Different degrees of heat loss often occur in the process of practical application of electric furnace for trolley, which mainly manifests in the following aspects.
Exhaust heat loss: The heat taken away by the discharge of flue gas is called exhaust heat loss. This kind of heat loss can reach about 4%-8%, which is recognized as the biggest one in the heat loss of electric car furnace. The larger the volume of general smoke, the higher the exhaust temperature, the more heat loss.
Incomplete fuel combustion loss: The heat loss caused when fuel is burned in the furnace, usually some solid combustibles are excluded from the furnace without participating in combustion or without burning out. It includes the loss of coal leakage that part of the fuel is discharged into the ash bucket through the grate; The ash loss caused by the unburned combustibles wrapped in ash and discharged into ash bucket; Loss of fly ash from unburned carbon particles carried away by smoke. Among them, the heat lost by fly ash is the largest.
Heat loss: due to the metal structure of boiler unit, furnace wall flue are exposed to the atmosphere, they will be to the outside air to lose a certain amount of heat, this is the heat loss. Heat dissipation loss is usually directly related to the external area, heat preservation and thermal insulation of electric furnace unit.
