The vertical gas velocity is 3.5 m/s in the afterburner chamber at a thermal load of 25 Gcal/h. The off-gas at a rate of 66,000 Nm3/h leaves the afterburner chamber at a temperature of 1000°C. Heat is recovered in a steam boiler. The gases leave the boiler at 270°C. Steam is generated at 25 atm and superheated to 250°C at a rate of 34 t/h.Get Price
Creep failure is an important phenomenon for steam and chemical plants which operate at high temperatures of 450 to 550°C, boilers, ovens, gas turbines, supersonic jets, rockets, missiles, and nuclear plants all working at very high temperatures. Creep failures or ruptures are easy to identify due to the deformation (necking) that occurs.Get Price

Condensate return water treatment: These chemicals regulate the pH of the condensate from the boiler returning to the system. They also protect pipes from corrosion. Boiler inhibitors: These are all-in-one packages of chemicals that treat the boiler water to control pH, stop foaming, prevent corrosion and protect against scale and pitting.Get Price
May 04, 2016 · pH – Boiler and Condensate. pH is a measure of the acidity or basicity (alkalinity) of water on a scale running from 0 to 14. The neutral point on this scale is pH 7; values below 7 indicate increasing acidity and those from 7 to 14 indicate increasing basicity.Get Price

As a boiler generates steam, any impurities which are in the boiler feedwater and which do not boil off with the steam will concentrate in the boiler water. As the dissolved solids become more and more concentrated, the steam bubbles tend to become more stable, failing to burst as they reach the water surface of the boiler.Get Price

The value of the ratio increases almost logarithmically with increasing pressure and decreases with increasing pH. The effect of boiler water pH on the silica distribution ratio becomes greater at higher pH values. A pH increase from 11.3 to 12.1 reduces the ratio by 50%, while a pH increase from 7.8 to 9.0 has no measurable effect.Get Price
The high-pressure liquid enters a boiler, where it is heated at constant pressure to the compressed liquid (Step 2-3) and two-phase (i.e., water and steam) mixture (Step 3-4). The steam is then passed through the superheaters, where it superheated (Step 4-5). The steam is then expanded through a turbine to generate power (Step 5-6).Get Price
Failures result when the tube metal temperature is extremely elevated from a lack of cooling steam or water flow. A typical example is when superheater tubes have not cleared of condensation during boiler start-up, obstructing steam flow. Tube metal temperatures reach combustion gas temperatures of 1600F (870C) or greater which lead to tube 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. increasing boiler water pH: Even if the original makeup or feedwater pH is not low, feedwater can become acidic from contamination Get Price

In the past, the boiler feed tank systems in sugar factories had to be checked several times a day to make sure there were no sugar solution leaks. This was a very laborious process and, as continuous monitoring was not possible, monitoring results were not reliable. When a leak occurred, recovery operations were very costly and time-consuming.Get Price
Fire-tube boiler Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space).This is the type of boiler used in nearly all steam locomotives.The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the …Get Price
