Abstract

This invention provides a coal burning furnace and additive in the domain of heat engineering. There is heat protection layer outside the furnace and the far IR reflection layer inside the furnace. The under-part of the inside furnace sets grate and the up-part forms the burning coal layer. The under-part and inside furnace consist the gas-supplying waste-out tune and the up-part of the burning coal layer forms burning heat supplying tune. The burning coal additive is added to the burning coal. The heat protection layer outside the furnace protects heat well and the inside far IR reflection layer can reflect the transferring heat to radiation heat so as to improve the heat utilization. The additive of the burning coal can let the coal burn efficiently and improve the burning rate and heat productivity. This furnace can be used to the industrial burning coal sinter, bake and calcinations.

Description

Technical field [0001] The invention proposes a coal-fired kiln and coal-fired additive for heating in the thermal engineering field. Background technique [0002] Before the present invention was proposed, the outer side of the furnace body used for heating was usually provided with an insulation layer, and the inner side was provided with a lining layer made of refractory materials. Since the outer insulation layer was usually made of ordinary insulation materials, the insulation effect Poor; the refractory lining provided on the inner side can only play a role of fire resistance, without heat reflection. Therefore, this kind of kiln has a large heat loss and wastes energy. [0003] The coal that provides the heat source for the kiln is usually burned directly, and the coal cannot be fully burned, resulting in low fuel utilization and low thermal efficiency. Summary of the invention [0004] In order to overcome the shortcomings of large heat loss in existing kilns and insuffi...
