1. Features of SZL series double drum industrial coal boiler
1).This series boiler belong to double drums water tube boilers, designed for blowdown on surface and the quality of steam is pretty good.
2).Steam boiler is devided into saturated steam boiler and overheat steam boiler and meet the needs in seperated.
3). Boiler main body and grate adopt large parts for ex-factory, short installation time and low charge for installation.
4). boiler capacity of 4-35T / H (2.8-29MW).
2. Advantages of our production and service
1),100%safety, running stably, excellent water level and pressure control, fully automatic operation 
 2),Boiler running life > 20years.
 3),Good after-sale service. It is free for you to get the damaged spares in warranty period(1 year) if there is any questions. Assure that we can supply you spares in boiler's all life. 
 4), We can arrange engineer to your company for installation and commissioning and training. If you need us at any time, we can send our technicians and prepare in a short time.
 5), Special paint is used after assembly. Paint is particularly used in your climate area, which is anti-corrosion, anti-abrasion and color-fastness.
3. Factory assurance:
1).One year parts warranty
2). Spare parts available at ex-factory price
3).Different voltage available
4).100% tested before delivery
