Highly energy saving non-smoke corresponding burning type normal pressure hot water boiler

Abstract

A highly energy saving non-smoke corresponding burning type normal pressure hot water boiler comprises an upper boiler body and a lower boiler body; the lower boiler body is provided with a lower boiler body internally-wrapped water jacket and a water pipe grate, and a burning chamber in the lower boiler body is divided into a main burning chamber body and a vice burning chamber body through the water pipe grate from top to bottom; the interior of the upper boiler body is provided with a chimney leading opening, a chimney leading opening externally-wrapped water jacket and a boiler head, an upper boiler body annular flue is arranged in the upper boiler body, internal communicating pipes are arranged between the bottom of the chimney leading opening externally-wrapped water jacket and a disc at the bottom of an upper boiler body internally-wrapped water jacket, and an external communicating pipe is arranged between the top of the upper boiler body internally-wrapped water jacket and the bottom of the lower boiler body internally-wrapped water jacket; a lower boiler body annular flue and lower body flue communicating pipes are arranged in the lower boiler body, and upper boiler body flue communicating pipes are arranged in the upper boiler body. The highly energy saving non-smoke corresponding burning type normal pressure hot water boiler is sufficient in burning, free of smoke, high in heat exchanging efficiency, low in energy consumption and environment-friendly, and suitable for various burning materials, scaling is not prone to occurring, the scaling portion can be cleaned easily, and the service life is long.

Description

technical field [0001] The invention relates to a high-energy-saving smoke-free and dust-free counter-fired normal-pressure hot water boiler, which is suitable for hot water and heating. Background technique [0002] The existing hot water boiler is composed of a furnace body, a water jacket arranged on the inner wall of the furnace body, a combustion chamber and a fire grate arranged at the lower part of the furnace body, and a heat exchange tube connected with the water jacket arranged at the upper part of the furnace body. The principle is The water jacket is heated after the coal added on the grate is burned, and the hot flue gas rises naturally to heat the heat exchange tube and the water jacket. This method is positive combustion, insufficient combustion, large smoke and dust, low thermal efficiency, and high energy consumption; the heat exchange tube is heated by fire-guaranteed tube mode, which is easy to scale on the inner wall of the tube and cannot be cleaned, and...

Problems solved by technology

This method is positive combustion, insufficient combustion, large smoke and dust, low thermal efficiency, and high energy consumption; the heat exchange tube is heated by fire-guaranteed tube mode, which is easy to scale on the inner wall of the tube and cannot be cleaned, and the tube wall becomes thicker, affecting water circulation and reducing thermal efficiency. ; and the thickening of the pipe wall makes the inner diameter of the water pipe shrink to a certain size, which will easily cause the water pipe to burst, causing the boiler to be scrapped, and greatly shortening the service life of the boiler
