Suspension combustion type boiler

Abstract

The invention discloses a suspension combustion type boiler which comprises a boiler body. A combustion chamber is arranged in the boiler body. An evaporation heating surface is arranged over the combustion chamber. A smoke discharging part is arranged on one side of the upper end of the combustion chamber. An ignition device used for ignition is further arranged in the combustion chamber. A feedpipe is included and penetrates to the combustion chamber from the outer portion of the boiler body. A conveying screw is coaxially arranged in the feed pipe. A feeding motor is arranged at the tail end of the feed pipe to be in transmission connection with the conveying screw. A feeding hopper is arranged on the upper side of the feed pipe. An air supply opening is arranged in the combustion chamber and is connected with an air supply fan on the outer portion of the boiler body through an air supply pipe. An ash collection trough gathered downwards is arranged in the direction of the lower end of the combustion chamber. The lower end of the ash collection trough is connected with an ash discharging pipe. An ash discharging screw is coaxially arranged in the ash discharging pipe. An ash discharging motor is arranged at the tail end of the ash discharging pipe to be in transmission connection with the ash discharging screw. An ash discharging opening communicating with the interior of the pipe is arranged on the lower side in the direction of the tail end of the ash discharging pipe. The suspension combustion type boiler is especially suitable for rice hull and rice bran powder typefuel.

Description

technical field [0001] The invention relates to a boiler, in particular to a suspension combustion boiler. Background technique [0002] Boiler fuel combustion uses air for combustion, and fuel combustion is often insufficient. There are relatively mature suspension combustion technologies in the market, but they are all aimed at fuel oil or coal powder, and fuels such as rice husk and bran powder are inconvenient to use. [0003] The invention proposes a suspension combustion boiler, which is especially suitable for fuels such as rice husk and chaff powder, and can make the fuel stay in the combustion chamber for a long time so that it can fully contact with the air and burn fully. Contents of the invention [0004] The purpose of the present invention is to propose a suspension combustion boiler, which is especially suitable for rice husk and bran powder fuels, which can make the fuel stay in the combustion chamber for a long time, so that it can fully contact with the a...
