Abstract
The invention provides a novel kiln-head combustion device of a dry-process cement rotary kiln, comprising a central oil gun channel, a central air channel, an inner cyclone channel, a pulverized coal channel, a coal gas channel and an outer cyclone channel which are sequentially sleeved-connected from inside to outside; the coal gas channel is arranged on a combustor and is connected with a booster fan, and the booster fan is connected with a coal gas cabinet. A use method for the novel kiln-head combustion device comprises the following steps that: waste coal gas is desulfurated, conveyed to the coal gas cabinet via the coal gas channel, boosted via the booster fan, conveyed to a coal injection tube in a novel dry cement production line, and mixed and combusted with pulverized coal to perform clinker calcination. The novel kiln-head combustion device provided by the invention has the advantages of being high in thermal efficiency and low in use cost.
Description
Technical field
The invention belongs to the technology of producing cement field, particularly the cement produced with the dry method combustion control technology.
Background technology
Coal gas and coal dust mixed combustion calcination of cement clinker are in cement in China industry beyond example still also; Cement industry calcined by rotary kiln clinker all adopts coal dust to calcine; Because the rotary system calcination of cement clinker all has requirement to heat force intensity, the length of flame and the shape thereof of flame; Use coal dust can reach the requirement of rotary system to flame; But the flame behind the use coal gas then can not reach the requirement of rotary system to it, so the producer that my company is bold in innovation with the professional production burner through technological demonstration carries out exchange of technology, has customized a cover burner according to the specification requirement of my company; Accomplish coal gas and coal dust mixed combustion through this cover burner, rotary system draws wind, feeding and corresponding technological operation control to carry out the calcining of clinker.Can reduce the energy consumption and the production cost of clinker after this technological invention utilization greatly, can save about 30000 tons of standard coal every year, ton grog production cost descends 10 yuan at least, brings huge economic benefit and social benefit to company.
Summary of the invention
The present invention is intended to overcome the defective of prior art, provides a kind of thermal efficiency high, new type nonaqueous cement rotary kiln end burner and method for using thereof that cost is low.
