Electric Boiler Heaters for Power Generation - Watt

In power generation facilities that use steam, the steam drives the turbine. The higher the pressure, the more effectively the steam can move the turbine. To achieve this, an electric boiler heater is used in a closed vessel. The pressure vessel starts with water, which the boiler heater converts into steam. Using a closed vessel makes steam ...

Sep 03, 2019· The water had then dripped down onto the control box, making a mess of the self-adhesive labels on it. Luckily, there’s been no damage to anything in the control box. I don’t think it’s water from the boiler as there’s no sign of water leaking from anywhere (including the primary HE) and system pressure is rock-solid at 1 bar.

Using Reverse Osmosis for Boiler Pretreatme

Pretreatment 44 Disadvantages of RO as compared to a softener boiler pretreatment program include: x Increased electrical costs. x If acid pretreatment is used, acid handling will be required. x Product water flow rate is pretty much fixed while ion exchange can manage variable flows. x An antiscalant may be necessary upstream of the RO. x With polyamide (PA) membranes, chlorine must be removed

Carbon dioxide attack in boilers - Lennte

In boiler systems, corrosion resulting from carbon dioxide is most often encountered in the condensate system. Because feed water deaeration normally removes carbon dioxide from the boiler feed water, the presence of the gas in condensate is typically due to carbonate and bicarbonate decomposition under boiler conditions.

Silica removal from water - Finishi

Aug 19, 2009· 2002. A. Silica can be removed from raw water easily with standard demineralization techniques. Normally silica is present in a weak acidic form. Ion exchange will remove this as long as the anion resin is the strong base type. Silica in deionized water can easily be reduced to 20-50 ppb.

silicon | Properties, Uses, Symbol, & Facts | Britanni

At red heat, silicon is attacked by water vapour or by oxygen, forming a surface layer of silicon dioxide. When silicon and carbon are combined at electric furnace temperatures (2,000–2,600 °C [3,600–4,700 °F]), they form silicon carbide (carborundum, SiC), which is an important abrasive.

The deposit of silica in boiler water which occurs is as follow: Analcite (Sodium alumina silicate - Na2O.Al2O3.4SiO2.2H2O) is formed as result of the aluminum content in boiler water through feedwater. Aluminum which is usually delivered is aluminum that is used in pre-treatment in which less supervision occurs in its implementation.

scaling and slag formation in boile

Scaling and Slag Formation in Boile

Fouling is a phenomenon where the hot flue gases and the ash precipitate and settle down in the places where the flue gases exit the boiler. This layer which is formed reduces the gas flow into the Selective Catalytic Reduction tubes. This can result in poor effluent treatment of the gases. Fouling is generally removed by soot blowers.
