Energy-saving and environment-friendly gas heating and water heating boiler

Abstract

The invention relates to the technical field of waste heat boilers, in particular to an energy-saving and environment-friendly gas heating and water heating boiler. Burning pipes are intertwined outside a gas main pipe in the circumferential direction, and smoke outlets of the burning pipes penetrate through a shell of a smoke exhaust chamber and extend to an inner cavity of the smoke exhaust chamber; a smoke vent is reserved at one side of the smoke exhaust chamber, a water-steam separator is arranged above a water-steam return chamber, and the water-steam separator and the water-steam return chamber are connected through steam pipes; a gas-guide pipe is arranged on the top of the water-steam separator in a penetrating mode, a heat exchanger is connected to the tail end of the gas-guide pipe, and the heat exchanger communicates with a burning chamber through a water-guide pipe. The energy-saving and environment-friendly gas heating and water heating boiler is large in heat exchange amount and high in heat exchange efficiency, and fuel is saved.

Description

technical field [0001] The invention relates to the technical field of heating and hot water boilers, in particular to an energy-saving and environment-friendly gas heating and hot water boiler. Background technique [0002] Waste heat boiler, as the name implies, refers to a boiler that uses waste heat in waste gas, waste or waste liquid in various industrial processes and the heat generated by the combustion of combustible substances to heat water to a certain temperature. Oil-fired boilers, gas-fired boilers, and coal-fired boilers with smoke boxes and flue waste heat recovery are also called waste heat boilers. Waste heat boilers can produce hot water or steam for use in other sections through waste heat recovery. [0003] Strengthening energy conservation and emission reduction and realizing low-carbon development are important contents of my country's ecological civilization construction and the only way to promote economic quality improvement and efficiency upgrading....

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the shortcomings in the prior art, and propose an energy-saving and environment-friendly gas heating and hot water boiler. By wrapping the combustion pipe in a circumferential direction outside the gas main pipe, the water in the furnace can be heated in all directions. , increase the heating area, large heat transfer rate, high heat transfer efficiency, and solve the problems of low heat utilization rate and serious heat loss of traditional waste heat boilers
