THE RATIONAL POSITION OF A GAS TURBINE IN A HIGH-PRESSURE BOILER SYSTEM

The efficiency of a marine power plant with a high-pressure boiler was investigated using the simple plant arrangement and a given cycle process. It was found that a high efficiency of the plant can be achieved on the basis of the efficient arrangement of the gas-air and steam-water cycles. The insertion of an external water economizer into the cycle as well as an increase in the temperature before the gas turbine in a system without an external economizer were found to increase or decrease plant efficiency or not to affect it at all, depending on the air pressure rate in the cycle. A formula for the maximum efficiency of a plant with an external economizer was derived as a function of the temperature before the gas turbine. For the most common air pressure rates (between 3 and 6), a temperature increase before the gas turbine was found to increase the efficiency of the plant with an external economizer and to decrease the efficiency of a plant without an external economizer.
