Embodiment Construction

[0022] refer to figure 1 , figure 2 , image 3 As shown, the high-temperature-resistant corundum grate with a single solid structure of the present invention can be made of corundum powder-based refractory materials, and can be made into multiple single blocks, multiple solids, grid-shaped assemblies, and grate-shaped overall structures. The anti-fire grate. The temperature of the backburning grate can reach 1,000 to 1,800 degrees Celsius when the boiler is running, generating strong radiant heat, so that the unburned black smoke and other combustibles in the backburning coal seam are radiated heat when they pass through the backburning grate. Burn it to achieve the purpose of high efficiency, environmental protection and energy saving.

[0023] refer to Figure 4 ,Figure 5, Figure 6 Shown is the monomer double-row entity structure of the present invention.

[0024] See Figure 7, Figure 8 , Figure 9 Shown is the monomer multi-row entity structure of the present inv...

Abstract

The invention relates to a kind of high-temperature resistant corundum reverse burning grate. It is made up of transverse and lengthways bars, the monomer is corundum solid body. The coal burns on the grate. The temperature of the grate can reach 1000-1800 deg.C, it can boost up the burning assistant and enhances the temperature of the burning house, burns the smoke and dust in the high temperature sufficiently.

Description

technical field [0001] The invention belongs to the technical field of coal-fired boilers and coal-fired furnace pits, and relates to a back-burning fire grate. Background technique [0002] The existing vertical or horizontal naturally ventilated coal-fired boilers all use water tube grates for their reverse combustion grates. The disadvantages in use are: easy overheating and fouling of water pipes, short service life; small ventilation, low temperature of water pipes. Due to the limitation of the physical characteristics of water, the temperature of the water pipe is low, resulting in a low furnace temperature, slow and insufficient coal combustion, low thermal efficiency, high black smoke concentration, and easy pollution. Existing improved technology (the People's Republic of China, patent No. 92106402.0) can arrange water pipe fire grate in layers, but still adopt water pipe fire grate, and above-mentioned deficiency still exists. The existing kilns for roasting refra...
