Basic Boiler Maintenance For High-Pressure Problems

What type of boiler do you have? The type of boiler can also make a difference in providing maintenance for high-pressure systems. Typically, your boiler will either be a watertube or firetube boiler. This is important because watertube boilers tend to be able to handle high pressure while firetube boilers are used for low pressure.

High Pressure Boilers: Features and Advantages ~ ME …

A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.

What Are Low Pressure Boilers? Reference.com

A low pressure boiler has both a lower design pressure and a lower operating pressure. Steam quality is determined based on the moisture level of the steam. Low pressure boilers typically produce a lower quality steam that contains more water in liquid form than does high-quality steam.

Characteristics of boiler feedwater - Lenntech

A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica, phosphates etc, in relation to working pressure.
