reciprocating grate boiler - 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.
The boiler vessel is a two pass hybrid design incorporating a water tubed boiler-type water membrane and a two-pass fire tube scotch marine vessel. The Hybrid RG design is suitable for applications to produce high pressure steam or hot water in ranges from 3,450 - 60,000 lbs/hr (3.4 mm BTU - 60 mm BTU) output from 100 up to 900 PSI.
SHW Reciprocating Grate Boiler. SHW series reciprocating grate boilers combine many patented designs and are leading in the world. It adopts the latest combustion theory product of Xi'an Jiaotong University, could burn different kinds of coal fuel and biomass fuel in a high combustion efficiency.
ZD Grates Stokers Factory( High Military Grates Stokers Manufacturing Co., Ltd) is a professional leading chain grate & reciprocating grate firing system manufacturer in China, supplying boiler companies and garbage waste combustion power plants with our grate stokers,such as chain grates stokers , reciprocating grates stokers, travelling
With rapid development of biomass fuels, in recent years the reciprocating grate furnace industrial boiler has been wide used. Compared with travelling chain grate,the reciprocating grate is better for burning the fuels including rice husk, corn cobs, Nuts, wood chips, palm shells, fibers (EFB) ect.
Main Features of Reciprocating Boiler. Completely combustion: Biomass will be distributed evenly on the grates through reciprocating grate, and the biomass are pushed onto the furnace from the front side of the grate without diversion or narrowing, which make wood chip completely combustion.
Reciprocating Grate Boiler is a kind of biomass boiler, which is suitable for burning biomass fuel like wood dust, straw, bagasse, palm husk, palm fiber, rice husk, etc. In March 2018, customer from an energy company in Ukraine visited our factory to negotiate on biomass power plant boiler.
The firing equipment consists of air-cooled reciprocating grate stoker operated by a hydraulic power pack. It is an inclined step grate consists of alternate stationary and moving rows of grate bar. The grate bar on the Front and middle section is made of high chrome stainless material.

Generally, biomass power plant is operated by many types of boilers such as vibrating grate boiler, stepping grate boiler, reciprocating grate boiler, stationary sloping grate boiler and travelling grate boiler. Bagasse from sugar industry is one of valuable biomass used in power plant and supported as alternative fuel by the government.
Cooperated with HIT, ZBG designed the SHW series reciprocating grate coal fired boiler. A 1 ton/0.7MW boiler can supply heat for over 12,000 square meter floor area. It is a high efficient and energy saving boiler type, now widely applied in pharmaceutical, chemical, food, metallurgical machinery, mining and many other fields and industries.
Grate-firing is one of the main competing technologies in biomass combustion for heat and power production, because it can fire a wide range of fuels of varying moisture content, and requires less fuel preparation and handling.
