Abstract

The invention discloses a coal charge conveying device, a boiler system and a coal charge conveying method and belongs to the technical field of pulverized coal boiler combustion. The coal charge conveying device comprises a clay storage cabin, a feeder, a coal conveyor belt, a weighing mechanism, a raw coal bunker and a control mechanism, wherein the clay storage cabin is used for storing clay; the feeder is arranged on the downstream side of the clay storage cabin; the coal conveyor belt is arranged on the downstream side of the feeder and is used for conveying a coal charge; the weighing mechanism is arranged on the coal conveyor belt; the raw coal bunker is arranged on the downstream side of the coal conveyor belt and is used for accommodating mixed coal charge and clay; and the control mechanism is electrically connected to the weighing mechanism and the feeder and is used for controlling working parameters of the feeder according to a weight measured by the weighing mechanism. Byadding natural clay with proper components into the coal charge, a problem that an existing boiler is agglomerated and is stained severely is solved, and the boiler burns high alkali coal safely andeconomically in a long period.

Description

technical field [0001] The application belongs to the technical field of pulverized coal boiler combustion, and in particular relates to a coal material conveying device, a boiler system and a coal material conveying method. Background technique [0002] my country has rich reserves of high-alkali coal, one of its typical representatives is Xinjiang high-alkali coal. Among them, the Zhundong coalfield has a predicted coal reserve of 390 billion tons, which is currently the largest integrated coalfield in my country. High-alkali coal generally has strong slagging and contamination characteristics, which greatly threatens the safety and economy of boilers burning high-alkali coal. [0003] At present, it is difficult for power plant boilers to burn Zhundong high-alkali coal safely, and they often mix low-sodium coal whose factory price is several times higher than Zhundong high-alkali coal, especially when the volumetric heat load is greater than 70kW / m 3 Or a boiler that us...
