The Y5-47 high-efficiency low-noise induced draft fan is designed for industrial boilers with capacities ranging from 0.2 to 20 t/h, which burn various types of coal and are equipped with smoke elimination and dust removal devices. It is available in both C-type and D-type transmissions. The dust content in the conveyed gas is greater than or equal to 150 mg/m3, and the inlet flue gas temperature is above 160°C but below 250°C. For temperatures exceeding 250°C, a stainless steel high-temperature boiler induced draft fan can be selected.
