Gas boiler

Abstract

The invention discloses a gas boiler, which comprises a gas generating chamber, a gas combustion chamber, an air supply device and a heat exchange device, wherein the gas generating chamber causes incomplete combustion of coal briquettes and has basically closed side walls and top; the gas combustion chamber is communicated with the gas generating chamber; the air supply device supplies combustion-supporting air to the gas generating chamber and the gas combustion chamber; the heat exchange device is used for guiding out the hot air in the gas combustion chamber and performing heat exchange; the gas combustion chamber is arranged at the bottom of the gas generating chamber, and the gas combustion chamber is communicated with the gas generating chamber by a gas passage. Because the gas combustion chamber is arranged at the bottom of the gas generating chamber, when the gas is communicated to the gas combustion chamber by the gas generating chamber, the gas boiler is automatically ignited under the actions of high temperature at the bottom of the gas combustion chamber and the matched air supplied oxygen so as to avoid inconvenience and danger caused by secondary ignition.

Description

technical field [0001] The invention relates to a boiler equipment used for heating and hot water engineering, in particular to a gas boiler. Background technique [0002] After the coal is burned in the producer furnace, the air at the bottom of the furnace is restricted so that the coal cannot be completely burned, thus producing a large amount of carbon monoxide. At this time, the combustible gas discharged from the incomplete combustion of the coal in the producer furnace is called producer gas. . The process of producing producer gas is to first make air pass through the fuel layer, carbon and oxygen react to increase the temperature; then steam and air are mixed through the fuel layer, carbon reacts with steam and oxygen to generate producer gas. At present, most of the boilers that use producer gas as fuel are equipped with a coal-fired furnace to generate gas, and then lead the generated gas through a pipeline to another gas combustion chamber for gas and then ignit...
