ThermalNet: A deep reinforcement learning-based combustion …

Conventional PF coal-fired boilers, currently being used in the power industry, use air for combustion in which the nitrogen from the air (approximately 79% vol) dilutes combustion products such as CO 2 and water vapor in the flue gas. During oxyfuel combustion, a combination of oxygen (typically of greater than 95% purity) and recycled flue gas is used for combustion of the fuel. A gas consisting mainly of CO 2 and water vapour is generated, with a concentration of CO 2 …

Pulverized coal-fired boiler - Wikipedia

Pulverized coal-fired boiler. A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox. The basic idea of a firing system using pulverised fuel is to
