Engineering Timelines - Richard Trevithick - High pressure steam
The first of Trevithick's high pressure engines, a steam whim working expansively at 172kN per sq m (25psi), was begun at Cook's Kitchen mine in 1800. It had a 480mm diameter cylinder with a 1.52m stroke and was still working in 1870. To cope with the higher pressure, he designed a wrought iron cylindrical boiler with internal "tube and fireplace".

Thermal Engineering Notes [With PDF]
High Pressure Heater(s) Use one or more high pressure feed water heaters to raise the temperature of feed water from de-aerator outlet temperature to the required boiler economizer inlet temperature. The heater drains are cascaded from heater to heater, back to the de-aerator in a fashion similar to the heater drain system for the low pressure heaters.

Steam Rankine cycle is known as one of the main power-generating cycles, which consists of four key devices, namely a boiler (heat exchanger), a steam turbine, a condenser (heat exchanger), and a pump, as illustrated in Fig. 28. This cycle needs heat input for the boiler either by burning fossil fuels, such as oil, coal, and natural gas, or by
