Problems solved by technology

The efficiency of the boiler mainly depends on the structure of the heating chamber and the heating area. Most of the heating chambers of the existing boilers adopt a tubular heating structure. Due to the low heat transfer coefficient of the tubular heating structure and the high exhaust gas temperature, it is impossible to control the flue gas. Condensation of medium water vapor, so boiler efficiency is very low

Embodiment Construction

[0009] In the figure, the air intake fan 1 sucks in air through the air inlet 2, and the gas entering with the gas inlet 3 forms a mixed gas in the air and gas premixing chamber 4. The mixed gas is sprayed evenly through the gas distributor 5, and then further stabilized by the gas pressure stabilizing plate 6. The pressure-stabilized mixed gas is discharged through the surface of the porous metal combustion plate 7 and ignited on the surface of the porous metal combustion plate. The ignited mixed gas burns in the combustion chamber 8, and generates a large amount of heat after the mixed gas burns to form high-temperature flue gas. The high-temperature flue gas enters the flue gas-water plate heat exchanger 9 from the smoke-water plate heat exchanger, and enters the smoke-water plate heat exchanger 11. In the smoke-water plate heat exchanger, the high-temperature flue gas exchanges heat with water, and the temperature of the high-temperature flue gas drops , the temperature o...

Abstract

The invention relates to a plate-type gas combustion condensing water boiler using gas as fuel. A burner of the boiler is a plate-type gas burner instead of an original flame burner. A combustion chamber of the boiler is in a smoke-water plate-type heat exchange structure, instead of an original tubular heat exchanger, and the function of condensing steam in smoke is improved for low-temperature water. The plate-type gas burner and a smoke-water plate-type heat exchanger are disposed in the boiler, and heat efficiency of the boiler can be greatly improved. The plate-type gas combustion condensing water boiler is mainly used to produce normal-pressure normal-temperature hot water, heating, living and process hot waters for buildings and the like.

Description

technical field [0001] The invention relates to a plate type gas burning condensing hot water boiler. This plate type gas combustion condensing hot water boiler uses gas as fuel, and the burner of the boiler uses a plate type gas burner to replace the original flame type burner. The heating chamber of the boiler adopts a smoke-water plate heat exchange structure to replace the tube heat exchanger of the original boiler to improve the condensation effect of low-temperature water on the water vapor in the flue gas. Since the boiler is equipped with a plate gas burner and a smoke-water plate heat exchanger, the thermal efficiency of the boiler can be greatly improved. This plate type gas combustion condensing hot water boiler mainly produces hot water at normal pressure and normal temperature, which is used for heating of buildings, domestic and process hot water, etc. Background technique [0002] At present, traditional gas-fired hot water boilers are composed of three majo...
