Environmentally-friendly boiler for power plant

The invention discloses an environmentally-friendly boiler for a power plant. The environmentally-friendly boiler comprises a boiler body, a fixed hood, a fixed plate and an induced air hood. A synchronous motor arranged in the fixed hood drives a roller and drives a tank chain to directionally rotate in the boiler body, so that when a coal feeder on one side of the boiler body supplies coal in the boiler body, the transported coal is effectively flattened and transported; and meanwhile, a dredging frame is arranged on one side of the inner wall of the boiler body through the fixed plate, a mounting hood is arranged at the periphery of the boiler body, a low-speed motor arranged in the mounting hood drives a third gear, and the third gear drives a second gear and a first gear in the boiler, so that the dredging frame directionally deviates on the fixed plate through a supporting shaft effectively, and when coal flattened by the tank chain is flattened, effective dredging and uniformlydistribution can achieve
