Abstract

The invention discloses a method and device for reducing carbon monoxide emission of a gas water heater. The method includes the steps that external wind pressure data detected by a wind pressure detection device are received; when the external wind pressure is larger than the preset wind pressure threshold value, the rotating speed of a draught fan of the gas water heater is increased, and the opening and closing angle of a primary air inlet baffle of the water heater is increased; a controller receives the CO content value detected by a CO sensor arranged in a smoke tube in the gas water heater; when it is detected that the CO content value is higher than the preset content threshold value, the rotating speed of the draught fan of the water heater is increased continuously, the opening and closing angle of the primary air inlet baffle of the gas water heater is increased, and then the CO content value is detected till the detected CO content value is equal to or lower than the presetcontent threshold value or till the rotating speed of the draught fan is the maximum and the primary air inlet baffle is opened to the maximum degree. By means of the method and device, the problem of increasing of the CO content in bad conditions is solved, the CO content of the water heater in the normal use condition is reduced, and the heat efficiency in the bad conditions is improved.

Description

technical field [0001] The invention relates to gas water heaters, in particular to a method and device for reducing carbon monoxide emissions from gas water heaters. Background technique [0002] Most of the existing gas water heater flue gas carbon monoxide (CO) content is within 600PPM, which is under normal combustion conditions. The content is almost in a state of geometric progression, which will seriously pollute the environment, and will make the internal combustion conditions of the water heater combustion system worse, reduce the thermal efficiency of the water heater, damage the water heater, and reduce the service life of the whole machine. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method and device for reducing carbon monoxide emissions from gas-fired water heaters, which solves the problem of increased CO content under harsh conditions, solves the CO content of water heaters under normal use...
