Embodiment 1

[0023] A gas-fired boiler air intake device, such as figure 1 As shown, it is used for a gas boiler 1, including a controller 4, a temperature sensor connected to the controller 4 and two frequency conversion fans 2 of the same type, and the two frequency conversion fans 2 are symmetrically arranged on the ground on both sides of the gas boiler 1 , are respectively connected to the combustion chamber of the gas boiler 1 through the air supply pipe 3. In this embodiment, the frequency conversion fan 2 is a three-phase AC frequency conversion fan, and the air supply pipe 3 is L-shaped, with an elbow at the bend. The temperature sensor is set in the combustion chamber of the gas boiler 1 , and the controller 4 receives the signal from the temperature sensor and synchronously adjusts the air volume of the two frequency conversion fans 2 to blow air for the gas boiler 1 together.

[0024] In this embodiment, a magneto-rheological shock absorber 5 is provided between the variable fr...

Abstract

The invention relates to air intake equipment of a gas-fired boiler. The air intake equipment is used for the gas-fired boiler (1) and comprises a controller (4) and a temperature sensor and two variable frequency draught fans (2) of the same type connected to the controller (4) separately, the variable frequency draught fans are symmetrically arranged on the ground of the two sides of the gas-fired boiler (1) and connected to a combustion chamber of the gas-fired boiler (1) through a blast pipe (3) separately, the temperature sensor is arranged in the combustion chamber of the gas-fired boiler (1), and the controller (4) receives signals of the temperature sensor to synchronously adjust the blast capacity of the variable frequency draught fans (2). Compared with the prior art, the air intake equipment of the gas-fired boiler has the advantages of being little in vibration and noise pollution, convenient to operate and maintain and the like.

Description

technical field [0001] The invention belongs to the technical field of gas boilers, and in particular relates to an air inlet device of a gas boiler. Background technique [0002] At present, general gas-fired boilers are equipped with a blower due to the working characteristics. When the boiler is burning, a large amount of air is sent into the furnace by the blower. The existing gas-fired boiler installs the blower on the top of the boiler body. When the boiler is operating under heavy load, the blower rotates at full speed. Generates a lot of vibration. It resonates with the vibration generated by the combustion of the boiler body, resulting in unstable signals of electrical equipment, frequent failures, reduced equipment efficiency, and increased maintenance costs. Contents of the invention [0003] The object of the present invention is to provide a gas-fired boiler air intake device in order to overcome the above-mentioned defects in the prior art. [0004] The pur...
