Pressurized heating and bathing dual-purpose furnace

Abstract

A pressurized heating and bathing dual-purpose furnace, including a burner and a gas inlet pipe connected to the burner, characterized in that the gas inlet pipe is provided with a boosting ratio control device, and the boosting ratio control device includes a casing , impeller, rotating motor and pushing motor, the housing has a cone portion, and a gap is formed between the impeller and the aforementioned tapered portion; the rotating shaft of the rotating motor extends into the aforementioned housing and is connected with the impeller; the output shaft of the pushing motor is connected to the aforementioned The casing of the rotating motor is connected and can drive the rotating motor to move back and forth, so that the gap between the impeller and the cone can be adjusted. The gap between the impeller and the shell can be adjusted to realize the adjustment of the intake flow, and the rotation of the impeller can realize the function of gas boosting.

Description

technical field [0001] The invention relates to a dual-purpose stove for heating and bathing. Background technique [0002] The basic structure of the dual-purpose furnace includes gas inlet pipe, heating pipe, bathing pipe, plate heat exchanger, burner and expansion tank. The gas inlet pipe is equipped with a gas proportional valve, which controls the opening of the gas passage through an electromagnet. The size thus controls the gas flow. The gas flow rate is greatly affected by the gas supply pressure. When the gas supply pressure is insufficient in winter, the gas proportional valve cannot guarantee the gas flow even if it reaches the maximum opening, and the maximum gas flow can only be less than the gas supply pressure. The maximum and minimum loads of gas heating and hot water dual-purpose boilers shift downwards, resulting in failures such as insufficient maximum heat load, difficulty in ignition, and flameout at minimum load; Faults such as unstable gas output. ...

AI Technical Summary

Problems solved by technology

[0005] The burner is burned by mixing air and gas. There is a large amount of nitrogen in the air. After high-temperature combustion, a large amount of nitrogen oxides will be produced, and nitrogen oxides will cause air pollution. At the same time, part of the nitrogen will take away heat and reduce combustion efficiency.

In addition, as the core component of the expansion tank, after a long period of use, the lack of air pressure often occurs, which causes the internal pressure of the system to increase continuously during the operation of the dual-purpose furnace, and usually needs to be repaired and supplemented with nitrogen.
