The invention discloses a boiler combustion monitoring method and device. The method comprises the steps that smoke is injected into a monitoring unit; detecting the carbon dioxide concentration at the gas inlet end and recording data; oxygen is injected into the reaction furnace, so that carbon particles in the flue gas can be fully combusted in the furnace; detecting the concentration of carbon dioxide at the gas outlet end and recording data; and the amount of residual carbon carried in the flue gas is determined according to the concentration difference of carbon dioxide at different ports. The method has the beneficial effects that by detecting the carbon content of the fly ash in real time, a worker can conveniently and quickly record data and feed back maintenance, guiding operation is facilitated, the air-coal ratio is correctly adjusted, and the boiler combustion control level is improved; the index of the carbon content of the fly ash is reasonably controlled, the power generation cost is reduced, a
