Chain grate 15 ton/hr steam boilers burning coal and biomass
1.15 ton coal and biomass steam boiler adopts widthwise layout double drums structure, which totally overcomes the phenomenon of bulge by directly beating the drum in the furnace. The layout of the heating surface is more reasonable.
2. The tow sides of furnace adopt membrane water wall structure which can ensure the seal ability of the furnace and higher the boiler efficiency as well.
3. The arch adopts water cool structure, which can improve both the rigidly and the reliability of the arch, and the service life is extended.
4.The grate boiler adopts GEF’s improved appreciative slag removal technology.
5. In the heating surface of the boiler convection bank and the economizer, there are junctions of dust blower reserved. To some special material, necessary measures can be adopted, to avoid the corresponding problems.
6.The chain grate boiler adopts double sides wind feed, separate air chambers, which can meet the requirements of the combustion of the fuel efficiently.
7.The boiler adopts double layers or single layer layout structure, which can meet the customers’ requirements better.
