Problems solved by technology

At present, most of the existing boiler fuel addition and ventilation control are done manually based on experience. On the one hand, it is not only inefficient and wastes manpower, but on the other hand, the accuracy of the adjustment is still to be verified. It may not be able to achieve the best for improving the combustion efficiency of the boiler.
In addition, if it is done manually, it is also dangerous.

Abstract

The invention provides a full-automatic combustion control device for boilers. The full-automatic combustion control device comprises a CO / CO2 content detecting and setting device in a chimney, a computer control center, a mechanical ventilator, an adjusting control device of the mechanical ventilator and a combustion adding and controlling device; a CO / CO2 smoke content detector is a Testo 350Pro analyzer with the temperature tolerance limit reaching up to 500DEG C, so that requirements on high-temperature measurement can be met. Compared with the prior art, the full-automatic combustion control device has the advantages that feasibility of full-automatic fuel adding and ventilation regulating is ensured; generalization performance of the device is high, and the device can be used in newly-manufactured boilers and popularized to be used in existing boiler transformation; the full-automatic combustion control device is simple in structure, convenient to operate, low in running cost, good in safety and long in service life circle.

Description

technical field [0001] The patent of the present invention belongs to the technical field of fully automatic control of boiler combustion. Specifically, the present invention relates to a fully automatic combustion control device for boilers. 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. . Widely used in daily life of residents, power stations, ships, locomotives and industrial and mining industries. During the operation of the boiler, fuel and air must be continuously sent to the furnace, and the combustion products are discharged from the furnace and flue. Fuel is a necessary condition to ensure continuous combustion. Currently, there are artificial and mechanical additions. Ventil...
