WEB: E MAIL: enquiry@corponit.com nitincorporation@yahoo.com FAX : PH (O) : / THE FOLLOWING GAS FIRED POWER PLANT IS AVAILABLE FOR SALE WITH US WITH IMMEDIATE DELIVERY: 1 No. 7.8 MW Deutz (MWM) make, Gas fired Power plant as per the following technical specifications: DESCRIPTION OF THE INSTALLATION The plant consists of two DEUTZ (MWM) engines, model TBG 632 V 16 operating by natural gas. Before the connection to the gas regulator group of each motor, the natural gas passes through a newly installed Measurement and Regulation System that filters and reduces the pressure to adapt it to the motor requirements. The data of the Otto cycle gas engine, with lean mixture combustion, turbo charger, are shown in the following table: Brand DEUTZ TBG 632 V 16 Unit Power Gas Consumption Cylinders and Configuration Rotational Speed kwe kw at 100 % loading tolerance 5 % 16 V rpm Electrical Efficiency 41,4% Thermal Efficiency 44% Air Flow Inlet appr. Exhaust Gas Flow appr kg/h kg/h Gas Temperature 467 ºC Each engine operates a generator of kva electrical output. The current of each generator is sent to apart 11 kv set-up transformer.

2 Current situation of the engines : The installation has running time of the engines of h and h hours respectively. Thermal Utilization Steam generation The exhaust gas from engines were directed to heat recovery steam generators (boilers) that produce 3 t/h saturated steam at 7,5 bar using the heat produced by the exhaust gas. Steam Conditions per engine Maximum Steam Flow with Exhaust Gases from the Engine Registered Pressure Normal Operating Pressure Steam Quality Exhaust Gas Recovery Flow 3 t/h 10 bar 7,5 bar kg/h kg/h Gas Temperature of Engines 467 ºC Feed Water Temperature 95 ºC Eco-Outlet Temp.with Exhaust Gases 163,8 ºC Hot Water The thermal energy from the HT and LT coolant circuits of the engine were also used to produce kwh/engine. The total heat balance of the cogeneration plant is as follows: - Steam Production from exhaust gases at 7,5 bar 3 t/h per engine - Hot Water Production Therefore the recovered heat during the cogeneration process is : Recovered Heat Exhaust Gases kwth/engine Recovered Heat Cooling Water kwh/engine Total Heat Used kwh/engine NITIN CORPORATION 1 No. 7.8 MW Gas Fired Deutz Power Plant.

3 Total Annual Energy Balance: Running Hours per Engine Power Electricity generation Fuel Consumption Steam Produced Used Heat h 2 x = kwh kwh 2 x x 8000 = kwh 2 x 3 x = t/year kwh Electrical Installations The cogeneration electrical system entails two kva alternators, both at 11 kv 50 Hz. Engines are connected to the grid by means of a step-up transformers. For the electrical power supply of the equipment within the cogeneration plant, there is an auxiliary switchboard. This distribution board to auxiliary service supplies the following equipment: Boiler Control Panels Pumps and ventilators Process Control Panel Control Panel of the Engines Crane Bridge Air Coolers Ventilation Fans Lighting Etc.
