A boiler economizer (also known as an economizer) are mechanical devices intended to reduce energy consumption or perform a useful function such as preheating a fluid. A boiler economizer is essentially a heat exchanger that makes a system more energy efficient by taking enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler – hence recovering more useful enthalpy and improving the steam boiler’s efficiency.
The most obvious use of boilers in any building, including hospitals, is typically heating for the facility. A reliable steam boiler is one of the most economical ways to provide heat across a large space, especially one with multiple floors.
There are two types of burners for industrial steam boilers, depending on how they control the mixture of air and fuel at the key point in the boiler's operation, which is the generation of combustion.
Three-pass steam boilers are so-called because the combustion gases that are produced inside them in the burner go round a circuit that has three parts before leaving it:
When they reach a certain size, industrial steam boilers are installed in a boiler room which is necessary to ensure safety while they are operating as pressure equipment, in accordance with local regulations.
The pharmaceutical sector is an area that requires the highest quality steam for its processes, known as clean steam, instead of other industrial steams. Some processes in this sector even need the highest level of quality - pure steam, which involves even stricter steam purity requirements for use in the sterilization of raw materials and pharmaceutical products at high temperatures.
A steam boiler is a water containing vessel which transfers heat generated by a fuel source into steam, which is then piped and directed to points where it could be used while running industrial equipment. The basic idea here is to convert water to steam using a source of heat.
