Chain Grate Boiler
Yuanda Company manufacture Steam boiler & Hot water boiler & Thermal oil boiler & Hot air generator.
Hot Selling: DZL series chain grate boiler & SZLseries chain grate boiler
Introduce DZL Chain Grate Boiler
DZ series chain grate coal/biomass fired boiler, it is horizontal three-pass water & fire tube boilers with chain grate combustion device. Threaded pyrotechnic tubes are arranged in the drum to form a convection heating surface, while the drum and the water walls on both sides from a radiation heating surface in the furnace.
Comsbution Device options: Chain grate, Reciprocating grate, Fixed grate, Travelling grate.
Boiler Structure Features
1. Smoke and dust separator chamber
Separate smoke and dust according to inertia,reduce the original effluent concentration of soot.
2. Optimized design CAD
Choose the best furnace from dozens of options,improve economical efficiency.
3. Convex tube plate
1) Improve tube plate flexibility, so as to reduce the heating stress of welded sew at the pipe end.
2) Prevent tube plate cracking, cancel bracing,simplify the structure.
4. Large size of simple circulation loop drop pipe and lower set box
Increase the flow rate of water on water cooling wall in order to prevent subcooled boiling. To prevent pipe explosion,Increase the reliability of water cycle
5. New pattern of furnace arch
Strengthen the combustion, could burn kinds of fuel: wood, coal and biomass, improve combustion efficiency.
Introduce SZL Water Tube Chain Grate Boiler
SZL series water tube coal/biomass fired boiler, is double drums offset furnace structure ("D" type or "A" type), membrane water wall panel structure, with Chain Grate or Reciprocating Grate Stoker. Boiler with advantages of high technology, environmental and energy saving.
Combustion stokers: Chain Grate, Reciprocating Grate
Boiler Structure Features
1. High-efficiency water-tube structure
SZL and SZW series boilers adopt a water-tube design with a large heating surface, providing efficient heat transfer, rapid steam generation, and stable operation.
2. Optimized furnace and combustion system
The spacious furnace provides sufficient combustion space and residence time, promoting complete biomass combustion, improving fuel utilization, and reducing unburned fuel loss.
3. Reliable and durable construction
The membrane water-wall structure provides good sealing and reduces heat loss. The boiler is designed for continuous industrial operation with high structural strength and long service life.
4. Lower fuel and operating costs
High combustion efficiency and good heat-transfer performance help reduce biomass consumption and operating costs, making SZL/SZW boilers an economical solution for industries with abundant biomass fuel.
The total project cost depends on boiler capacity, fuel type, working pressure, automation level, auxiliary equipment, installation requirements and local regulations.
