Title:
BURNER, WALL-MOUNTED BOILER AND TEMPERATURE RISE CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/233117
Kind Code:
A1
Abstract:
A burner, a wall-mounted boiler using same and a temperature rise control method therefor. The burner comprises a support; a first accommodating cavity used for placing fire rows (3) and a second accommodating cavity (12) through which gas flows are provided on the support; one end of the second accommodating cavity (12) is provided with an intake pipe joint (4); several nozzles (5) that are arranged in parallel to each other are provided on the second accommodating cavity (12); gas that is ejected by means of the nozzles (5) enters the first accommodating cavity for burning; a stopping block (6) divides the second accommodating cavity (12) into a ventilation portion and a non-ventilation portion; the stopping block (6) can move relative to the second accommodating cavity (12); in the ventilation portion, gas enters the nozzles (5); in the ventilation portion, the number of nozzles (5) into which gas is introduced is adjusted by adjusting the distance of the stopping block (6) relative to the intake pipe joint (4). When it is not needed to obtain hot water having a high temperature, the stopping block (6) is controlled to move close to the direction of the intake pipe joint (4), and the number of nozzles (5) into which gas is introduced is decreased; when it is needed to obtain hot water having the high temperature, the stopping block (6) is controlled to move away from the intake pipe joint (4), and the number of nozzles (5) into which gas is introduced is also increased, thereby achieving precise adjustment and control of the number of nozzles (5) used for burning.
