Technical Field

The invention relates to the technical field of combustion, in particular to a suspension grate type combustor suitable for fuels with poor flowability or easy blockage.

Background

At present, the method for burning liquid fuel or waste material mainly has 2, one is burning in a rotary kiln, the other is burning in a liquid fuel burner organization by atomizing the liquid fuel through an atomizing nozzle, the burning has the advantages of strong adaptability to oil products and insufficient burning, the lining of the rotary kiln is easy to ablate, the occupied area is large, and the investment is high. The burner adopting the atomizing nozzle has the advantages of high combustion efficiency, sufficient combustion, difficult ablation of furnace lining and relatively small hearth, and has the defects of incapability of burning liquid fuel or waste with higher viscosity, higher requirement on a supply system, need of pressurizing the fuel or the waste, and relatively complex system because of the addition of medium-pressure steam or compressed air to assist fuel or waste atomization.

The rotary kiln is a horizontal rotary kiln, generally has a high inlet and a low outlet, and the combustion materials in the rotary kiln slowly move to the outlet under the action of rotation and gravity. Burning during the movement, eventually discharging ash from the outlet, is subject to various corrosion by the fuel used, as the burning takes place in the kiln lining of the rotary kiln.

The liquid fuel burner atomizes fuel or waste material into fine particles through the nozzle, and mixes the fine particles with air for combustion, and because the structure of the nozzle is relatively complex, when burning fuel with high viscosity or easy blockage, the atomizing performance of the nozzle is reduced and even the nozzle is blocked, so that insufficient combustion or combustion failure is caused.

Aiming at the problems actually encountered in industrial production, including poor-quality waste oil, various high-viscosity waste materials, even the combustion problem of waste rubber and the like, a combustion device suitable for the conditions is urgently needed, namely, the combustion device can treat high-viscosity liquid fuel, has poor liquidity and is easy to block a traditional nozzle.
