Embodiment 1

[0015] in such as figure 1 In the shown embodiment 1, a kind of garbage fuel for smoldering stoves comprises wooden garbage block 1 and flame-retardant particle 2, and described flame-retardant particle is the sand of particle size 0.3 to 1 millimeter, and the total volume of flame-retardant particle is wood 8% of the total volume of the rubbish block, the flame-retardant particles are scattered and bonded to the outer surface of the wood waste block, forming a flame-retardant isolation layer that automatically falls off when the wood waste block burns, and the flame-retardant particles are outside the wood waste block The distribution area of ​​the surface is 70% to 85% of the outer surface area of ​​the wood waste block. The woody waste blocks in this embodiment may be woody wastes with a block structure such as treated branches, tea seed shells, and crop straws.

Embodiment 2

[0017] The flame-retardant particles in Example 2 are loess, and the total volume of the flame-retardant particles is 15% of the total volume of the woody waste block, and the outer surface of the woody waste block is also bonded with combustion-supporting particles 3 (see figure 2 ), the combustion-supporting particles are charcoal particles with a particle size of 0.3 to 1 mm, the combustion-supporting particles are located between the flame-retardant particles of the flame-retardant isolation layer, and the distribution area of ​​the combustion-supporting particles and the flame-retardant particles on the outer surface of the wood waste block is 75% to 95% of the rubbish block outer surface area, all the other are identical with embodiment 1.

Embodiment 3

[0019] The woody waste block in Example 3 is an extruded block structure, and the outer surface of the woody waste block is bonded with combustion-supporting particles with a particle size of 0.3 to 1 mm. The combustion-supporting particles are wood chips, and the rest are the same as in Example 2.

[0020]When the fuel of the present invention is used in a smoldering furnace, the flame-retardant isolation layer on the surface of the woody garbage block can play a certain flame-retardant isolation effect between the woody garbage pieces on the one hand, thereby reducing the burning speed of the woody garbage piece, making it Meet the requirements of smoldering furnaces; on the other hand, the flame-retardant particles that constitute the flame-retardant isolation layer can automatically fall off from the wood waste blocks when the wood waste blocks are burned, and the fallen flame-retardant particles can be automatically filled into the space between the wood waste blocks. In t...

Abstract

The invention discloses refuse-derived fuel for a smoldering furnace, which comprises wood refuse blocks and flame-retardant particles, wherein the total volume of the flame-retardant particles is 8-15% of the total volume of the wood refuse blocks; the flame-retardant particles are spread and consolidated on the external surfaces of the wood refuse blocks to form flame-retardant isolating layers which can automatically fall off during combustion of the wood refuse blocks; and the distribution area of the flame-retardant particles on the external surfaces of the wood refuse blocks is 70-85% of the area of the external surfaces of the wood refuse blocks. Thus, the problems that naked fire is prone to appear in the smoldering process of biomass fuel in the prior art, the conversion efficiency of the fuel in the smoldering furnace is greatly reduced accordingly and safety accidents may be caused are effectively solved. The fuel disclosed by the invention has a stable smoldering process, is high in fuel conversion efficiency and favorable in safety, and has high practical value.

Description

technical field [0001] The invention relates to the field of fuel technology, in particular to a waste fuel for smoldering furnaces suitable for smoldering furnaces. Background technique [0002] In the prior art, a large amount of organic waste such as tree branches, tea seed shells, and crop straws is generally not used as fuel because of its low calorific value of combustion, and becomes garbage or is directly incinerated, which not only pollutes the environment, but also causes a waste of resources Therefore, some people process biomass such as crop straws into pellet fuels with high calorific value for daily life. The traditional production method of biomass fuel particles is to crush and dry raw materials such as crop straws and wood processing wastes, and then directly compress them into block-like solid fuels with special briquetting machinery and equipment for use. The essence of this processing method is to increase the density of biomass through pressurization, o...
