A steam combustion-supporting boiler

Abstract

The invention discloses a steam combustion-supporting boiler. The steam combustion-supporting boiler comprises a boiler and a pressure balance valve, wherein the boiler is provided with a water cavity and a hearth; a water tank is arranged outside the boiler; the hearth is provided with a steam generation device; the steam generation device comprises a heating pipe, a steam drum and a steam spray pipe; the pressure balance valve comprises a valve body and a valve core; the valve body is provided with a valve body cavity; the left end of the valve body is provided with a steam joint, and the right end of the valve body is provided with a threaded joint; the steam joint is communicated with a space above the water surface in the cavity of the water tank; a valve core is arranged in the valve body cavity; the valve body is provided with a water inlet and a water outlet; the valve core is a shaft which is provided with an annular groove; a pressure adjusting bolt and a pressure adjusting spring are arranged in the threaded joint; a cooling water pipe is arranged in the space above the water surface of the cavity of the water tank in a penetrating manner; a water inlet end of the cooling water pipe is communicated with the lower end of the water cavity through the pressure balance valve, and a water outlet end of the cooling water pipe is communicated with the upper end of the water cavity. According to the steam combustion-supporting boiler, the steam pressure of the steam drum is kept at constant pressure, so that the combustion of the boiler is kept in a stable state, the time and the labor are saved, and the boiler is convenient to use.

Description

technical field [0001] The invention relates to a boiler, in particular to a steam combustion-supporting boiler. Background technique [0002] The existing steam combustion-supporting boiler is a boiler that can inject water vapor to the furnace fuel for combustion support. The boiler is equipped with a water chamber and a furnace. The heated water in the boiler water chamber enters the external radiator, and the cooled water The water then enters the boiler water cavity for heating, so that the water in the water cavity is continuously heated and dissipated by circulation. The furnace is equipped with a steam generating device, and a water tank is installed outside the boiler. The water tank provides water source for the steam generating device. The steam generating device includes a heating tube, a steam bag and a steam spray pipe, the heating pipe is connected with the steam bag, the steam bag is connected with the space above the water surface of the inner cavity of the ...
