Control method of steam system

Abstract

The invention relates to a control method of a steam system, which comprises the following steps: controlling rotating speed change of a fan to form a plurality of wind speed gears, wherein the gears comprise a high-speed gear and a low-speed gear, and the valve opening degree of a proportional valve is changed along with the wind speed; detecting the state of a steam valve to determine the number of unit cabinets in work, and enabling the high-speed gear and the low-speed gear to be matched according to the number of the unit cabinets in work; enabling temperature sensors in the unit cabinet bodies in work to sense the temperature in the unit cabinet bodies to obtain the measured temperature, and switching the gear of the fan to the high-speed gear if any obtained measured temperature is smaller than or equal to the set lower limit temperature; and if all the obtained measured temperatures are larger than or equal to the set upper limit temperature, switching the gear of the fan to the low-speed gear. According to the control method of the steam system provided in the invention, the energy consumption of the steam system is reduced through the control mode, and the effects of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to the field of steam heating cooking, in particular to a method for controlling a steam system. Background technique [0002] The steam system generally includes steam generators, steam cabinets and other equipment. The steam generator is equipped with a water tank and a combustion heat exchange chamber, so that the water in the water tank is heated to generate steam, and the steam is transported to the steam cabinet for heating; the existing steam system generally The amount of steam generated in the steam generator cannot be controlled. When too much steam is generated and transported to the steam cabinet, because the pressure in the steam cabinet is too high, the steam will be discharged through the pressure relief valve on the steam cabinet to avoid accidents and be discharged directly. Steam leads to energy loss, which is not conducive to the energy saving and emission reduction of the entire steam system. Contents of the ...
