High-adjustment-ratio water-cooling premixed combustion high-strength heat exchange gas condensation boiler

Abstract

The invention provides a high-adjustment-ratio water-cooling premixed combustion high-strength heat exchange gas condensation boiler. The high-adjustment-ratio water-cooling premixed combustion high-strength heat exchange gas condensation boiler comprises a combustor and a heat exchanger, wherein the full-premixed combustor mounted in the center of a boiler top plate consists of a booster fan, a premixing chamber and a water-cooling combustion head; a flame stabilizing pipe and an anti-tempering column of the water-cooling combustion head can realize high-adjustment-ratio water-cooling premixed combustion; the heat exchanger consists of a lap of water-cooling wall and one or more laps of fins uniformly arranged in the peripheral direction by bent edge folding fin pipes; an air blower feedsair into the premixing chamber for fully mixing with gas to enter an inner cavity of a hole plate of the combustion head; the air flows out from a fire hole, and is sprayed out from narrow gaps amongthe water-cooling pipes distributed in the peripheral direction; after the air flows out from the flame stabilizing pipe, the air is ignited to uniformly combust in the peripheral direction and the axial direction, and radiates and releases heat to an inner pipe ring; smoke flushes base pipes and fins of inner and outer ring fin pipes in sequence to reinforce heat exchange; and the smoke downwards flows into a dew bearing disc through gaps between a housing and an outer layer fin pipe, and is exhausted into atmosphere from a smoke outlet. The high-adjustment-ratio water-cooling premixed combustion high-strength heat exchange gas condensation boiler is high in combustion load adjustment ratio, compact in heat exchange, low in nitrogen emission and high in heat efficiency.

Description

technical field [0001] The invention relates to the technical field of integral condensing boilers, in particular to a gas-fired condensing boiler with a large adjustment ratio, water-cooled premixed combustion, and high-intensity heat exchange. Background technique [0002] my country is a big country of energy production and consumption. Energy conservation and emission reduction and improvement of energy utilization efficiency are important tasks we face. At the same time, my country's environmental governance still needs to be strictly controlled. The smog problem continues and occurs frequently, and the smog phenomenon in the northern heating season is even worse. for serious. For a long time, my country's energy production and consumption have been dominated by coal. my country's air pollution belongs to the "first generation" soot-type pollution, which is mainly caused by coal combustion. In order to control smog, the heating industry proposes that the clean heating ...
