Comprehensive review of water tube boilers, their types, scale formation, reduced efficiency, and maintenance solutions with specialized Mitreh solutions to increase life and reduce fuel consumption

A complete review of fire tube boilers, their types, advantages and disadvantages, useful life, scale formation, and preventive maintenance solutions using specialized chemicals is available.

Introduction to boiler types including Fire Tube, Water Tube, HRSG and Package. Applications, advantages and disadvantages of each type and a guide to optimal selection for the oil, gas and refinery industries.

Analysis of the causes of cracks in the existing shell/tube exchanger and providing solutions to prevent similar incidents. The shell/tube exchanger is used to regulate the air temperature for drying granules in silos. Due to a leak in this exchanger after 5 years of operation, the tubes were separated from the shell and the tubesheet and tube areas were subjected to non-destructive inspections. It was found that many cracks had formed in the connection between the tubes and the tubesheet on the hot air inlet side, but no defects or discontinuities were observed on the air outlet side.

Comprehensive guide to steam: saturated steam, superheated and flash + steam tables, enthalpy, applications in turbines and industry. Everything about steam from a thermodynamic perspective!

Steam boilers are mainly made of carbon steels, and the internal surface of these metals that are in contact with water must be free of deposits. Deposits have a lower thermal conductivity than metals, which causes the temperature of the metal to rise on the combustion wall side. Therefore, more fuel is needed to produce steam. Therefore, there is a need to control and wash these deposits inside the steam boiler.

Because few people can think clearly and rationally during a crisis, it is important to be prepared to respond to such situations. Emergencies can be natural or man-made, such as floods, storms, fires, releases of toxic gases, or chemical spills.

There are various types of heat exchangers in the industry, examples of which include: double-tube, plate, spiral tube and shell-and-tube heat exchangers, each of which has its own working method. Also, each heat exchanger has its own advantages and disadvantages.
