Boiler and the Method for Controlling Combustion of the Boiler

Abstract

The invention relates to a boiler and a method for controlling the combustion of the boiler, and particularly relates to the boiler and the method for controlling the combustion of the boiler which determines degree of contamination of exhaust chimney, through which exhaust gases are removed, regulates amount of supplied gas to maintain its combustion. Combustion in boiler control method includesthe following: a) setting target heat value to achieve target temperature, b) use of first database based on target heat value, c) measurement of speed of rotation of pressure ventilator and pressureof air created during rotation of air impact, d) using the second database based on the difference in rotation speed, air pressure difference and the target heat value to calculate the estimated fouling contamination value in accordance with the target heat value, e) using the third database in accordance with the estimation value of the chimney contamination for calculating the gas valve openingvalue and controlling the amount of the supplied gas.

Description

technical field [0001] The present invention relates to a boiler and a combustion control method of the boiler, in particular to a boiler and a combustion control method of the boiler capable of judging the clogging degree of an exhaust flue for discharging combustion gas and adjusting the gas supply to maintain the combustibility of the boiler. Background technique [0002] A gas boiler that utilizes heat generated by burning gas as a structure for heating or receiving hot water is usually equipped with an exhaust flue in which the burned combustion gas moves and is discharged to the outside access. [0003] At this time, carbon or nitrogen contained in the combustion gas may cause internal corrosion of the exhaust flue, mixture deposition may cause the inner diameter of the exhaust flue to decrease, and deformation or damage due to external force or headwind may flow in through the exhaust port Environmental factors such as environmental factors may also cause frequent ex...

AI Technical Summary

Problems solved by technology

[0003] At this time, carbon or nitrogen contained in the combustion gas may cause internal corrosion of the exhaust flue, mixture deposition may cause the inner diameter of the exhaust flue to decrease, and deformation or damage due to external force or headwind may flow in through the exhaust port Environmental factors such as environmental factors may also lead to frequent exhaust flue blockages

[0004] If the exhaust flue is clogged, the combustion gas cannot be discharged smoothly, so the pressure inside the combustion chamber increases, and the supply of gas decreases, resulting in a decrease in boiler efficiency and the occurrence of fire. ) drop problem
