Problems solved by technology

[0022] However, in the case of using the aforementioned DC blower 10 and the air proportional control valve 47, there is a problem that the price of the product is expensive, and the amount of gas set by the air proportional control valve 47 does not coincide with the entire air volume, resulting in Error, compare the price of components, not practical, low efficiency
[0023] In addition, there is a problem of increasing the price of the boiler due to the use of the expensive DC blower 10

Abstract

The present invention is one boiler with controlled air proportion. Cheap AC blower, current proportion gas valve and air amount sensor are used, and the current proportion gas valve is controlled directly by the air amount to produce proper gas amount in whole air amount range. Optimal heat amount may be supplied to produce hot water in the set temperature. Even if in abnormal weather condition, the boiler may be ignited in optimal condition to reach optimal burning performance. The present invention has the advantages of high efficiency and saving in fuel.

Description

technical field [0001] The present invention relates to an air proportional control boiler. More specifically, the present invention relates to a low-cost AC blower (i.e., an AC blower), a current proportional air valve and an air volume sensor. The gas volume can be adjusted within the entire range of the air volume, and an air proportional control boiler can be efficiently controlled over the entire range of the air volume using inexpensive equipment. Background technique [0002] Heating equipment and hot water boilers used in general households are roughly divided into oil-fired boilers and gas-fired boilers according to the fuel used. Among them, recently, for the sake of reducing air pollution and ease of use, gas-fired boilers are mainly used, and as their fuel, liquefied natural gas (LNG) is used. [0003] Gas boilers are divided into condensing and non-condensing according to the heat exchanger used to heat the heating water. Among them, the condensing gas boiler ...
