supercritical boiler. To do this, I'll have go back to our sub-critical experience. Figure is a arrangement Of circuitry in a sub-critical natural circulation boiler. Note that the economizer and superheater are once. through, as would be a reheater which is not shown. In the furnace, however, recirculation is employed.

The boiler circulating pumps are required to function in the start-up or low pressure conditions but when the pressure goes above critical pressure then these are stopped and once through circulation is provided by boiler feed pump. Advantages of Once through boilers: The following are the advantages of once through boilers for large thermal

Once-through boilers are able to produce steam at higher pressures and temperatures than drum boilers. In thermal power plants, raising steam conditions (pressure and temperature) can enable efficiency gains in power generation equipment, allowing an operator to reduce its fuel consumption and CO 2 emissions. Mitsubishi Power delivered its first supercritical pressure once-through boiler in 1968, and followed up in 1981 with delivery of the first supercritical variable pressure once-through

critical once through boiler. XI and XII plans, large capacity addition is only possible with the setting up of supercritical units of more than 660MW. With the growing environmental concerns on emissions, there is an urgent requirement to use the most advanced technology currently available in the world.

Haycock and wagon top boilers. For the first Newcomen engine of 1712, the boiler was little more than large brewer's kettle installed beneath the power cylinder. Because the engine's power was derived from the vacuum produced by condensation of the steam, the requirement was for large volumes of steam at very low pressure hardly more than 1 psi (6.9 kPa) The whole boiler was set into brickwork

Although the concept of once-through circulation has been extensively used in fired boilers, the application to combined cycles of a large scale is rather new. Once-through circulation is required at very high pressures, including supercritical conditions, for which there is a possible advantage in terms of the overall plant efficiency.
