Description

Technical Field

[0001] This patent relates to the field of condensate heating, specifically a condensate heating device for a gas boiler. Background Technology

[0002] Currently, in power plants or energy and chemical enterprises, condensate heaters are installed at the tail end of waste heat boilers to improve energy efficiency. After steam completes its work in the turbine, it is cooled into condensate by the condenser. The condensate pump pressurizes the condensate and sends it to the condensate heater. The exhaust gas temperature at the tail end of existing waste heat boilers is generally around 150℃ to 180℃, which is high, resulting in heat waste and low combined cycle efficiency. To reduce the exhaust gas temperature, condensate heaters can be installed at the tail end of the preheating boiler. Currently, many condensate heaters are installed in the upward direction of the flue gas flow, using eight rows of finned tube panels. These eight rows are divided into two sections: four rows and four rows of panels, which can significantly reduce the exhaust gas temperature.

[0003] However, dust easily accumulates on the outer wall of existing heaters, affecting their heating performance. Therefore, improvements to the existing technology are necessary. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this patent is to provide a condensate heating device for a gas boiler.

[0005] The technical solution adopted by this patent to solve its technical problem is: a condensate heating device for a gas boiler, including a gas boiler body, a heating element is installed at the top of the gas boiler body, and a discharge cylinder is installed at the top of the heating element.

[0006] The heating element is internally fitted with a fixing body, and the outer wall of the fixing body is fitted to the inner wall of the discharge cylinder.

[0007] The fixed body has a heating cavity inside, and a heater is installed inside the heating cavity;

[0008] Vibration grooves are provided on both inner walls of the heating element, and vibration components are assembled inside the vibration grooves.

[0009] The two outer walls of the fixed body are provided with ear plates, and the ear plates are connected to the vibration assembly.

[0010] The vibration assembly includes a piston cylinder, a piston rod inserted inside the piston cylinder, a screw rod installed at the top of the piston cylinder, and a screw hole opened on the side wall of the ear plate, through which the ear plate is installed on the outside of the screw rod.

[0011] Furthermore, a vibration spring is fitted around the piston cylinder, piston rod, and screw, and a fixing plate is installed at the bottom end of the piston rod, with the fixing plate installed at the bottom of the vibration groove.

[0012] Furthermore, an adjusting nut is screwed onto the outside of the screw, and the vibration spring is disposed between the vibration plate and the adjusting nut.

[0013] Furthermore, the heater includes an upper header, a lower header, and finned tubes.

[0014] Furthermore, a fixing base is installed at the bottom of the main body of the gas boiler.

[0015] Furthermore, a controller is provided on the outer wall of the heating element, and the heater is electrically connected to the controller.

[0016] The beneficial effects of this patent are:

[0017] A condensate heating device for a gas boiler has a simple structure and is easy to operate. By setting a heating element inside the heating body and installing a nine-row tube screen, the heat exchange area of ​​the condensate heating device is increased, the exhaust gas temperature at the tail of the waste heat boiler is reduced, the exhaust gas heat at the tail of the waste heat boiler is recovered, and the thermal efficiency of the combined cycle unit is improved. Furthermore, a vibration component is installed between the heating element and the stationary body, so that the vibration generated during discharge vibrates the dust hanging on the stationary body, thereby improving the overall working efficiency.

There is a threaded fit between the screw 8 at the top of the piston cylinder 16 and the screw hole 12 on the ear plate 13, thereby installing the ear plate 13 on the screw 8.

[0030] Vibration springs 17 are fitted around the piston cylinder 16, piston rod 15 and screw 8. A fixing plate 14 is installed at the bottom of the piston rod 15.
