Sitong - Model DZL1 - Solid Fuel Fired Steam Boiler
From Biomass Fired Boiler
Solid fuel fired chain grate boiler is single drum water tube and fire tube boiler, combustion equipment is chain grate. Water wall tubes at left and right sides of furnace are the radiated heating area. the two wings at furnace and screw fire tube in the drum are convection heating area. This boiler uses the upper drum, water wall tube and head are in symmetrical arrangement mode. The drum is welded assembly by cylinder and front back tube plate. This furnace structure is in reasonable arrangement and high efficiency, also, it adopts unique double secondary air design to improve the high combustion efficiency. The solid fuel fired steam boiler uses the new scientific achievement, such as arch tube plate, screw fire tube to solve the problem of tube plate flaw, water wall tube explosion, low efficiency, insufficient output, poor adaptability of coal, improve the heat transfer.

Characteristics
- The small scale chain grate boiler could resist the temperature as high as 1200℃, long working life.
- The chain grate has a low coal leakage because of the small gap.
- High automatic degree, decrease labor cost.
- Convenient for maintenance, it could be done without boiler shut down.
- Based on customers’ requirement and fuel characteristics, the grate could be designed as reciprocal grate.
Advantages
- There is a professional design engineer team, before manufacturing, every boiler design drawing have to be approved by boiler and pressure vessel experts of CSBTS ( State Bureau of Quality Technical Supervision ), and then the boiler could be produced only if qualified.
- To ensure the raw materials quality, all the steel plates are special-used for boiler with the Inspection Certificates. The raw material materials are inspected when entering factory, and only the qualified material could be put in storage and used for production.
- To ensure the welding quality, there a professional welding team, including more than 30 senior welders. The welding materials are stored under constant temperature and humidity, to ensure the welding material quality.
- The welding quality will be further examined during boiler manufacturing, by using x-ray detection, ultrasonic flaw detection, magnetic test, or penetration test, etc.
- To ensure the boiler quality, the leakproofness and strength of pressure parts will be tested. The hydrostatic test is done to make sure there are no water drop or water mist leakage appear on steal wall or welding joint, no water leakage appear at the place of expansion, and no obvious residual deformation and abnormal situation.
- To ensure no problems before boiler delivery, all the raw materials and boilers are supervised and inspected by the experts of Inspection Institution for Boiler and Pressure Vessel. There are international uality certificates of ISO 9001 and CE, we can also offer the inspection report of SGS, BV, etc., Quality Certificates, Energy audit report, and Energy Efficiency Test Report, etc.2.
