Abstract
The invention discloses a smoke-free waste heat recovery boiler. According to the smoke-free waste heat recovery boiler, coal in a hearth is completely combusted through a rotational flow combustion device and a combustion supporting device. High-temperature gas generated in the combustion process flows through transverse water pipes and a waste heat dedusting device at the tail; meanwhile, natural air enters the waste heat dedusting device through an air inlet of an air blower, and the natural gas and the high-temperature flue gas generated in the combustion process conduct heat exchange, so that the temperature is raised; meanwhile, the temperature of the high-temperature gas generated in the combustion process is lowered, and then the temperature-lowered high-temperature gas enters the hearth of the boiler through an air outlet to support combustion of fuel, so that the temperature in the hearth is raised; when the high-temperature flue gas passes through the waste heat dedusting device, tap water enters the waste heat dedusting device through a water inlet and conducts heat exchange, so that the temperature of the tap water is raised; the generated hot water can be used as drinking water or bath water or used for heat supply and can also be added into a boiler body for raising the temperature of inflow water of the boiler; as a result, the efficiency of the boiler is improved, the fuel is saved, the environmental protection effect completely reaches the standards, the coal can be saved by more than 50%, the water boiling time is shortened by more than twice, and the exhaust gas temperature of the boiler maintains below 100 DEG C.
