high pressure boilers: meaning, types, characteristics .

High Pressure Boilers: Meaning, Types, Characteristics .

The feed water from the hot well is pumped by the feed pump through the economiser and preheated water is supplied to the boiler drum. The water is heated up by the hot gases flowing in the upward direction, which are later exhausted through the chimney high in the atmosphere to reduce air pollution.

Difference Between Low- and High-Pressure Boilers | Hunk

High-Pressure Boiler Definition High-pressure boilers will heat steam above 15 psi and water at pressures that exceed 160 psig. Temperatures in high-pressure boilers will exceed 250 degrees F. Because of the elevated pressure at which these boilers operate, they need to be monitored to ensure safety at all times.

Characteristics of boiler feedwater - Lennte

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. ...

water treatment for industrial steam boile

Water treatment for industrial steam boile

The volume of blowdown is determined by the boiler type, operating pressure and water treatment quality of feed and makeup water. In high quality boiler water, levels of suspended and total dissolved solids (TDS) are down to a minimum. This will minimize blowdown volume and hereby reduce energy loss, as the temperature of the blowdown liquid is ...

Stephen Hall, in Branan's Rules of Thumb for Chemical Engineers (Fifth Edition), 2012. Introduction. Boilers are essentially shell-and-tube heat exchangers, with water being boiled to steam or transformed to high pressure hot water. Heat is generated by burning a fossil fuel; the combustion gas can be ducted around tubes containing the water (water-tube boiler), or the hot gas can pass inside ...

Boiler Water Treatment Basic - Boilersin

When BFW boiler feed water enters the boiler, the elevated temperatures and pressures cause the components of water to behave differently. Most of the components in the feed water are soluble. However, under heat and pressure most of the soluble components come out of solution as particulate solids, sometimes in crystallized forms and other times as amorphous particles.

Treated raw water is mixed with potable water and pumped to the boiler feedwater treatment system. The system is designed to remove 99% of the dissolved minerals and provide high-purity water to the boiler. The mixed water flows through a reverse osmosis plant operating at a recovery of 80% and an average salt rejection of 95%.

Pre-heating the feed water to achieve an ideal boiler feed water temperature will allow the boiler to run most efficiently as the heat input required to raise the temperature of the water up is reduced. The difference between 140°F and 180°F in boiler feed water temperature equates to about a 3-4% difference in boiler efficiency. Feed water ...
