Waste Heat Recovery System

• For different cement technology and fuel conditions, our main steam pressure parameters can have a variety of options 0.7Mpa, 1.25Mpa, 1.75Mpa, etc. for the WHR project of 1000TPD-10,000TPD cement production line;
• While selecting system pressure parameters, according to cement technology and fuel conditions needed for the exhaust gas temperature, and then by selecting the smallest temperature difference, to determine the most appropriate vapor pressure, in order to achieve maximum heat recovery and do not affect cement production.
• The heat entropy of 330-200oc segments is recycled of kiln inlet boiler. You can select the appropriate boiler main steam pressure: 0.789Mpa, the corresponding saturated steam temperature is about 178oc, plus boiler heat and cold temperatures narrow point (preferable 10-30oc) after heat exchange with the exhaust gas output by steam, the temperature drop to 200oc, which can meet the needs of drying requirement of vertical mill.
• For a short time, the moisture of raw materials is large, you can open the bypass damper for introducing a small amount of high-temperature exhaust gas, mixed with the boiler outlet, increase air temperature of raw materials entering into the raw mill, to meet the drying requirements.
• Well adapted to fluctuations of waste gas temperature and flow rate in the cement kiln outlet, and meet clinker production requirements.
• Pressure steam is acting as the main steam, superheated steam condensate steam to gas turbine, steam turbine power to improve workmanship. For example: 5000t / d clinker production line, dual pressure technology can generate more than 200KW power.
• Compared with other types of thermal systems, boilers can fully absorb low-grade heat to further reduce exhaust gas temperature, creating a better working condition for subsequent equipment like kiln outlet filter.
