Problems solved by technology

[0005] At present, the intelligence level of the boiler is not high, and it still stays at the original design around the 1980s. For example, the blast control of the boiler lacks effective reference data, and the combustion efficiency inside the boiler cannot be guaranteed.

Embodiment Construction

[0016] Embodiments of the automatic blast control type boiler of the present invention will be described in detail below.

[0017] The main working principle of the boiler is a thermal device that uses the heat energy released after fuel combustion or the waste heat in industrial production to transfer to the water in the container to make the water reach the required temperature or steam at a certain pressure. The boiler is operated in two parts of the "pot" and "furnace" at the same time. After the water enters the boiler, the heating surface of the boiler in the steam-water system transfers the absorbed heat to the water, so that the water is heated into hot water at a certain temperature and pressure or steam is drawn out. application. In the part of the combustion equipment, the combustion of the fuel continuously releases heat. The high-temperature flue gas generated by the combustion transfers the heat to the heating surface of the boiler through heat transmission, and ...

Abstract

The invention relates to an automatic air blowing control type boiler. The automatic air blowing control type boiler comprises multiple pieces of concentration measurement equipment and an analysis control switch. The concentration measurement equipment is arranged at different positions in the boiler correspondingly and used for measuring the carbon monoxide concentrations of the different positions in the boiler so as to acquire various carbon monoxide concentration values, and the carbon monoxide concentration values are output. The analysis control switch is connected with the multiple pieces of concentration measurement equipment and is used for receiving the carbon monoxide concentration values, calculating the average value of the carbon monoxide concentration values as the concentration average value and emitting an analysis start signal when the concentration average value is larger than a preset concentration threshold value, and the analysis control switch is further used for emitting an analysis shutoff signal when the concentration average value is smaller than or equal to the preset concentration threshold value. By means of the automatic air blowing control type boiler, the intelligent level of air blowing control in the boiler can be increased.

Description

technical field [0001] The invention relates to the field of boilers, in particular to an automatic blast control boiler. Background technique [0002] The flow circulation of the working medium in the water-cooled wall tube of the natural circulation boiler relies on the difference in specific gravity of the working medium between the ascending and descending tubes to establish a circulating pressure head to generate natural circulation. This type of boiler is only applicable to subcritical pressure. [0003] To control the auxiliary circulation boiler, a circulation pump is added between the water wall and the downcomer to overcome the flow resistance and ensure the safety and reliability of the water circulation. It is suitable for boilers with subcritical and near critical pressures. [0004] The once-through boiler is a boiler that passes through each heating surface once by relying on the pressure of the feed water pump from water to the outlet of superheated steam. It...
