fossil fuel gas control system for firing coal-fired boiler

摘要

The present invention is a boiler combustion chamber for burning fossil fuel; An air generator for generating air for burning fossil fuels; A heat exchanger configured to receive air generated from an air generator through a press-in ventilator and heat the air to provide combustion air, or to heat a fossil fuel gas combusted through a boiler combustion chamber to provide a manned ventilator; An electric dust collector configured to collect foreign substances when the fossil fuel is burned through the boiler combustion chamber; A stack of fossil fuel gas heated through a heat exchanger and filtered through an electrostatic precipitator to be supplied from a manned ventilator and discharged to the outside; An air opening and closing portion provided between the heat exchanger and the pressurized ventilator to open and close the air introduced through the pressurized ventilator; A fossil fuel gas opening / closing unit provided between the electrostatic precipitator and the manned ventilator to open and close the fossil fuel gas to be discharged through the manned ventilator; And fossil fuel gas discharged from the boiler combustion chamber when the fossil fuel is discharged from the boiler combustion chamber, when the fossil fuel gas discharge time is out of the fossil fuel gas discharge time range. Comprising a combustion situation analysis device for calculating the discharge time of the fossil fuel gas to be corrected to fit the range, and opening the air opening and closing unit to supply air generated from the air generator to the heat exchanger in accordance with the discharge time of the fossil fuel gas to be corrected do.
