Problems solved by technology

However, because biomass fuel generally has the characteristics of uneven fuel size, high moisture content, and high ash content, its combustion process is complicated.
Due to its structural reasons, the existing hot blast stoves have incomplete fuel combustion, resulting in low thermal efficiency and prone to coking

Embodiment Construction

[0025] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0026] First of all, it should be noted that the swirl wind mentioned in this application refers to the wind with an uneven wind direction, and the wind direction of the swirl wind can change continuously during the flow process.

[0027] Such as Figure 1 to Figure 5 As shown, a hot blast stove provided in this embodiment includes a fur...

Abstract

The invention discloses a hot-blast stove which comprises a stove shell. A hearth is arranged in the stove shell and connected with a first air inlet pipe; an outlet is formed in the first air inlet pipe and located in the hearth; a swirling air generator is arranged at the outlet and used for converting air exhausted out of the outlet into swirling air; and an air blower is connected to the end, away from the hearth, of the first air inlet pipe. According to the hot-blast stove provided by the invention, as the swirling air generator is arranged at the outlet of the first air inlet pipe, swirling air can be provided into the hearth, oxygen is provided for fuel in the hearth evenly and sufficiently, and meanwhile swirling air has a good function of turning the fuel, so that the fuel in the hot-blast stove is not prone to coking or caking and capable of being sufficiently burnt.

Description

technical field [0001] The invention belongs to the technical field of combustion stoves, and in particular relates to a hot blast stove. Background technique [0002] With the development of society and the progress of technology, people pay more and more attention to the protection of the environment. In recent years, due to the increasing shortage of traditional energy sources, fuels such as coal, coke, diesel and gas will produce a series of harmful gases after burning, seriously affecting the environment and human health; and biomass fuels are inexhaustible, and The harmful gas produced in the combustion process is less than that of traditional fuels, and its development, recycling, and production have received unprecedented attention. The raw material of biomass fuel is mainly obtained from agricultural and forestry wastes. After a series of processing, they are burned and converted into biomass energy, which provides an alternative energy source for industry. [000...
