Water heating boiler has body arranged as water surrounding jacket that surrounds furnace chamber and gas-duct space that with cavity of water jacket forms closed surface of heat exchanger with gas channels, furnace chamber is separated from ash chamber with water-cooled fire grate that is connected to water jacket. It is equipped with additional water jacket as vessel connected to main water jacket and installed directly over heat exchanger, inside which with gap reservoir is provided, as tank equipped with branch pipe for supply of cold water. Besides that gas channels of heat exchanger are arranged as horizontal placed coaxially pipes each of which has square cross section that connects furnace chamber to smoke tube. At that heat exchanger is equipped with poking hatch installed in front of the body of boiler, and ash chamber–with ventilation branch pipe as flange installed on one of side surfaces of the body of boiler, besides that ash chamber is equipped with mechanism for fuel detachment arranged just under fire grate with possibility of vertical displacement between cuts of the grate by means of rod. |
