PURPOSE:To continuously feed the heat quantity required for heating only rooms requiring to be heated by connecting a plurality of direct fired furnaces to a plurality of rooms to be heated by any of reciprocating branched ducts exclusively used for the direct fired furnaces and controlling the furnaces at the heating load of the room. CONSTITUTION:Heat feeding passages 2 from a plurality of direct fired furnaces 1 are connected to a plurality of outgoing branch pipes 4 through a distributing pipe 3, and terminal end heat radiating parts 4A of the branch pipes 4 are opened in a plurality of rooms 5 requiring to be heated. A plurality of return branch pipes 6 opened in respective rooms 5 are connected to return air feed pipes 8 through a concentration pipe 7, and the return air feed pipes 8 are connected to the furnaces 1. During this time, heat feed fans 9 and opening and closing dampers 10 are installed at arbitrary positions and operated. That is, the necessary heat quantity is fed to only rooms to be heated, and hence there is no wasteful consumption of fuel. Duct diameter saving is realized due to the high temperature heat feed, and rubishes, sounds and odor are removed. |
