After the temperature of the heat transfer medium rises, the end of the heat transfer tube located in the auxiliary furnace transfers heat to the cold water entering the auxiliary furnace. Heating it, the temperature of the cold water rises and turns into hot water, and then flows out from the water outlet on the upper surface of the sealed furnace body, the cylinder starts, the output shaft of the cylinder drives the connecting rod, the connecting rod drives the push plate to move, and the push plate moves along the inclination of the supporting plate The face moves downward, and the fuel feeding device feeds new fuel at the same time. After the new fuel falls on the supporting plate, the connecting rod is pushed back, and the pushed back connecting rod pushes back the push plate, and the pushed back push plate can push back The new fuel on the supporting plate is pushed along the inclined surface of the supporting plate. During the upward movement, the new fuel pushes the ashes produced by the previous combustion towards the direction of the ash discharge box, and the ashes are gradually pushed into the ash discharge box during the reciprocating pushing process. At the same time, during the reciprocating push process, the push plate can push away the agglomerated fuel on the support plate, so that the fuel can be burned more fully. At the same time, the blower sends the wind into the combustion chamber from the outside, and the wind can enter the ash discharge box through the combustion chamber And the combustion chamber can flow through the furnace, the stove and the heat utilization room in turn, and finally flow out from the exhaust pipe. The blower can prevent the ashes on the support plate from accumulating in the combustion chamber, and the ashes will move to the ash discharge box and fall into the discharge chamber. The ash sieving device is placed on the vibrating sieve belt, and the vibrating machine drives the vibrating sieve belt to vibrate. The ashes gradually move out of the ash discharge box on the vibrating vibrating sieve belt. During the movement, the ashes gradually fall out of the vibrating sieve from the mesh. The unburned fuel in the ashes will eventually fall out of the ash discharge box through the vibrating screen material belt and be recycled. At the same time, the protective plate can prevent the unburned fuel from falling out of the vibrating screen material belt during vibration. When placed on the cooktop, the cooktop cover can be covered on the cooktop, so that the high-temperature hot gas generated by the combustion of fuel in the combustion chamber and the furnace will not flow out of the cooktop and be wasted, further improving the utilization rate of heat energy and reducing In order to avoid the waste of energy, the invention provides an energy-saving and environment-friendly boiler capable of making full use of heat energy, less environmental pollution and high working efficiency and its operating method.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of the present invention. within the scope of protection.
