Problems solved by technology

When the temperature reaches above 300°C, the damage to the downstream equipment along the route is particularly obvious, and the oxygen content of the flue gas is difficult to control
[0003] In addition, when using a hot smoke furnace or fluidized fluidized furnace, the calorific value of coal combustion is too high, the block degree is strict, and the heat loss is too large, the thermal efficiency can only reach about 30-40%, which causes too much waste of resources and cannot be effectively The use of low calorific value resources
The hot smoke furnace or fluidized fluidized furnace must be used continuously during the production practice, so that the production time can only be limited to 24 hours per day, and the special requirement of only 8-16 hours per day cannot be realized.

Abstract

The invention relates to a device for converting low-calorific value fuel into clean thermal energy and belongs to the technical field of thermal energy devices. The device is high in technical grade and capable of intercepting burning dust contained in a heated environment, intercepting rate can reach 95%, flue gas oxygen content can be controlled to be below 3%, and coal slime with calorific value as low as 2000-3000 kcal can serve as bunker coal. According to the device, automatic operation is achieved, online monitoring of oxygen content can be achieved, and the device can be popularized, can especially be applied to relevant equipment in the industries such as metallurgy, coal chemical engineering and building, and has broad market prospects.

Description

technical field [0001] The invention belongs to the technical field of heat energy devices, and in particular relates to a clean heat energy device suitable for conversion of low calorific value fuels. Background technique [0002] Most of the coal slime drying heating systems at home and abroad use industrial hot smoke furnaces or fluidized fluid furnaces for heating. In the production practice of traditional hot smoke furnaces or fluidized fluidized furnaces, there must be dust in the airflow flue gas, especially in the temperature-loaded state, there will be dust particles that are burned, commonly known as sparks. When the temperature reaches above 300°C, the damage to the downstream equipment along the route is particularly obvious, and the oxygen content of the flue gas is difficult to control. [0003] In addition, when using a hot smoke furnace or fluidized fluidized furnace, the calorific value of coal combustion is too high, the block degree is strict, and the hea...
