An 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

(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

For 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
