DZL series coal/biomass fired steam boiler realizes almost zero pollution with the use of special dust collector solution (bag dust collector, double towers desulfurization, etc.). This series boiler is single drum horizontal type shell boiler, the combustion equipment is chain grate (small scale flaker is available), has the advantages of feed mechanically and strong adaptability of different fuels. The fuel could be II class bituminous coal, the diameter should be 6-25mm, and ash content should be less than 32.4%. Otherwise, DZL series boiler could also burn biomass fuel, including wood, straw, bagasse, rice husk, coconut shell, cotton seeds, peanut shell, etc.
Biomass Fired Boiler Burning process
Fuel falls from coal hopper onto the front of chain grate, moves along with the chain grate and will be preheated, dried, ignited, burned out. Slag will be discharged by slag remover(eliminator) at any time. Herring bone arch is adopted to improve igniting condition. Smoke forms between front and back arches vortex, completely mix with air, burns out and then goes after each other through smoke flue at two wings, front smoke box, threaded smoke tubes, cast iron economizer(for hot water boiler no cast iron economizer), dust remover, draft fan and will be emitted through chimney |

FAQ of steam boiler
Q1: How to get the best price quickly?
1) Please offer the boiler capacity & pressure you need, and the fuel you plan to use, then we could offer the suitable boiler model.
2) Please provide your name, email address, WhatsApp/WeChat/Skype, and company name, then we will send the best price and boiler details immediately.
Q2:What are the difference between DZL and SZL with the same capacity?
DZL
1. Usually for the boiler with capacity lower than 10Ton
2. Easy for transportation
3. Lower request on water quality
4. Low boiler room construction charges
5. Low requirement on water quality
SZL
1. Usually suitable for bigger capacity boiler
2. Good water circulation, small water volume
3. Warm up faster, higher steam quality
4. Higher request on water quality
5. Higher thermal efficiency
Q3: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.
Q4:How long it takes for boiler installation and debugging?
The boiler is easy to install, it could be finished within 2 weeks, we have the professional abroad installation team to help for installation. Moreover, our technicians offer after-sale service every quarter in many countries, like Philipines, Bangladesh, Indonesia, Pakistan.
