Tips. Having said this, it is necessary to be mindful of the following when heating with saturated steam: Heating efficiency may be diminished if steam other than dry steam is used for process heating. Contrary to common perception, virtually all of the steam generated from a boiler is not dry saturated steam, but wet steam, which contains some non-vaporized water molecules.Get Price
May 02, 2000 · condensation occurs in systems where carbon dioxide is a problem. Keep in mind that the The impurities found in the makeup water will build up in the boiler as the water turns to steam leaving most impurities behind. There are known maximum limits for these impurities, which can and will be surpassed without proper blow down. Get Price
upon the ratio of boiler feedwater makeup to returned condensate and the operating pressure of the deaerator. Deaerators use steam to heat the water to the full saturation temperature corresponding to the steam pressure in the deaerator and to scrub out and carry away dissolved gases. Steam flow may be parallel, cross, or counter to the water flow.Get Price
The quantity of steam which the boiler generates, usually measured in kg/h. For selecting a blowdown system, the most important figure is usually the maximum quantity of steam that the boiler can generate at full-load. When the above information is available the required blowdown rate can be determined using Equation 3.12.5Get Price

The function of the steam trap is to return the collected water in the steam pipe to the boiler due to partial condensation of steam. The steam is not allowed to escape and automatically returned to the boiler. Construction: A steam trap is a disc or short solid pipe nipple having a small hole.Get Price
Steam blanketing is a condition that occurs when a steam layer forms between the boiler water and the tube wall. Under this condition, insufficient water reaches the tube surface for efficient heat transfer. The water that does reach the overheated boiler wall is rapidly vaporized, leaving behind a concentrated caustic solution, which is corrosive.Get Price
concentrations, steam quality can be impaired. In addition, hardness salts can precipitate from the boiler water to form sludge and eventually scale, which deposits on the internal surfaces of the boiler. The result: a serious loss of boiler efficiency, and possibly boiler failure.Get Price
The successful operation of a steam heating system consists of generating steam in sufficient quantity to equalize building heat loss at maximum efficiency, expelling entrapped air, and returning all condensate to the boiler rapidly. Steam cannot enter a space filled with air or water at pressure equal to the steam pressure.Get Price
