Environment-friendly gasification counter-flow combustion water heater

Abstract

The invention discloses an environment-friendly gasification counter-flow combustion water heater. The environment-friendly gasification counter-flow combustion water heater comprises a combustion chamber, a heat exchange chamber and a gasification chamber. The combustion chamber is horizontally arranged, and both the gasification chamber and the heat exchange chamber are vertically arranged above the combustion chamber to form a gasification section type combustion U-shaped furnace structure. The bottom of the gasification chamber and the bottom of the heat exchange chamber are connected with the combustion chamber through a first channel and a second channel respectively. The position, close to the first channel, of the inner side of a top plate of the combustion chamber stretches downwards to form a turbulent flow baffle. Positions, corresponding to the gasification chamber and the heat exchange chamber, of the bottom of the combustion chamber are respectively provided with a slag pit. A fuel inlet is formed in the top of the gasification chamber. A grate is arranged at the bottom inside the gasification chamber. A gasification agent supply opening close to the grate is formed in the gasification chamber. An included angle alpha is formed between an outlet of the gasification agent supply opening and a horizontal line and is larger than or equal to 10 degrees and smaller than or equal to 90 degrees. The environment-friendly gasification counter-flow combustion water heater is simple in structure, convenient and quick to operate, high in combustion efficiency and small in environment pollution, and investment cost and operation cost are reduced.

Description

technical field [0001] The invention relates to a water heater, in particular to an environment-friendly gasification countercurrent combustion water heater which can be widely used for energy-saving heating in industrial drying, agricultural greenhouses, independent buildings, industrial workshops, public venues and rural households. Background technique [0002] A water heater is a device used to heat water. In the past, there were defects such as serious flue gas pollution, low thermal efficiency, difficult to control combustion, and large hidden dangers; some water heaters that have appeared in recent years mostly adopt structures such as furnaces with water pipes, although the thermal efficiency has been improved. However, the structure of the furnace is relatively complex, the requirements for fuel are high and single, and the operation and maintenance are cumbersome, which increases the investment cost and operating cost.

In the past, there were defects such as serious flue gas pollution, low thermal efficiency, difficult to control combustion, and large hidden dangers; some water heaters that have appeared in recent years mostly adopt structures such as furnaces with water pipes, although the thermal efficiency has been improved. However, the furnace structure is relatively complex, the requirements for fuel are high and single, and the operation and maintenance are cumbersome, which increases the investment cost and operating cost.
