Description

Technical Field

[0001] This utility model relates to the field of heating furnace manufacturing technology, and in particular to a heating furnace gas supply regulation system with an air intake temperature detection device. Background Technology

[0002] In existing heating boilers, the adequacy of air supply is generally determined by detecting the current of the fan, or by measuring air flow and pressure.

[0003] Because existing heating boilers lack an inlet air temperature detection device, they cannot adjust the air supply based on changes in inlet air temperature. This results in inaccurate judgment of air supply volume. Therefore, the structure needs to minimize the increase in inlet air temperature, as exemplified by the independent gas supply structure for gas-fired heating boilers disclosed in utility model patent CN208595691U. The specific defects of existing technologies in practical applications are as follows:

[0004] 1. The heat from the surface of the combustion chamber is directly radiated to the outside of the product, and cannot be fully utilized;

[0005] 2. Furthermore, the noise from the combustion chamber is directly transmitted to the outside of the product, increasing the overall product noise level;

[0006] 3. When installing a long coaxial flue pipe, the air density decreases after being heated by high-temperature flue gas, which can easily lead to insufficient air for combustion and incomplete combustion.

[0007] Therefore, how to make full use of intake air heat exchange, increase intake air temperature, improve the thermal efficiency of the heating boiler, and at the same time avoid incomplete combustion that may be caused by increased intake air temperature has become a technical problem that urgently needs to be solved by those skilled in the art.
