<p>PURPOSE:To remove the NO and NO2 exhausted into room and permit comfortable heating by mounting a filter which removes harmful gases such as NO and NOx at ordinary temp. to a heater with a fan. CONSTITUTION:The hot wind by the exhaust gas burned in a burner 3 is blown out into a room through a blow-out port 4 and warms the room inside, after which it is passed through the NOx removing filter 1 installed in the air suction port by a fan 2 and is gain blown out into the room. This NOx removing filter 1 consists of an NO removing filter prepared by kneading and molding NaClO2 or KMnO4 which is an oxidation absorbent for NO with an alkali and cement material, and an NO2 removing filter prepared by kneading and molding an alkali and powder carbon with a cement material. As a result, the NO and NO2 exhaust into the room by the heater with fan are removed nearly perfectly.</p> |
