Small Capacity Package Boiler

K25 type package boiler refers to a small capacity fast install boiler, of which most parts would been pre-assembled at workshop. Boiler is supplied in large components, site work will be simple.

K25 Boiler

The Design Principle of K25 boiler is to reduce the work complexity and workload at customer site as much as possible, and to achieve commissioning in the shortest time. Both pressure part and non-pressure part will be pre-assembled at workshop. Helps customer save cost and time. Boiler is designed to be middle temperature middle pressure (3.82MPa, 450°C), B-MCR is 25tph. Forward running chain grate is applied as combustion system. Crushed Palm shell, Palm fiber, EFB, and bulk, root, bagasse and other biomass could be used as fuel. In the worst case, coal could be mixed into fuel to help combustion of wet biomass. In order to reduce corrosion caused by Chloridion Cl¯ which is rich in biomass fuel, special steel is applied on boiler HT and LT area.
