Chain grate coal fired steam boilers take coal as fuel to heat water to steam. This chain grate realize the coal automatic feeding and slag automatic remove. Because of the low labour strength, the chain grate steam boiler has been the most popular coal boiler in industry. Romiter chain grate coal fired steam boiler uses high quality tube plate, currugated tube to make sure hgh thermal efficiency higher and sufficient steam capacity
Advantage Feature
- Advanced Structure: Boiler is single drum-type quick assembly three pass fire and water tube boiler, with large heating surface and high thermal efficiency;
- Compact design: Boiler has advantages of compact structure, the reasonable water cycle design, and quick start;
- Advanced chain grate: The advanced chain grates assure reliable operating, less coal missing and energy-saving also reduce installation and maintenance workload of the grate; using a long arch, increasing the effective area of grate, good coal adaptability and fuel burning fully;
- High efficiency: Grate with reasonable combustion air distributor makes fuel burning fully and improves machine efficiency;
- Pure steam: steam dryness degree of 96% or more;
- High intelligent control: The boilers have the pressure, temperature, water and other multi-chain security control; a high degree of mechanization, simple and convenient operating;
- Easy to install: China grate boilers are transported in integrated form from factory. This makes the installation period very short.
