If you’re seeking out new ways to reduce your operational expenses, investing in a shell and tube heat exchanger to begin recovering otherwise wasted heat is an excellent place to start. To learn about the best way to incorporate a waste
Chat OnlineAn electrostatic precipitator (ESP) is a filterless device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit.. In contrast to wet scrubbers, which apply energy directly to the flowing fluid medium, an ESP applies energy only to the particulate matter being collected and
Chat Online(ESP) in a cement plant. With a very short response time it allows a safe burning process control, fewer shutdowns of the ESP and lower environmental impact. When does it get dangerous in an esP? Dust particles get loaded in the electric field of the esP and separated. esP acts as a source of ignition at high CO levels. In practice, explosions

Chat OnlineFor a narrow cross-current heat exchanger with no heat losses fed with clinker at 1300°C, the temperatures of clinker and secondary air are: Reference to the data sheets on fuels shows that the air needed for combustion is usually in the range 335-345 kg per GJ of energy, or say 380 kg allowing a 10% excess. This means that an efficient kiln
Chat OnlineThe heat exchanger has been designed in such a way that it can be run for 24 hrs. The Air-to-Air Heat Exchanger reduces both the temperature and the dust loading of the excess gas to the dust collecting system,thereby lowering the gas volume to be handled and increasing the life of the filter bags.
