Problems solved by technology

[0003] Current steam boilers usually use a pressure sensor to detect the air pressure to control the output air pressure of the steam boiler, but because the high-temperature steam output by the steam boiler has a great influence on the accuracy of the pressure sensor, and the high-temperature-resistant pressure sensor has high purchase costs and economic benefits. Low; and the method of using the pressure sensor cannot realize the monitoring of the output steam temperature, and cannot realize the synchronous control of temperature and pressure

Abstract

The invention discloses a method for adjusting the pressure of a steam boiler based on the temperature. The method includes the following steps that firstly, a saturated steam temperature-air pressurechange test is conducted, and a temperature-air pressure comparison table is drawn, wherein the designated air pressure P0, meeting the pressure requirement, in the boiler is set; secondly, the temperature-air pressure comparison table is looked up according to the designated air pressure P0 in the first step, and the designated steam temperature T0 meeting the pressure need is obtained; thirdly,the steam temperature T in the steam boiler is detected; and fourthly, the steam boiler is controlled to be heated till the steam temperature T in the steam boiler reaches the designated steam temperature T0, and the air pressure P in the steam boiler reaches the designated air pressure P0. By means of the method, the idea is innovative, the method for adjusting the pressure of the steam boiler based on the temperature is adopted, the cost of a pressure sensor is saved, the economic benefits are improved, the temperature of output steam is better controlled, and temperature and pressure synchronous control is achieved.

Description

technical field [0001] The invention relates to the technical field of steam boilers, in particular to a method for adjusting the pressure of steam boilers based on temperature. Background technique [0002] Boiler is a kind of energy conversion equipment. The energy input to the boiler is in the form of chemical energy in fuel, electric energy, heat energy of high-temperature flue gas, etc. After conversion by the boiler, it outputs steam, high-temperature water or organic heat carrier with certain heat energy. . A steam boiler refers to an industrial boiler that heats water to a certain temperature and produces high-temperature steam. Its working principle is that the heat released by heating equipment (burners, electric heating tubes, etc.) is absorbed by water and boiled to vaporize, and a large amount of steam is generated and enters the steam drum for steam-water separation (except DC furnace), and the separated saturated steam enters the delivery pipeline.
