Conventional (boiler and turbine) power plants use a variety of resources such as coal, oil and natural gas as fuel to generate power. MHI group has an extensive record in meeting the global demand of conventional thermal power stations, including providing highly-efficient ultra-supercritical pressure boilers with an output of over 1,000MW. We also offer proprietary technology that enables the efficient …

Refer figure-2.1 (top) Figure 2-1: Cogeneration (Bottom) compared with conventional generation (top) If the same end use of 24 units of electricity and 34 units of heat, by opting for the cogeneration route , as in fig 2.1 ( bottom), fuel input requirement would be only 68 units …

The Joule–Brayton (JB) constant pressure closed cycle is the basis of the cyclic gas turbine power plant, with steady flow of air (or gas) through a compressor, heater, turbine, cooler within a closed circuit (Fig. 1.4).The turbine drives the compressor and a generator delivering the electrical power, heat is supplied at a constant pressure and is also rejected at constant pressure.

Back Pressure Steam Turbine is also called as Non Condensing Steam Turbine is mostly used in process steam industries or co-generation plants. The non-condensing steam turbine uses high-pressure steam for the rotation of blades. This steam then le

A boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator. A boiler or steam generator is used wherever a …

15-01-2019· Boiler in thermal power plant accumulates the steam and build up a pressure to expend it in turbine and convert thermal energy to mechanical energy. The generator which is connected to turbine converts the mechanical energy into electric energy.

Swapan Basu, Ajay Kumar Debnath, in Power Plant Instrumentation and Control Handbook, 2015. 3.6.6.1 Requirements of Condensate Polishing Unit. Boiler pressure is the key factor for determining the requirement of a CPU system (see Figure II/3.6.6-1).For the steam generator plant with low steam pressure (below 40 kg/cm 2), the requirement of a condensate polishing unit is usually avoided.Hard …

The advantage of high-pressure boilers now comes in their power density, producing twice as much steam per boiler block compared to low-pressure boilers, reducing the amount of space and resources (mostly iron/steel) needed for the same amount of steam. The only difference in cost between a 36HP and 36LP is converting 72 iron into steel.

Condensing steam turbines are most commonly found in thermal power plants. In a condensing steam turbine, the maximum amount of energy is extracted from the steam, because there is very high enthalpy difference between the initial (e.g. 6MPa; 275°C; x = 1) and final (e.g. 0.008MPa; 41.5°C; x = 0.9) conditions of steam.This is achieved by passing the exhaust steam into a condenser (called a …
