Embodiment Construction

[0032] A preferred embodiment of the present invention will now be described with reference to the accompanying drawings. In addition, this embodiment does not limit the technical scope of the present invention, but only illustrates. Components that are the same as in the prior art bear the same reference numerals.

[0033] Fig. 3 is a block diagram of an air-proportional condensing boiler using an air pressure sensor according to the present invention.

[0034] As shown in Figure 3, the air-proportional condensing boiler includes: an air pressure detector 50 installed in the suction chamber 6, which is used to measure the air pressure sucked by the blower 10; an air pressure identifier 51, which uses It is used to convert the air pressure measured by the air pressure detector into an electric signal and output the electric signal; a fuel control electric valve 60, which is used to adjust the amount of fuel to be supplied; a thermistor 52, which is used to detect the circulat...

Abstract

The present invention provides an air-proportional type boiler using air pressure sensor. When the gas supply quantity is fixed and constant rated output is produced, the revolution of air-blower can be regulated so as to make the air supply quantity become constant, so that the air quantity can be supplied according to a certain proportion, and the gas and air can be supplied according to rated output of boiler, so as to can obtain high combustion efficiency.

Description

technical field [0001] The present invention relates to an air proportional boiler using an air pressure sensor, and more particularly, to an air proportional boiler using an air pressure sensor to maintain the rated output of the boiler, in which the number of revolutions of the blower is reasonably adjusted so that at When the gas supply is constant and produces a constant rated output, the air supply volume is kept constant, so that the following problems can be solved: when using the air pressure sensor and the pressure difference to detect the air volume in proportion to control the gas supply volume, so that When it is proportional to the inhaled air supply volume, if the air supply volume decreases, the gas supply volume of the gas will also decrease, resulting in a decrease in the output of the boiler. Background technique [0002] Boilers used for heating and providing hot water to general households are divided into oil-fired boilers and gas-fired boilers according...
