A condensing boiler can condense the water vapour in the flue gases and withstand the corrosive and acidic qualities of the flue gas condensate. Although most boilers can condense the flue gasses, only boilers that have heat exchangers constructed from materials able to withstand the corrosion should be used in condensing application. Condensing boilers with primary and secondary heat exchanger do not work well as they are not able to fully condense and defeat the purpose of using a condensing boiler. Also, boilers with this arrangement are prone to condensation in the primary heat exchanger at lower firing rate which can cause damage to the heat exchanger.
The most obvious use of boilers in any building, including hospitals, is typically heating for the facility. A reliable steam boiler is one of the most economical ways to provide heat across a large space, especially one with multiple floors.
One of the biggest issues related to natural gas explosions is that in the industrial world, people just don’t understand that natural gas piping repairs are different from other piping repairs.
On a steam raising boiler there are three clear applications for level monitoring devices:
1) Level control - To ensure that the right amount of water is added to the boiler at the right time.
From wood burning to pellet-firing biomass, alternative fuel boilers and solid fuel fired boilers offer environmentally friendly energy options and cost efficiencies. With the push to become less reliant on fossil fuels, alternative fuel boilers provide a way for plant managers to save money on fuel sources as well as meet tightening emission regulation standards.
If the impurities in the boiler feedwater are not dealt with properly, carryover of boiler water into the steam system can occur.
Carryover can be caused by two factors:
To prevent scale formation from low remaining levels of hardness which may have escaped treatment. Sodium phosphate is normally used for this, and causes the hardness to precipitate to the bottom of the boiler where it can be blown down.
