The case study plant has a full cement process line from mining to cement finish grinding. it has a production capacity of tons of clinker and tons of cement. the clinker produced is not sufficient to make all the required cement and therefore the plant import some clinker to meet the.The expelled hot gas needs to drive another turbine, so the exhaust is passed through a hrsg, which creates superheated steam that drives a downstream steam-turbine. the turbine can either drive a generator (combined cycle system) or just use the steam in process applications (cogeneration or combined heat and power.
The financial benefits of cement additives products . hot gas required to keep the mill at the ideal temperate use of hot gas generator historic test results show cement plants are able to increase production up to percent and decrease energy consumption by up to percent using tavero vm additives for example, a cement plant in europe was running a vrm and spraying water at.The gas fired hot air generator we manufacture is ranging from 50,000 kcal/hr to 15, 00,000 kcal/hr. the payback periods will be 2 to 10 months against oil / gas fired or electrical hot air.
The heating process is efficient because the meal particles have a very high surface area in relation to their size and because of the large difference in temperature between the hot gas and the cooler meal. typically, 30%-40% of the meal is decarbonated before entering the kiln. a development of this process is the 'precalciner'.The so3 generator is running fully automatic, providing a constant flow of so3 in air gas available for your process. the so3 generator has been developed to comply with ec machinery directive and special emphasis has been put on sil compliance, to allow an easy and safe integration into existing production.
