A boiler is a steel pressure vessel in which water under pressure is converted into steam by the application of combustion. In other words, it is simply a heat exchanger which uses radiant heat and hot flue gases, liberated from burning fuel, to generate steam and hot water for heating and processing loads.
The Basics of Steam Heating by Dan Holohan If you ask a dozen people what the proper operating pressure for a steam system is, you'll probably get a dozen different answers. Most folks just follow "what they were taught" without giving much thought to the results. You see most steam systems run at ridiculously high pressures.
Steam generation fundamentals. A steam generating system has to provide a continuous and uninterrupted heat source for this conversion. The simplest steam generating equipment used to carry out this conversion is a kettle type boiler for heating a specific quantity of water. As a result of the applied heat, the water temperature increases.
From the economizer the feed water flows to the steam drum of the boiler. In the steam drum the water is well mixed with the existing water in the steam drum. This reduces thermal stresses within the steam drum. The saturated water flows next from the steam drum

In a steam power plant, power is generated by the turbine generators that utilize steam produced in the boilers. The specific design of the steam cycle and its operating conditions (primarily, the steam supply and discharge conditions) dictate the pressure, temperature and flow rate of steam required to generate the specified power output.
The water came down the hollow downcomers to enter the water tubes, which crossed the firebox. On the other side of the firebox are risers, made just like the downcomers, from the top of which the mixture of water and steam returned, through large cross tubes, to the steam drum at the top of the boiler.
