Technology — SEAPOWER

Flame Size Dictates Structure Size. Boiler size is directly related to the size of the combustion flame. Our exclusive technology produces micron-sized coal particles so fine they burn similar to heavy fuel oil in small compact boilers. A comparable pulverized coal boiler can be as much as five times larger than a micronized coal .

Pulverized coal boiler - coal powder boiler, coal fired boiler

Pulverized coal boiler is a kind of industrial boiler or power plant boiler that produces thermal energy by burning pulverized coal. Coal is ground to the size of a fine grain, mixed with air and burned in the flue gas flow. It is also known as pulverized coal furnace, powdered coal boiler or coal powder boiler.
