Automatic Coal- Fired Boiler – Providing heat when you need

Our engineers developed an automatic stoker unit equipped with a coal hopper that held enough fuel for several days. This allowed the coal to be cleanly burned and without frequent maintenance. They then saw the need to make a hot water boiler specifically designed to burn coal and built them in multiple sizes to meet our customers' needs.

Biomass Cofiring in Coal-Fired Boilers

Biomass cofiring projects do not reduce a boiler's total energy input requirement. In fact, in a properly implemented cofiring application, the efficiency of the boiler will be the same as it was in the coal-only operation. However, cofiring projects do replace a portion of the non-renewable fuel—coal—with a renewable fuel—biomass.

The use of biogas as an alternative energy is known to be able to reduce GHG emissions by 34.3% because the substitution of fuel wood and LPG is transferred to the use of biogas. This research is expected to be a stimulant and basic data for the realization of low carbon energy conscious villages.

Pulverized coal-fired boiler - Wikipedia

The raw coal is then fed into the pulverizer along with air heated to about 650°F / 340°C from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows the usable fine coal powder out to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.
