Boilers and Boiler Safety - Texas Department of Licensing

Jul 01, 2021 · A hot water supply boiler means a boiler designed for operation at a pressure not exceeding 160 psig or temperatures not exceeding 250 degrees Fahrenheit at or near the boiler outlet if the boiler's: heat input exceeds 200,000 BTUs per hour; water temperature exceeds 210 degrees Fahrenheit; or nominal water-containing capacity exceeds 120 gallons.

Plant Engineering | Maintaining boiler safety

Whether caused by low water or poor boiler water quality, potentially dangerous steam explosions can occur when overheated pressure parts suddenly fail under high pressure. A steam explosion in a boiler house can, in seconds, produce ambient conditions of intolerable heat and reduced oxygen levels below survivable limits.

Water Handbook - Preboiler & Industrial Boiler Corrosion

Low-Pressure Steam and Hot Water Heating Systems. Hot water boilers heat and circulate water at approximately 200°F. Steam heating boilers are used to generate steam at low pressures, such as 15 psig. Generally, these two basic heating systems are treated as closed systems, because makeup requirements are usually very low.

Boiler Feedwater - an overview | ScienceDirect Topics

Boiler feed water quality is limited owing to problems of (1) scaling, (2) corrosion, and (3) foaming. In order to avoid these problems, the quality guidelines shown in Table IV have been adopted. Data in Table IV show a major difference between cooling water and boiler feed water quality constraints, in that boiler feed water has a strong relationship between water quality and the pressure of

CHAPTER 39 BOILER WATER TREATMENT

The pressure and design of a boiler determine the quality of water it requires for steam generation. Municipal or plant water of good quality for domestic use is seldom good enough for boiler feed water. These sources of makeup are nearly always treated to reduce contaminants to acceptable levels; in addition, corrective
