The feasibility study report of coal moisture control project Coal moisture control technology development in the past 30 years, has now developed into hot flue gas as the heating medium, dehydrated in a fluidized bed for equipment form third generation moisture control technology. The companys coal moisture control technology both in the investment cost, or in the integrated processing performance, operation and maintenance have more advantages. Through the implementation of the project, and the technical achievements to the coking industry application, not only can make the enterprise with a smaller investment to achieve energy saving effect is good and obtained better economic benefit, promote technological progress, but also strong support for scientific research units of technical achievements, form a benign circulation, thus with the development policy of national industry structure adjustment policy and related technology, achieve win-win situation. Coal moisture control (Coal Moisture Control CMC) is moisture of charging coal control process for short, is a part of coking coal for removal of water in the oven before installing, keep the moisture of charging coal stable at around 8.5% (tamping coke oven) or 8.5% (top), then the furnace coking.CMC is different from the coal preheating and drying. Coal is preheated to the coal in the furnace to decompose before starting temperature with gas heat carrier or solid heat carrier heating (150-250 ℃), when the moisture content of coal is zero, then install the furnace coking; coal drying without water control measures strictly; after drying the moisture change with coal branch moisture changes. Coal moisture control strict water control measures, to ensure that the water content of coal into furnace constant.To reduce and stability control of coal moisture through direct or indirect heating, do not pursue to maximize the removal of furnace coal moisture, and the water stability at a relatively low level,Not only can
