water tube structure, generator with steam capacity between 6~25t/h is consisted of upper part (heated part) and lower part (combustion equipment). The biomass steam generator has reached the international advanced level on technology and performance, it has the advantages of compact structure, high steam quality, sufficient output, operate convenient and environmental protection.




Biomass fired water tube steam generator is wide adaptability of different biomass fuels, such as wood pellet, bagasse, straw, rice husk, coconut shell, cotton seeds, corncob, peanut shell, waste cloth, etc. To avoid coking and improve combustion efficiency, adopts unique double secondary air design, to improve conditions of biomass fuel. 



Characteristics of Chain Grate


1) The small scale chain grate could resist the temperature as high as 1200℃, long working life.

2) The chain grate has a low biomass fuel leakage because of the small gap.
3) Mechanized feed, high automatic degree, decrease labor cost.
4) Convenient for maintenance, it could be done without boiler shut down.
5) Based on customers’ requirement and fuel characteristics, the grate could be designed as reciprocal grate.

Products Advantages
1. High Quality Assurance

1) There is a professional design engineer team, before manufacturing, every generator design drawing have to be approved by boiler and pressure vessel experts of CSBTS ( State Bureau of Quality Technical Supervision ), and then the boiler could be produced only if qualified.
2) To ensure the raw materials quality, all the steel plates are special-used for boiler with the Inspection Certificates. The raw material materials are inspected when entering factory, and only the qualified material could be put in storage and used for production.
3) To ensure the welding quality, there a professional welding team, including more than 30 senior welders. The welding materials are stored under constant temperature and humidity, to ensure the welding material quality.
4) The welding quality will be further examined during boiler manufacturing, by using x-ray detection, ultrasonic flaw detection, magnetic test, or penetration test, etc.
5) To ensure the boiler quality, the leakproofness and strength of pressure parts will be tested. The hydrostatic test is done to make sure there are no water drop or water mist leakage appear on steal wall or welding joint, no water leakage appear at the place of expansion, and no obvious residual deformation and abnormal situation.
6) To ensure no problems before boiler delivery, all the raw materials and boilers are supervised and inspected by the experts of Inspection Institution for Boiler and Pressure Vessel. There are international uality certificates of ISO 9001 and CE, we can also offer the inspection report of SGS, BV, etc., Quality Certificates, Energy audit report, and Energy Efficiency Test Report, etc.
2. Safety Assurance

3. High Efficiency Assurance

4. Professional Installation and After-sale Team
1) Professional engineer installation team offer the door to door installation and after sale service. The steam generator will operate smoothly and safety, and you will get them without worries.
2) 24 hours hot-line to solve your problems, and offer the professional technical supports and after sale service in time to all over the world.
5. Convenient Maintenance
1) The chain grate is convenient for maintenance, it could be done without generator shut down.
2) There are manhole, head hole, and special hand hole on the biomass fired steam generator, convenient for generator internal installation, inspection and clean.
Combustion Process

The front generator body is arranged around with water cooled wall, the upper part is connected with upper drum, the downpart is connected with header, to consist the combustion chamber. To absorb the furnace radiant heat sufficiently, there is intensive convection tube bundle between the upper drum and lower drum.
The straw fuel drops down at the front of grate from fuel hopper, move with the chain grate, after preheat dry distillation, combustion, and burnout, the slag fall into slag hopper, and then removed outside the steam generator. The high temperature smoke gas flow through the convection heating surface, economizer, dust remover in order, and finally discharged into the atmosphere by induced draft fan through chimney.
