Water-tube type central-reverse-flame and condensation integrated boiler

Abstract

The invention discloses a water-tube type central-reverse-flame and condensation integrated boiler. The water-tube type central-reverse-flame and condensation integrated boiler mainly comprises a combustor, a shell, a boiler furnace, a front smoke box, a water tube type heat exchanger, a back smoke box and an energy saving device, and is characterized in that the shell of the boiler is in a cuboid shape, and the boiler furnace is in a cylinder shape or a waveform shape; the front end of the boiler furnace is welded to the front smoke box, and an elliptical end socket is welded to the back end of the boiler furnace; the cuboid water tube type heat exchanger is arranged below the boiler furnace, a smoke inlet in the shell side of the water tube type heat exchanger is welded to the front smoke box, a smoke outlet is welded to the back smoke box, and the snakelike fined tube type energy saving device is arranged in the back smoke box; and the boiler furnace, the front smoke box and the water tube type heat exchanger are all immersed in boiler water to form a full wet-back structure. Smoke exhausted by the boiler furnace passes through the front smoke box to enter the water tube type heat exchanger, water in heat exchange tubes is heated through the smoke, and hot water ascends through natural convection and is heated through the boiler furnace again to be drained from a water outlet tube of the boiler. According to the boiler, the central reverse flame type is adopted, the heat exchange tubes are transversely scoured by the smoke, a boiler body and the energy saving device are integrated, and the heat efficiency of the boiler is high.

AI Technical Summary

Benefits of technology

This patented technology solves problems such as increased size or complexity of existing designs for boilers due to their unique shape that allows them to absorb greater amounts of heat without increasing its overall dimensions. Additionally, it provides improved performance compared to previous methods while also being lighter than traditional types of fuel cells.

Problems solved by technology

This patented problem addressed by this patents relates to improving the efficient burning of fossil fuel for generating power without producing harmful emissions such as greenhouse gases like carbon dioxide. Gas- fired boilers have been developed with improved designs over time, resulting in better control over air quality and reducing environmental impact on their owners. Existing systems suffer drawbacks including poor recovery of waste heat when they operate at higher temperatures than necessary leading to increased operational costs associated with these devices.
