Coal burning For process steam

Chain grate boiler Capacity from 5t/h to 30t/h, and pressure from 1.25Mpa to 2.5Mpa (12.5bar to 25bar) are standard.Thermal efficiency of 79% to 82% is expected.

Advantages: short lead time, easy operation, robust construction, easy to maintain, low in price, less demand in civil work.

Dis-advantages: low thermal efficiency, coal quality required (less than 3% sulfur, minimum LHV for coal@4500Kcal/kg), So2 emission require external equipment. Maximum pressure is 2.5Mpa(25bar), super-heated steam temperature 450C (maximum)

Applications: process steam or hot water.
