  • Analysis and comparison of four boilers
    1. The first advantage of oil-fired boilers is less equipment investment. Fuel oil burns quickly, and there is no coking problem in the furnace. The furnace volume heat load is relatively high, which can be nearly double that of coal-fired boilers. In this way, the volume of the furnace is significantly reduced, and the boiler steel frame is also ...

  • What are the precautions for thermal oil furnace?
    1. After the cold furnace is ignited, control the heating rate to 10 ° C / hour until 90-95 ° C. Because the viscosity of the oil in the cold furnace is large, the flow velocity in the tube on the heating surface is low, the oil film on the tube wall is thick, and the heat transfer conditions are poor.
