Abstract

The invention discloses a gas boiler constant-temperature operation method. The gas boiler constant-temperature operation method comprises the following steps that firstly, the normal operation process comprises the steps that water shunting valves, a backwater valve and a first gas valve are opened, a second gas valve and an adjusting valve are closed, and gas passes through the first gas valve,a first gas branch pipe and a gas inlet pipe and then is supplied to a gas boiler; the gas boiler and a circulating pump are started, hot water formed after heating enters a water supply main to be supplied to all heating units; backwater passes through the circulating pump and a backwater main to enter the gas boiler, and complete waterway circulation is formed; when a temperature monitoring andcontrolling mechanism of the gas boiler breaks down, the second gas valve is opened immediately, the first gas valve is closed, and the gas is supplied to the gas boiler through a gas boiler hot waterthermostatic valve; and the opening degree of the adjusting valve is controlled to control the water outlet temperature of the gas boiler. Operators do not need specialized training, and constant-temperature control can be achieved through operation of valve opening and closing. By controlling the opening degree of the adjusting valve, the set water outlet temperature of the gas boiler can be controlled.

Description

technical field [0001] The invention relates to the technical field of gas boiler heating, in particular to a constant temperature operation method of a gas boiler. Background technique [0002] With the development of economy and society, people's living standards are improving day by day, and the northeastern region has basically achieved full coverage of central heating. However, in the central region of my country, the winter temperature is low, and the coverage of central heating is still small, and many communities have not connected to heat. company. Therefore, in the central region of our country, many communities have their own heating systems. Coal-fired boilers are highly polluting and have been phased out; gas-fired boilers use gas (such as natural gas, liquefied petroleum gas, etc.) as fuel, and heat water through burners to achieve heating and provide hot water for living and bathing, with fast heating and low noise , no dust, it is an economical boiler variet...
