How to Destroy a Boiler -- Part 3

Pulling A Vacuum. When boilers are designed to operate at very high pressures, they are not designed to operate under even the slightest vacuum. A potential vacuum is created when a boiler is shut down. As the unit cools, the steam condenses and water level drops, which allows the pressure to drop.

The atmospheric steam engine as energy converter for low

The steam condenses, creating a near vacuum and the atmospheric pressures drives the piston downwards. After the piston has reached the lowermost point, the exit valve is opened in order to eject condensed and injected water. A counterweight or a slight excess pressure of the boiler then moves the piston upwards again for the next working stroke.


Boiler accessories including the flue gas economizer are also commonly used as an effective method to recover heat from a boiler. Key Components of Boilers are:-Burner – The burner is the component of boiler that provides the heat that heats the water of system. The fuels used can be natural gas or oil.

Pressure Vessels

A large amount of potential energy can exist as a pressure difference, and correct design of pressure vessels is an integral part to plant safety. As such, there are codes and standards guiding all aspects of using them. In North America, the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME BPV Code) is used.

Everything you need to know about low temperature heating

Suitable heating boilers and elements. If you have decided to go for low temperature heating, you cannot use just any heating boiler or heating elements. An LTH boiler or heat pump is indispensable. A heat pump will set you back more than an LTH boiler, but then again, it is also the most energy-efficient option.

Evaporator (marine)

The advantage of the flash distiller over the compound evaporator is its greater operating efficiency, in terms of heat supplied. This is due to working under vacuum, thus low temperature, and also the regenerative use of the condenser coils to pre-heat the seawater feed.
