Condensation hot water boiler

Abstract

The invention provides a condensation hot water boiler which comprises a combusting chamber and a condensation heat exchanger, wherein the combusting chamber is positioned in the housing of the condensation heat exchanger; a connecting pipeline is arranged at the lower end of the combusting chamber; the connecting pipeline penetrates out of the housing of the condensation heat exchanger to be connected with a combusting machine; a smoke discharging opening is formed in the top cylinder wall of the combusting chamber; a flue gas deflecting bent pipe is connected onto the smoke discharging opening; the smoke discharging end opening of the flue gas deflecting bent pipe is formed downwards; a boiler water-supplying atomizing device is arranged on the flue gas deflecting device. The specific flue gas deflecting bent pipe and the water-supplying atomizing device are arranged, so that the high temperature flue gas and the water supplied for the boiler can be in direct contact with each other for heat exchange, and the heat efficiency can be effectively improved and the temperature of the discharged flue gas can be lowered. Therefore, the condensation hot water boiler can provide the reliable hot water for enterprises and public institutions in the aspects, such as heating, industry and bath.

Description

technical field [0001] The invention relates to the technical field of condensing boilers, and provides a condensing hot water boiler in which fully combusted high-temperature flue gas and boiler low-temperature feed water directly contact and exchange heat. technical background [0002] In order to reduce the exhaust gas temperature and improve the thermal efficiency of the boiler, the measures taken by the condensing hot water boiler are to keep the flue gas in the boiler flue as much as possible so that the flue gas can fully contact with water, and to make the water vapor content in the exhaust gas as much as possible These are effective measures to improve thermal efficiency. However, the devices for implementing these measures in the prior art have the problems of complex structure and poor effect, so that the exhaust gas temperature of the condensing hot water boiler cannot be significantly reduced in practice. In addition, there are many exhaust outlets of the conden...

Problems solved by technology

However, the devices for implementing these measures in the prior art have the problems of complex structure and poor effect, so that the exhaust gas temperature of the condensing hot water boiler cannot be significantly reduced in practice. In addition, there are many exhaust outlets of the condensing hot water boiler. There are cases where white smoke takes away more heat and the circulating water is lost. In addition, due to the unreasonable structural design of the condensing hot water boiler, it also affects the heating effect
