JPH01184006A - Device for preventing contamination in heat exchanger of circulation type bath furnace - Google Patents

Abstract

PURPOSE:To remove dirty things suspended in the water of a bath tub to prevent the interior of a heat exchanger from being fouled, avoiding thereby a lowering of thermal efficiency, by inserting a bag having an elastic frame on its opening into a bath-tub-connection metallic member located on the lower side of a circulation type bath furnace of a bath tub. CONSTITUTION:A bag 1 of fine mesh provided with an elastic frame having a taper thereon is disposed in a bath-tub-connection metallic member of a bath tub in such a manner that no gap is left between the frame and the metallic member. The opposite end of the metallic member is connected with a heat exchanger which is heated by a burner. The water in the bath tub is led to the heat exchanger through the metallic member on the lower side of the bath tub by convection and then returned into the bath tub from an upper bath-tub- connection metallic member, whereby dirty things suspended in the water of the bath tub are removed by the bag.

When taking a bath in a circulating air kettle that utilizes the principle of heat convection, the water in the bathtub flows through the lower bathtub due to heat convection. It enters the heat exchanger through the connecting fitting and comes out through the upper tub fitting.
