PROBLEM TO BE SOLVED: To provide a boiler for supplying heat source not kept in high pressure but kept at high temperature, capable of reducing running cost including fuel fee and controlling temperature of the heat source.SOLUTION: This invention relates to a boiler in which wood chips becoming waste are used for fuel, the wood chips are fed into "combustion part", smoke of high temperature generated by burning the wood chips is passed through a pipe passing in a tank filled with oil acting as thermal medium that does not work as one showing a high pressure at "the heat exchanging part" but enables high temperature to be generated, thereby the wood chips may supply a heat source for drying wood and further a shutter at the heat exchanging part is opened or closed and the high temperature smoke is passed or is not passed through the tank filled with oil acting as thermal medium also to enable the heat source temperature control to be carried out.SELECTED DRAWING: Figure 1 |
