Combustor

Abstract

The invention provides a combustor and belongs to the technical field of combustion devices. The combustor comprises a base, a combustion furnace and a feeding funnel; the combustion furnace comprises a furnace body; the furnace body and the feeding funnel are fixed on the base; the feeding funnel is provided with a feeding hole and a discharge hole; a feeding device is arranged between the discharge hole of the feeding funnel and the furnace body of the combustion furnace; a fire outlet which is communicated with a combustion chamber is arranged on the external side wall of the furnace body; a fire outlet pipe which is communicated with the fire outlet is fixed on the fire outlet; one end of a fire outlet pipe is a fire outlet end which is arranged under the fire outlet; a fire spraying nozzle which is communicated with the external side wall of the fire outlet end is fixed on the external side wall of the fire outlet end; a feeding back pipe which is communicated with an end opening of the fire outlet end is fixed on the end opening of the fire outlet end; one end of the feeding back pipe is a feeding back end which is communicated with the combustion chamber; and the feeding back end is arranged under the fire outlet end. The combustor has the advantages of solving the technical problems that the fuel cannot be sufficiently burnt in the existing combustion furnace and the existing combustion furnace is easy to cause potential safety hazards such as scald and enabling the fuel to be fully combusted and being safe to use and low in production cost.

Description

technical field [0001] The invention belongs to the technical field of combustion devices and relates to a burner. Background technique [0002] With the continuous development of my country's industry, boiler manufacturing and its combustion devices play a pivotal role in promoting economic development. The combustion furnace can provide a large amount of heat energy for the boiler, so it has become a very important heat production device for people. [0003] In the existing small combustion furnaces, wood pellets are usually used as fuel, and the combustion chamber of the combustion furnace is combusted by delivering compressed granular fuel to the combustion furnace to produce heat energy. In the prior art, the combustion furnace supplies fuel to the combustion chamber through the feed branch pipe. Since the feed pipe and the combustion chamber are connected, the flame in the combustion chamber will spread into the feed pipe, resulting in The fuel starts to burn before ...

AI Technical Summary

Problems solved by technology

However, since the observation tube and the combustion chamber are connected, the flame in the combustion chamber will spread to the observation tube, causing the observation tube to become hot and hot, and the observation mirror is burnt and blackened, which is very difficult for people to observe. big security risk

Moreover, when the flame is sprayed out from the flame injection tube in the combustion furnace, the unburned fuel will also be sprayed out along with the flame, which will block the flame injection tube, and will also lead to a decrease in the combustion calorific value efficiency of the fuel.
