The waste gas from a sponge iron plant exits at a temperature of around 200-300 C. A lot of sensible heat is lost with these gases. This heat is utilized to preheat the air entering to kiln. Further, the waste gas at reduced temperature is used to cool hot sponge iron which is previously carried out by water.
A heat recovery system could increase the efficiency of the cement plant as well as reduce the amount of CO2 emissions to the environment by lowering the temperature of the exhaust gases.
output waste heat power generation plant at the Ssangyong Cement South Korea Tokai plant. This covered about 30% of factory power consumption, contributing to a reduction of about 170,000 tons of CO2 per year. u We delivered a waste heat recovery power generation equipment for a coke oven, which was constructed in the ARCELOR－MITTAL－TUBARAO
The plant incorporated several improvements over the Huntorf one, including a waste heat-recovery system that reduces fuel usage by about 25%. The system has a rated capacity of 110 MW, from a roughly cylindrical salt cavern 300 m deep and 80 m in diameter (volume 5.32 million cubic meters); it supports pressures from 45 to 74 bars.
Waste Heat Recovery Power Plants, contribute significantly, to the electrical energy saving (to the tune of 25%). The reduction in CO 2 emission, makes it environmental friendly. Installation of the waste heat recovery plant has to be tackled as a system approach, rather than considering cement plant and WHRPP operations, independently.
remaining waste heat is converted into electricity. Waste heat recovery system: The waste heat available in the exhaust gases can be recovered and used for drying the moisture in the raw material and coal or for generating power. In addition to the plan of reducing of energy consumption in cement production process, the recovery waste heats can
b) Upset conditions occurring in the plant due to heat recovery c) Availability of space d) Any other constraint, such as dew point occurring in an equipments etc. After identifying source of waste heat and the possible use of it, the next step is to select suitable heat recovery system and equipments to recover and utilize the same. 3.
Jun 01, 2018· 2. Waste heat recovery systems. Waste heat recovery methods include capturing and transferring the waste heat from a process with a gas or liquid back to the system as an extra energy source .The energy source can be used to create additional heat or to generate electrical and mechanical power .. Waste heat can be rejected at any temperature; conventionally, the higher the temperature,
Mar 10, 2011· These cases are then compared with the existing waste heat recovery system of the plant based on coal consumption, operating and capital costs, profit, and payback period. It is found that both cases are better than the existing heat recovery system of the plant. However, case-2 is selected as the best heat recovery option.
Jun 01, 2012· Highlights Present work deals with two design modifications proposed for sponge iron plant. First design accounts for preheating of kiln air using waste gas exiting from ESP. For second design water is heated using hot sponge iron to preheat rotary kiln air. A model is developed to compute coal demand of process based on different factors. For each modification economic and operability
Steam generated from the 38 TPH waste heat recovery boiler is received in 12 MW steam turbine which will also be connected with proposed AFBC boiler for captive power generation. 1. Waste Heat Recovery Boiler The Waste Heat Recovery (WHR) based Captive Power Plant is installed at Rana Sponge site to utilize the heat content of flue gases coming
Sustainability advantages of the new plant. The manufacturing is based on 100% renewable energy. All melting and heating is done by electric powered furnaces. All internal transportation is done by electrical vehicles. The heat recovery system in the building reduces the energy consumption by 50 60%. All cooling systems are closed loops.
Overview. The Kalina Cycle ® Power Plant installed at the Kashima Steel Works, successfully demonstrates the thermodynamic advantages and the robust performance of the Kalina Cycle ®.At the Kashima Steel Works, the Kalina Cycle ® is able to recover thermal energy from the cooling water discharged by the converter gas duct of the steel plant, and generate electricity.
Sponge Iron Works presently has a capacity of 120,000 MT per annum with actual production for 2004-05 at 95943 MT. OCL proposes to come up with a Captive Power Plant (CPP) of 14MW capacity running primarily on waste heat energy with minor contribution coming from DRI kiln coal waste (like coal char, coal fines) and coal washery rejects.
