PC it the Boiler deaerators and deaerating column at prices that are acceptable not only for large enterprises but also for medium or small companies and firms.

Deaerators is a special device for removing from the water dissolved gases, which can not only hurt the quality work, but also cause an emergency situation in the workplace. In other words, with their help, is deaeration — removal of oxygen and other corrosive gases from the water supplied to the steam generators, the water supply system and a heating system. Most often, such a device can be seen in power plants, enterprises of chemical industry and those industries where you installed steam and hot water boilers. The deaerator PC Boiler, the price of which can also depend on its model, has a two-stage scheme of degassing. The first stage of the bubble, the second jet.

The principle of operation of deaerating column PC Boiler
Deaerating column PC Boiler works in the following way: subject to deaeration of the prepared water is supplied to distribution plate (upper) intake HVO, where in the future through the holes she jets flows down the spillway in intermediate plate. The intermediate drain plate is installed in the column deaerator PC Boiler to increase the residence time of the water jet in the steam space in the jet compartment, which contributes to its greater heat. It is worth noting that the PC Boiler manufactures Weir plates in stainless steel, unlike many manufacturers. Pay special attention to this!
The water in the jet compartment vent column PC Boiler heated by steam to a temperature of saturation, with a slight underheating of about 1-1,5 °C. at the same time, the ventilation jet ventilation compartment speakers PC Boiler. The main heating of water and coarse deaeration takes place directly in the jet compartment speakers PC Boiler.
Next, the liquid enters the exhaust part of the steam bypass valve, where it is still further heated by the vapor up to the saturation temperature. Steam bypass valve is designed for heating water in the column PC Boiler up to saturation temperature before serving it on the bubble sheet and to further regulate the rate of steam bubbling in the holes of the sheet. The minimum fluid velocity is calculated in column so that to prevent the failure of fluid through the bore hole of the bubble sheet, the maximum - to prevent the entrainment of water with bubble sheet column vent PC Boiler.
Propedeuse valve in the deaerating column PC Boiler works in the following way: an increase in the workload of the deaerator, the difference between the pressures P1 and P2 increases, respectively propedeuse valve is opened and this increases the flow of steam through the steam bypass valve, in addition to the bubble sheet. Thus, steam bypass valve in the deaerating head PC Boiler maintains an optimal steam flow through the bubble sheet, closing or opening, depending on the differential pressure on it. It should be noted that the steam bypass valve in the deaerating head PC Boiler are modernized and are made in such a design, which allows it to maintain optimum hydrodynamic regimes of bubbling at the entire load range of the deaerator. Passing bubble sheet, liquid, under the influence of steam, forms a dense bubble layer with intense turbulence and a maximum surface mass transfer, where the final deaeration of the water. The steam-air mixture in column deaerator PC Boiler goes through the pipe the flash steam.
The design of the column vent PC Boiler allow it to work steadily, without reducing the quality of aeration, low temperature water inlet, and also with races of pressure and flow of water in the deaerator. Deaerating column PC Boiler is very reliable in operation and internals accessible for maintenance and repair.
