1,High efficiency heat transfer element ---Threaded pipe→the boiler thermal efficiency is 6%-8%higher than the national→save energy ,high thermal efficiency
2,Arched tube plate→high temperature tube plate cracking(NO)→safety
Advanced pressing process→Tube sheet cracking(NO)
Boiler bottom free of flame radiation→bottom of boiler shell swelling(NO)
Reasonable water circulation loop,unique return water injection device →water wall tube explosion(NO)
Automatic welding is adopted in the main welding seam→Increase lifespan of boiler
3,Chain-grate→frequency control →Operation is stable and reliable
the domestic advanced chain grate→less coal leakage,save energy ,reduce the workload of installation and maintenance of the grate
4,Optimized furnace arch → burning effect is good
5,Burning water supply automatic control→reduce the labor intensity of fireman
6 ,Three layer thermal insulation technology→improve the thermal efficiency of the furnace

1,What are the spare parts for coal/biomass fired boiler?
Generally, the spare parts are instrumentation valve, grate plate, gasket, etc.
2,What are the advantaged for coal/biomass fired boiler
(1).Usually for the boiler with capacity lower than 10Ton
(2).Easy for transportation
(3).Lower request on water quantity
(4).Low boiler room construction charges
(5).Low requirement on water quality
3,What are the differences between vertical type boiler and horizontal type boiler with the same capacity?
A (1).Structure of vertical boiler is compact, occupy a limited area.
(2).Convenient on installation and removal.
(3).Low cost and investment on capital construction. Steam exhausted fast and sufficient.
B(1).The combustion space of horizontal is big, fuel can be burned completed.
(2).The thermal efficiency is higher than the vertical boiler,
(3).Horizontal type: less thermal loss, stronger output, and higher steam quality.
4,What are the tube seat at the top of steam boiler?
Pressure gauge - safety valves (two) - main steam valve - auxiliary valve - water inlet
5,How long can the coal/biomass fired boiler works?
Coal/biomass boilers could work for 10~15 years, under correct operation, high water and coal quality, etc.
6,How to avoid collapse of bricks, and what should be done if it happened?
When boiler installation finished, drying the boiler according to the manual, it's very important to avoid collapse of bricks.
