HOT WATER BOILER USING COKES AS FUEL

摘要

PURPOSE: A hot water boiler is provided to rapidly raise the temperature of water, to maximize the thermal efficiency, and to reduce the fuel cost by applying a heat of cokes to the hot water boiler. CONSTITUTION: An outer wall(21) of a combustion chamber is provided with a lower hot water tank(3) and an insulation member(2) so as to endure against the ultra-high temperature. A bottom member(19) allows ash to move into an ash collecting box(10). A hole(4) is provided to allow mixing gas of oil and air to flow into the combustion chamber. Hot water flows from an inlet(14) to an outlet(15) through an electric pipe(18) and a connection pipe(12). The lower hot water tank(3) is also installed at a wall of the combustion chamber(8) so as to effectively heat water. The lower hot water tank is connected to an upper hot water tank through a hot water passage(7).
