Energy audit for pyroprocessing unit of a new
The energy audit was performed on the pyroprocessing unit of a cement plant • An applied methodology for the thermal energy audit was presented • The potential of electrical energy production from the exhaust gases was evaluated • The economic Section Specific Audit: Detailed audit of any of the sections or equipments of plant like Crusher, Raw mill, Coal mill, Pyro section, Cement mill, Process fans, Bag Filters/houses etc It includes detailed plant audit of specific section/equipment[s] and detailed audit report of the same from cementindusneedProcess and Energy Audit Cement Plant Optimization cement plant’s total thermal energy use and Imported coal constitutes 1430% (6306Mkcals)followed by minimum contribution by both the liquid fuels 44 Share of type of Energy in cement production From the piechart in Figure 46, it is clear that in the production of cement in this plant 6775% of total energyDETAILED ENERGY AUDIT AND CONSERVATION IN A Industrial energy consumption lies between 30% and 70% of the total energy consumed in selected countries Cement production is one of the most energy intensive industries all around the world This paper deals with an energy audit analysis in a cement plant different strategies are offered to reduce energy losses Generally,Energy auditing in cement industry: A case study Modern, dryprocess cement plants with efficient configuration of grinding and pyro processing systems typically consume less than 700 kcal/kgcl thermal energy and 100 kWh/mt of electrical energy Older plants have inefficient systems, which compounded with operational and maintenance inadequacies, tend to have much higher energy consumptionCement Industry Plant Process Audits Featured
Energy Modeling of the Pyroprocessing of Clinker in a
Pyroprocessing section at the plant Abstract: Optimization of energy use in the pyroprocessing of clinker is the most important step in the modern cement industry Since the process of clinkerization consumes the largest share of the purchased energy, engineers and managers at the cement plants are constantly trying to monitor the specific pyroprocessed in the cement kiln, with gypsum The cement production process requires thermal energy (heat) for production of clinker, which is the primary ingredient for the manufacture of cement Clinker production typically occurs in kilns heated to about 1450 C Clinker production is the most energyintensive process in cement manufacturingCement Kilns: Audit Report of Two Cement Plants in 51 Grouping of Cement plants 7 52 Energy Consumption Range 8 53 Example: Normalised Baseline parameters and Target for PPC 8 54 Apportionment of SubSector Target of Energy Saving in Cement Sector 9 541 Apportionment of Target of Energy Saving in individual Cement plant 9 6 Normalization 10 61 Capacity Utilisation 11 611 Need for Cement Sector Bureau of Energy Efficiency The cement manufacturing operation for maximum cost efficiency not only requires the advanced technological design but also sound operational practices Operational Audit is an effective way for enhancing the productivity and minimising energy consumption The objectives of a comprehensive operational audit of a plant should include:OPERATIONAL AUDIT : AN EFFECTIVE WAY FOR cement industry energy and economic data were collected, and analyzed The remainder of this report is organized as follows: • Section 2 summarizes California cement industry statistics • Section 3 provides an overview of the cement production process • Section 4 presents results of interviews with cement industry customersINDUSTRIAL CASE STUDY THE EMENT INDUSTRY
