DZL and SZL, which one is better? Here, the writer wants to say, choose one you need. Purchasing a set of industrial boiler is almost as hard as finding a boyfriend or girlfriend. The one you needs, the one you can trust, the one you should choose. DZL type is with single drum, and firetube boiler. SZL type is with double drums and watertube boiler. Both of them have got IBR and ASME international certifications. Mixed biomass and coal fired cheap dzl single drum horizontal chain grate biomass fired steam boiler capacity is from 4 ton to 75 ton. Dear consumers, you can choose the capacity based on your own factories requirements.
July 26, 2016, Beijing, China Everbright Paper Co., Ltd. and the company signed a "split 6 tons of steam condensing gas cheap dzl single drum horizontal chain grate biomass fired steam boiler contract" by the company responsible for the WNS6-1.25-YQ split condensing gas boiler steam to all production, installation and commissioning work. The product is the use of condensing technology, effective emission of harmful substances SOx, NOx, COx, is industrial boilers efficient and environmentally friendly solutions.
Fluidized bed combustion (FBC) steam boiler for biomass boiler has emerged as a viable alternative and has significant advantages over conventional firing system and offers multiple benefits–compact boiler design, fuel flexibility, higher combustion efficiency and reduced emission of noxious pollutants such as SOx and NOx. The fuels burnt in these boilers include coal, washery rejects, rice husk, bagasse & other agricultural wastes. The 15ton hour coal fired fluidized bed boilers have a wide capacity range- 0.5 T/hr to over 100 T/hr.
This type of boiler is generally preferred in high pressure applications because the high pressure water/steam can be contained within narrow pipes which can contain the pressure with a thinner wall. The thinner wall allows better heat transfer, however can be susceptible to damage by vibration caused by flue gas flow.
