High Efficency Coal Steam Boiler and Industrial Biomass Boiler For Chemicals Factory with Natural Circulation
The coal steam boiler produced by the company are equipped with water-cooling equipment on both sides, and a re-bar pipe is installed inside the drum, and a figure-shaped flue is arranged. The combustion equipment uses a light chain grate that can be frequency-controlled. The control system has all implemented the automation mode. The equipment has the characteristics of stable operation, safety and energy saving.
Coal Steam Boiler Features
1. The coal/wood fired boiler produced by the company is a square box type assembled forced
circulation chain grate boiler. The biomass fired steam boiler is lined up from the upper body and the lower furnace and can be
assembled quickly at the user's site of use.
2. The travelling grate boiler body has a square coiled tube on the heating surface, and coal steam boiler structure is a serpentine convection heat exchange tube. This
structure is suitable for single furnaces and double furnaces.
3. According to the waste heat usage of the equipment, air
preheater, steam waste heat equipment and hot water economizer are
arranged at the tail of the boiler for waste heat recovery. This
structure can effectively reduce the exhaust gas temperature,
improve the boiler heat efficiency and reduce fuel consumption.
4. According to the fuel characteristics, the industrial biomass boiler convection heat exchange section adopts measures such as high and
low misalignment, widening of the spacing and arrangement of soot
blowing devices. This structure can reduce coal steam boiler ash and improve boiler thermal efficiency.
5. The coal/wood fired boiler body is made of high-quality insulation materials and special
construction technology, and the insulation effect is good.
6. The industrial biomass boiler is heated surface processing using a fully automatic gas shielded
welding process, and X-ray inspection of all solder joints. Ensure
that the welding quality is stable and reliable.
7. Large-scale coal fired boilers are equipped with partial integration and on-site assembly. This
type of integration is very high, and on-site installation is quick
and easy.
