Water Handbook - Preboiler & Industrial Boiler Corrosion
Corrosion is one of the main causes of reduced reliability in steam generating systems. It is estimated that problems due to boiler system corrosion cost industry billions of dollars per year. Many corrosion problems occur in the hottest areas of the boiler-the water wall, screen, and superheater tubes.

Heat Recovery Steam Generator - an overview
Heat recovery steam generator is a high-efficiency steam boiler that uses hot gases from a gas turbine for reciprocating engine to generate steam in a thermodynamic Rankine Cycle. This system is able to generate steam at different pressure levels according to chemical process requirements (PGTHERMAL, 2009). HSRG system can use single, double

Choosing the right steam boiler for your needs - Cape
Nov 16, 2021 · For example, Maasdorp says that one of Allmech's clients in the glass manufacturing industry needed a low average steam generating capacity, but when they looked into the production process, the company realised that significant steam was required at specific intervals. This necessitated a bigger boiler size.

Boiler - Wikipedia
Fire-tube boiler Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space).This is the type of boiler used in nearly all steam locomotives.The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point.

DESIGN RULES FOR STEAM CONDENSATE SYSTEMS
Steam is produced by combusting fuel in the boiler of a steam power plant. The superheated steam is expanded to a lower pressure in the turbine generating mechanical work energy of a turbine shaft rotation, which in turn when connected to a generator produces electricity.

Chapter 12: Heating, Air Conditioning, and Ventilating
Steam heating systems are classified according to the pipe arrangement, accessories used, method of returning the condensate to the boiler, method of expelling air from the system, or the type of control used. The successful operation of a steam heating system consists of generating steam in sufficient quantity to equalize building heat loss at

Carbon dioxide corrosion is frequently encountered in condensate systems and less commonly in water distribution systems. Water containing ammonia, particularly in the presence of oxygen, readily attacks copper and copper-bearing alloys. The resulting corrosion leads to deposits on boiler heat transfer surfaces and reduces efficiency and

Legionellosis (Legionnaires' Disease and Pontiac Fever
Direct steam-type humidifiers inject boiler-generated steam directly into the air stream. These systems normally operate above 70°C (158°F), inhibiting Legionella growth. Avoid using raw steam from the central heating boiler due to contamination with corrosion inhibitors and anti-scaling chemicals.
