Problems solved by technology

[0002] At present, coal-fired boilers and biomass boilers are still very common and widely used thermal equipment. The existing coal-fired and biomass boilers are basically direct-fired boilers, that is, after coal-fired and biomass Direct combustion produces heat. This kind of direct-fired boiler has a low fuel heat utilization rate. The heat utilization rate of most direct-fired coal-fired boilers is not more than 60%, which wastes energy, and the combustion is not complete. The pollution is serious, and it has long been a restricted equipment.
[0003] At the same time, the safety performance of existing boilers is poor, and it is easy to cause the flame in the combustion chamber of the boiler to return to the fuel bunker, which may easily lead to problems such as explosion and accidental fire.

Embodiment 1

[0121] The present invention drives the inner casing 5 to rotate in the outer casing 4 through the feeding motor 7, and in the process of rotation, the fuel switching port 501 is switched correspondingly to the feed port and the discharge port 43 respectively, that is, when the fuel switching port 501 is connected to the When the feed port corresponds to receive the fuel in the fuel tank, and as the inner sleeve 5 rotates in the outer sleeve 4, when the fuel conversion port 501 corresponds to the discharge port 43, the fuel entering the inner sleeve 5 passes through the outlet The port 43 enters the feed pipe 102, the feed pipe 102 delivers the fuel to the grate assembly 211 in the combustion chamber 2, and ignites the fuel through the igniter 200;

[0122] During the combustion process of the fuel on the grate assembly 211, the air chamber 216 stores wind through the vent and then introduces the wind to the grate assembly 211 through the air guide hole 201, thereby acceleratin...

Embodiment 2

[0129] On the basis of Embodiment 1, a water outlet temperature sensor is provided on the outlet 101, a flue gas temperature sensor is provided on the connecting flange 20 of the smoke exhaust machine, a water inlet temperature sensor is provided on the water inlet 103, and the water temperature sensor, smoke The gas temperature sensor, the water inlet temperature sensor, the igniter 200 and the grate drive reduction motor 212 are all connected to PLC, so that the PLC controls the speed of the fire grate drive reduction motor 212 and the speed of the feed motor 7 according to various temperature information received. The rotation speed and the working state of the igniter 200 are controlled, so as to control the wind speed and air volume in the air chamber 216 and to control the feeding amount of the fuel, thereby controlling the combustion of the fuel.

[0130] Each embodiment in this specification is described in a progressive manner, each embodiment focuses on the difference...

Embodiment 3

[0132] On the basis of Embodiment 1 and Embodiment 2, the two ends of the fire grate air pipe 204 are closed, and the two ends of the pipe wall of the fire grate air pipe 204 are respectively connected with a cold water inlet pipe 294 and a hot water outlet pipe 284. Import cold water into the grate air duct 204 through the cold water introduction pipe 294 to realize the cooling effect on the fire grate air duct 204, avoid the problem that the fire grate air duct 204 is easily damaged under long-term high temperature conditions, and pass the hot water outlet pipe 284 to The hot water formed after the heat exchange between the cold water and the grate air duct 204 is exported through the hot water outlet pipe 284 to realize the circulation of the cold water in the fire grate air duct 204 and realize the continuous cooling effect on the fire grate air duct 204 .

Abstract

The invention discloses a backfire-proof automatic slagging boiler. The combustion chamber is arranged at the bottom of the main body of the water tank and is located in the middle of the legs of the two water tanks; a grate driving deceleration motor, a motor output turntable, an eccentric shaft and a transmission connecting rod are all arranged. In the air chamber, and located at the second side of the air chamber, and the motor output turntable is fixed on the output shaft of the grate drive geared motor, eccentrically fixed on the disk surface of the motor output turntable, and the first end of the transmission link is connected to the eccentric The shaft is hinged, and the second end is hinged with the grate assembly; the rotary fuel feeder is fixed on the nozzle of the first end of the feeding pipe, and communicates with the nozzle at one end of the feeding pipe, and the rotary fuel feeder is set on the The bottom of the fuel outlet of the fuel bunker communicates with the fuel outlet; the feed pipe passes through the side wall of the combustion chamber, and the second end nozzle of the feed pipe communicates with the grate assembly. The invention provides an automatic slag-discharging boiler for anti-tempering, which improves combustion efficiency and safety performance at the same time.
