Energy-saving and environment-friendly closed-loop control methanol heating stove

Abstract

The invention provides an energy-saving and environment-friendly closed-loop control methanol heating stove. In the working process, a controller regulates and controls a frequency conversion fan and a throttle valve to work in a coordinated mode according to the external air pressure value detected by an atmospheric pressure sensor, and the air pressure and the air volume matched with the external air pressure value are output. The controller controls a combustor to do ignition work, the controller controls a variable-frequency electromagnetic pump to eject methyl alcohol to an igniter of the combustor, the methyl alcohol is ignited after passing through the igniter of the combustor and generates flames, and the flames enter a combustion chamber under the action of wind power. And when a flame detection sensor detects that after the methyl alcohol is ignited, the controller controls the igniter of the combustor to stop working. And the temperature of the combustion chamber and the temperature of a smoke exhaust pipe rise, and refrigerant water in a heat exchange water tank is heated. The controller regulates and controls the ignition mechanism and the oil injection mechanism to work coordinately according to the oxygen concentration, detected by a wide-range oxygen sensor, in tail smoke exhausted by the smoke exhaust pipe, and therefore it is guaranteed that high combustion efficiency of the methyl alcohol can be maintained.

Description

technical field [0001] The invention relates to the field of heating furnaces, in particular to an energy-saving and environment-friendly closed-loop control methanol heating furnace. Background technique [0002] Heating boilers can be divided into electric heating boilers, oil heating boilers, gas heating boilers, coal-fired heating boilers, etc. according to different fuels. According to whether the boiler is under pressure, it can be divided into normal pressure heating boiler and pressure heating boiler. In the past, pressurized hot water heating boilers were mainly used for heating high-rise buildings. Due to the increase in water heating accessories and the improvement of installation technology, atmospheric pressure hot water boilers are mostly used for heating in both high-rise buildings and low-rise buildings. Fuel-fired heating boilers are equipment that use natural gas and liquefied petroleum gas as fuel for heating. Among the fuel-fired heating boilers, there...
