Boiler feed water - Lenntech

The make-up water is usually natural water either in its raw state, or treated by some process before use. Feed-water composition therefore depends on the quality of the make-up water and the amount of condensate returned to the boiler. The steam, which escapes from the boiler, frequently contains liquid droplets and gases. The water remaining

Thermal Shock in Your Steam Boiler Will Ruin Your …

In steam systems that return very little condensate, it is common to "make up" the lost water with incoming fresh water, sometimes referred to as "city water." The best practices for accepting this makeup water in a steam boiler is usually outlined in the boiler manufacturer guidelines and often includes some type of pre-treatment regimen.

Temperature of steam versus water in a boiler

2009-10-17 · How much of a difference is there in the temperature of steam in a boiler compared to the temperature of the water? Why I'm asking is to find out how critical it is that a temperature probe be immersed in the water in a boiler. I'm thinking that the temperature level can change, so does the probe have to go really low, or is

2007-7-27 · I recently purchased a condominum unit with a very old air conditioning system (1980's). A home inspection revealed a return/supply difference of only 13 degrees. We requested that a licensed HVAC contractor come to inspect the unit (in particular the return/supply temp difference) and were given a brief "it is fine" type receipt. Not very convincing to say the least.

Power Boiler Feedwater and Steam - Convergence …

The purpose of a power boiler is to create steam by applying heat energy to water. The water supply to the boiler, which is converted to steam, is called "feed water". This feed water system removes any impurities in the condensate, which is steam converted back to water, preheats and pressurizes it, then returns it to the power boiler steam drum.
