A gas combustion intelligent control device

Abstract

The invention relates to the technical field of gas boilers of main cooking equipment in kitchen matching, in particular to an intelligent control device for gas combustion. The intelligent control device for gas combustion comprises a control system, a flue methane sensor, a second time relay, a flue temperature sensor, a first time relay, a second acousto-optic alarm device, an igniter, an electromagnetic valve, a first acousto-optic alarm device, a flow regulating valve, a variable frequency blower, an air flow meter, an air guide pipe, a gas flow meter, a stove main gas pipe, a second infrared temperature sensor, a first tempering prevention valve, a second tempering prevention valve, a long open fire gas pipe and a first infrared temperature sensor. According to the intelligent control device for gas combustion, automatic and intelligent regulation of long open fire, gas and air required by gas combustion is achieved, potential safety hazards during gas combustion are eliminated,and the safety of the gas combustion device is improved.

Description

technical field [0001] The invention relates to a gas boiler, which is the main cooking equipment used in kitchen matching, and in particular to an intelligent control device for gas combustion. Background technique [0002] At present, the cooking gas cooker has become the main tool for cooking various dishes in the kitchen. Traditional cooking gas boilers consume a lot of energy and have low energy efficiency. They can’t even reach the basic 45% thermal efficiency index. Especially the blast stoves can meet the combustion firepower required for cooking and increase the heat load, but the energy efficiency is very low. If the thermal efficiency is only between 35% and 38%, more than 60% of the combustion heat energy will be wasted in vain through the flue. [0003] In the process of gas combustion, it is necessary to continuously supplement sufficient oxygen to make the gas fully combustible. However, the existing gas combustion adjustment method is generally to manually a...

Traditional cooking gas boilers consume a lot of energy and have low energy efficiency. They can’t even reach the basic 45% thermal efficiency index. Especially the blast stoves can meet the combustion firepower required for cooking and increase the heat load, but the energy efficiency is very low. The thermal efficiency is only between 35% and 38%, and more than 60% of the combustion heat energy is wasted in vain through the flue.

[0003] In the process of gas combustion, it is necessary to continuously supplement sufficient oxygen to make the gas fully combustible. However, the existing gas combustion adjustment method is generally to manually adjust the gas flow and air flow. Complete combustion, increase the air flow too much, so that the heat of combustion will be taken away by too much air, and if the air flow is not increased, people often worry about whether the gas can be fully burned, and the methane concentration is 5%- Under 15% of the conditions, it will explode when encountering an open flame, and there are potential safety hazards
