Full-fuel cyclone furnace

Abstract

A full-fuel cyclone furnace comprises a furnace body; a water jacket is arranged on the furnace body; a liner is mounted in a hearth; a gap is formed between the liner and the inner wall of the water jacket; water outlet pipes are arranged at the top of the liner; the bottom of the liner is communicated with that of the water jacket through a connecting pipe; water inlet pipes are arranged at the top of the water jacket; a plurality of inclined grooves are formed in the inner wall of each of the liner and the water jacket; the liner takes the shape of a cone which is wider in upper part and narrower in lower part; arc-shaped roofs sunken in the liner are respectively arranged at the bottom and the top of the liner; and a sunken arc-shaped roof is arranged at the top of the hearth.

Description

technical field [0001] The invention relates to a hot water production boiler, and in particular provides an all-fuel cyclone furnace. Background technique [0002] Most of the hot water production boilers (water jacket boilers) in the past technology can only use the same type or similar type of fuel as the heat source due to structural limitations. In order to ensure the supply of hot water and improve the heating efficiency, the inner tank in the furnace is usually Enlarge the production, increase its superheated surface area and volume, and improve heat utilization efficiency. The disadvantages are: the volume of the furnace body will also increase, it will take up more space during installation, and more consumables will be used in production, which will increase the production cost and waste space and resources. It will bring a lot of inconvenience; moreover, when the volume of the inner tank becomes larger, the amount of water contained will also increase, resulting ...

Problems solved by technology

The disadvantages are: the volume of the furnace body will also increase, it will take up more space during installation, and more consumables will be used in production, which will increase the production cost and waste space and resources. It will bring a lot of inconvenience; moreover, when the volume of the inner tank becomes larger, the amount of water contained will also increase, resulting in the inconcentration of the utilization of fuel heat energy, and the need to increase the fuel consumption; the water inlet of the hot water production boiler in the past technology is usually located in the At the bottom of the furnace body, when in use, condensed water droplets (commonly known as "sweating") will be generated near the water inlet pipe and the water inlet of the inner tank due to temperature difference. After the water droplets condense and drip on the fuel, it will affect the combustion effect of the fuel, and It will lead to uneven temperature distribution of the inner tank and affect the absorption, conduction and conversion of heat energy, which is a harmful phenomenon
