Stoving-free smoke-eliminating sulfur-fixing briquet for boiler

Abstract

The stoving-free smoke-eliminating and sulfur-fixing briquet for boiler consists of bituminite as main component as well as ferric oxide, magnesium oxide, potassium sulfate, sodium hydroxide, sodium nitrate, aluminium sulfate, magnesium chloride and water. It needs no stoving and thus has less investment in equipment. It has both hot and cold strength, and high smoke-eliminating and sulfur-fixingeffect.

Description

1. Technical field: [0001] The invention belongs to a molded coal, in particular to a molded coal for a drying-free, smoke-eliminating and sulfur-fixing boiler. 2. Background technology: [0002] Existing briquette production mostly adopts organic liquid binder and coal powder to mix and form, and after forming, it is dried by special drying equipment to make briquette products. The briquette produced by the existing drying process requires a large investment in equipment, a considerable amount of fuel coal is consumed during drying, and the self-pollution is serious, the heat intensity of the finished product is low, and the binder cost per ton of briquette is high. , due to the collapse of the briquette, the amount of dust carried in the flue gas increases. It does not meet environmental protection standards when burned. 3. Contents of the invention: [0003] The technical problem solved by the invention is to provide a drying-free, smoke-eliminating and sulfur-fixing ...
