Our unique resources of coal-based energy in the current society has increasing scale.Some data from the enterprise to the analysis that the energy-saving potential of the Rotary kiln have a lot of room for development. Small businesses and large enterprises comprehensive energy consumption per ton of steel 200 kg of standard coal, cement Rotary Kiln cement production accounts for 75% of total energy consumption per ton, advanced and efficient small cement Rotary kiln cement 1.4 times the energy consumption. Our 50,000 tons / year of ammonia still accounted for 55% of the small total, by and large, than the comprehensive energy consumption per ton of product differentiation ammonia around 300 kg medium-sized coal.And energy are closely related to our statistics, measurement, assessment systems, and the low level of information, serious losses and waste.So now this model makes the development of energy-saving Rotary kiln direction.
