Fuel gas heating energy-saving furnace

Abstract

The utility model discloses a fuel gas heating energy-saving furnace, which relates to the field of heating and drying of coating equipment, and comprises an oven body and a burner box body, the burner box body is arranged below the oven body, a gridiron is arranged in the oven body, a guide rail is arranged below the gridiron, guide wheels are arranged at four corners of the bottom of the gridiron, and the guide wheels are connected with the burner box body. The gridiron is arranged on the guide rail through four guide wheels at the bottom, a hanging rod is transversely arranged in the gridiron, and a first air return opening and a first hot air outlet are formed in the bottom of the oven body. The device is reasonable in structural design, easy to operate and convenient to use, hot air is collected through the heat energy recovery interlayer and conveyed to the combustor for combustion supporting through the variable-frequency combustion-supporting fan and the energy-saving hot air guide pipe, traditional cold air combustion supporting is replaced, energy consumption of the combustor is reduced, the gas utilization rate is increased, and the energy cost is effectively saved. The hot air circulation system enables heat in the furnace to be distributed more evenly, the product drying effect is consistent, the situation that the subsequent spraying procedure quality is affected due to uneven drying is avoided, and the product coating quality is guaranteed.
