Petroleum Conservation Research Association (PCRA) awarded a project to demonstrate the energy conservation measures in Pulverized Coal Fired Rolling Mill at Mandi Gobindgarh in May, 2006 which includes:
§ Improved furnace design
§ Coal pulverizing system
§ Pulverized coal burners
§ Insulation of furnace
§ Waste heat recovery system
The project stands completed in all respects.
The status in respect of execution of various components is as under:
1. Furnace Design: The Council designed the furnace with proper emphasis on the functions of three different zones – preheating, combustion and soaking zones. The furnace was properly insulated by designing the optimum thickness and adopting the best specifications and material. As a result, the industry has been able to achieve consistently a target production with considerable savings in fuel consumption and reduced heat losses. The furnace has been visited by various industrial owners, NISST, UNDP engineers and PCRA engineers who have appreciated the efficiency of the furnace.
2. Pulverizer: The Council analyzed the problems inherent in the existing pulverizers and got the pulverizer modified by increasing the hardness of the material, choosing proper alloys and also through re-engineering in terms of number of hammers and size of hammers and the speed of the drive system. Earlier results of pulverization, as got tested from a reputed lab, had revealed that hardly 1 % of the coal could be pulverized finer than 200 mesh, but with improved design and materials, we could pulverize the coal to the fineness of 75 micron, 80% of which passing through 200 mesh. It has resulted in better combustion which was at once visible through the color of the flame, faster combustion rates and distinctly lower scale losses. The improved design of the pulverizers is now being sought by a number of industries.
3. Burners: Earlier the burners were not designed and a simple pipe 4” dia was used as burner for feeding coal mixed with air into the furnace. The burner has now been designed with proper arrangements both for primary and secondary air and also the arrangements are made for providing air at the proper pressures. This has gone in a big way in improving the combustion and control over the percentage of excess air which has now been restricted to less than 20%.
4. Recuperator: Presently, none of the re-rolling mills is preheating the combustion due to unsuccessful designs of the recuperators tried by the industry so far. The Council analyzed that primarily these recuperators were loaded underground and no maintenance was carried out. The pipes were never cleaned periodically. The expansion joints were not provided for. The pipes of the recuperator, therefore, got warped out and the recuperator used to get defunct. All these defects were removed in new design (shell & shell type recuperator) which was laid above ground with proper insulation and with arrangements for maintainace. It has been possible to preheat the combustion air to a temperature of 200-250oC resulting in improvement in the combustion process and reduction in coal consumption & scale loss.
5. Instrumentation: Interaction was carried out with a number of instrumentation experts and finally ABB Experts were hired to design the instrumentation system with inbuilt provisions for control of air with the temperature in the furnace. The best possible instrumentation has been procured and got fabricated. As a result, the industry has been able to regulate the volume of combustion air and its pressure in the reheating furnaces with the resulting reduction in scale losses and wastage of fuel.
The Energy Audit of Pushpa Gujral Science City (PGSC), Kapurthala was carried out by PSCST in Oct-Dec 2011. The scope of work includes energy audit of various electrical energy intensive equipments such as pumps, motors, transformers, DG sets, HVAC systems, Lighting, etc.
The data collected with regard to each equipment was analyzed for identifying the scope of energy conservation. The study concluded that there is a scope of 28% electrical energy saving per annum (Rs. 25.44 lacs) with capital expenditure of Rs. 10.25 lacs on implementation of all the energy conservation measures. The final report indicating energy conservation measures, cost benefit analysis, payback period etc., was submitted to the PGSC in December, 2011.
The Holy Bein originates from a ‘Bouli’ in Dhanoa village near Dasuya in Hoshiarpur district and flows towards Sultanpur Lodhi in a zigzag way traversing a distance of nearly 160 km and merges into the Sangam of rivers Beas and Sutlej. With the rapid urbanization, the sewage from towns and villages started polluting the Bein.
Government of Punjab had constituted Technical Committee to restore the ecology of Holy Bein. PSCST was providing all the technical/secretarial back up support to the Project Coordinator to coordinate the various activities of the project. Now this project stands transferred to Punjab Pollution Control Board, Patiala. The progress achieved during the period is as under:
Ministry of Environment and Forests, Govt. of India had sanctioned a project on “Industrial Pollution Abatement through Preventive Strategies- Waste Minimization Studies and Air Pollution Control in Cupola Furnaces in Smalkha, Distt. Panipat (Haryana)” in 2005 to demonstrate energy efficient cupola furnace integrated with air pollution control device in one unit in the State of Haryana. The demonstration units was set up at M/s Bhart Iron Foundry, Smalkha, Haryana. The beneficiary reported increase in metal coke ratio from 9:1 to 13:1 with economic gain of Rs. 5.00 lacs per annum on account of reduction in coke consumption. The unit was able to achieve the emission norms as prescribed by State Pollution Control Board.
Department of Science and Technology, GOI had sanctioned a project on “Demonstration of energy efficient cupola furnace integrated with air pollution control device” in 2007 for setting up of 5 demonstration units of energy efficient cupola furnace integrated with air pollution control device in the State of Punjab. The demonstration units were set up at M/s R.A. Enterprises, Batala, M/s AVR Foundry & Engineering Works, Batala, M/s Challenger Machinery Company, Amritsar, M/s Santokh Singh & Sons, Phagwara and M/s Indian Agricultural Industries, Goraya. The beneficiary reported economic gain of Rs. 2-5 lacs on account of reduction in consumption of coke, lime stone and energy besides achieving pollution levels as per prescribed norms of State Pollution Control Board.
The above said project was sanctioned by DST, GOI in 2003 to design, develop and evaluate low cost technologies such as karnal technology, stabilization pond, aerated lagoon and oxidation ditch for the treatment of domestic sewage in rural areas. These technologies were demonstrated at Talwara Distt. Hosiarpur, Madhopur Distt Fatehgarh Sahib, Ulana Distt. Patiala and Alisher Distt. Sangrur.
A common effluent treatment plant having capacity of 35 m3/day was set up at Ramdaspura, Phillour, Distt. Jalandhar in 2001 for 40 small scale vegetable bag tanning units with financial assistance from Ministry of Environment and Forests, GOI and Punjab Pollution Control Board. The waste minimization measures were adopted by the individuals units by dedusting of salted hides and better soaking techniques to minimize the total dissolved solids in the effluent. The effluent from the site of individual unit was being transported to the site of CETP by small tankers. The CETP consists of Equalization Tank, Anaerobic filter, Aeration tank, Secondary clarifier & Sludge drying beds. The CETP was able to meet the discharge standards as prescribed by Punjab Pollution Control Board.
The feasibility studies for setting up of CETP based on nickel and chrome recovery had been carried out in 500 electroplating units at Ludhiana during financial year 2003-04. After detailed study, it has been recommended that waste minimization measures be implemented in each industry. The ion exchange columns would be set up in each industry to adsorb the nickel and chrome metals. The treated effluent after ion exchange would be of DM quality which would be recycled back for rinsing operations. The columns after their exhaustion would be transported to the CETP sites for the recovery of nickel sulphate and chromic acid and the fresh columns will be supplied to the industry as replacement of the exhausted columns. The effluents being generated during metal recovery would be treated conventionally.
Central Pollution Control Board, Govt. of India had awarded a project on “Comprehensive Industry Document: Development of Emission Standards and Good Practices for Electric Arc Furnaces and Induction Furnaces in SSI Sector: NIT” in 2003. During the study, the process details as well as the details of existing pollution control measures in around 100 induction furnaces and 16 electric arc furnaces located in various regions of the country were studied. The emission monitoring studies of induction and arc furnaces located in different regions having the best containment-cum-pollution control system were carried out to establish the design data and to evaluate the performance of existing pollution control technologies. After detailed study of process and emission monitoring, workable emission standards which can be economically achievable has been drafted for electric arc and induction furnaces. The draft emission standards were approved by Central Pollution Control Board and are under notification by the Ministry of Environment and Forests, Govt. of India.
Punjab Pollution Control Board, Patiala had awarded a project on “Techno-Economic Feasibility Study for examining the necessity of providing a covered shed / enclosure around mechanical drier in dry rice shellers for abatement of pollution” in 2011. During study, rice shellers located in various clusters of the State were visited and interaction was made with consultants / machinery manufacturer. After detailed study, it was recommended that rice shellers after taking the suction from dust generating sources such as unloading area, elevators, pre-cleaner should provide cyclones followed by bag filter for the cleaning section to control the air pollution. Further, bag filter is recommended for driers (tray type as well LSU type). It was recommended that two demonstration units, each for LSU drier and Tray drier be set up to establish the technology before its replication at a wider scale.
