Abstract

The utility model relates to a methane and fire coal double-purpose water heater which comprises an intermediate water jacket furnace body, a cone inner cylinder liner, a methane burner, an inclined air hole, a grate, a coaling opening, and the like. The water heater can utilize methane and save coal, belonging to environmental engineering equipment. The intermediate water jacket furnace body and the cone inner cylinder liner are mutually communicated. A water outlet tube and a water return tube are arranged at the upper part and the lower part on one side of the intermediate water jacket furnace body, while the other side of the intermediate water jacket furnace body is connected with the coaling opening. The methane burner is installed on left and right sides of the lower part of the intermediate water jacket furnace body. The lower part of the methane burner is a boiler cradle. A star-like air inlet is arranged on three sides of the boiler cradle. The cone inner cylinder liner in the furnace body is in V-shaped structure, wherein the lower part thereof is annularly connected with the grate. The inclined air hole is arranged above the grate at the lower part of the cone inner cylinder liner. The inclined air hole is arranged annularly. The hole is inward and upward inclined in strip shape. The methane burner is positioned under the grate and outside the cone inner cylinder liner. A nozzle in the methane burner is provided with a protection cover. The water heater has the main effects of using both methane and fire coal, burning methane instead of fire coal and having high heat exchange efficiency.
