Condensate Return. Condensate from a steam boiler system is hot mineral free water. Strong consideration should be given to returning all usable condensate in order to minimize the use of cold makeup water which must be heated prior to entering the boiler. An added benefit will be the decreased use of chemicals and improved boiler surfaces.

The heat radiates from the hot water in the radiator(s). The water cools. Cooled water returns to the boiler via gravity or a separate pump. The cooled water flows back to the boiler to be reheated. It should be noted that hot water boilers are not the same as hot water heaters. Water heaters heat the water for your shower, dishwasher or tap water.

When enough thermal energy from the hot gases is transferred to the boiler water the overall hot gas temperature dips below the water dew point and some or all of the water becomes liquid. The energy released when water converts from a vapour to a liquid is picked up by the boiler water and results in a significant boost in efficiency.
There are approximately 1,500 coal-fired power generation units and 104 nuclear reactors in the United States. Each plant’s boiler unit will have at least two boiler feedwater pumps that increase the pressure of the condensate water and discharge into the boiler.
Stack Economizers and Condensers should be considered as an efficiency measure when large amounts of make-up water are used (ie: not all condensate is returned to the boiler or large amounts of live steam is used in the process so there is no condensate to return) or there is a simultaneous need for large volumes of hot water.
As water passes through boiler tubes, becomes steam, and is returned as condensate, it picks up ____. dissolved and particulate solids Heating the make-up water with ____ can increase the efficiency of the boiler from 2 to 4%.
Boiler Commissioning & Functional Testing - Quality Assurance Functional testing of a hot water boiler in the commissioning process can be streamlined if coordinated properly. Much of the Functional Testing Procedure can be accomplished by coordinating with the startup technician or engineer and the test and balance crew.

Prearrangement for optional three-way bypass valve for switching between Heating and Domestic Hot Water, with probe for checking remote boiler temperature, for MK 50 and MK 70 versions only. (prearrangement for DHW external circulator control, for the whole range). Time programming for boiler preparation. Siphon for draining condensation.
Steam is sent to radiators, while hot water flows to radiators or radiant heating systems. Boilers are fueled by natural gas, heating oil, propane, electricity or a biodiesel-oil blend.
In the Food industry, processing of meats & poultry requires heat and significant amounts of hot water for many of the process & cleaning applications throughout the plant. De-hiding - Meat producers use a combination of scalding and de-hair to prepare for evisceration. Carcasses are immersed in the tank that is filled with water at 136 to 140°F.

Oct 01, 2018 · Much like the return of condensate to the boiler, recovering the heat from the boiler blowdown can increase boiler efficiency. The blowdown valve is used to remove boiler water which contains soluble and insoluble solids. It helps reduce the level of dissolved solids in the boiler water to prevent the boiler scale.
Glossary Of Boiler Terms A ABSOLUTE PRESSURE - Pressure above zero pressure; the sum of the gauge and atmospheric pressures. ACCUMULATOR - (STEAM) A pressure vessel containing water and/or steam, which is used to store the heat of steam for use at a late period and at some lower pressure.

About one third of return water can be subcooled by reverse water-cooled chiller to enhance the condensation effect. The older boilers run only occasionally (peak demand, gas boiler outage). Hot water is heated by a heat pump (HP) utilizing waste heat from hydraulic oil in a stage system (HEX3).
Testing Boiler Condensate. Steam condensate is like money in the bank for boiler owner-operators. It has already been purchased and treated, making it most desirable for reuse as feedwater. The more condensate returned to the boiler, the less make-up water needed. Its heat content, when recycled back to the boiler, generates energy savings.
