The need to provide boilers with high-quality feedwater is a natural result of the advances made in boiler performance. The ratio of heating surface to evaporation has decreased. Consequently, heat transfer rates through radiant water wall tubes have increased-occasionally in excess of 200,000 Btu/ft²/hr.

ZG's quality objectives will
Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam. This means that even a small percentage blowdown can represent a high mass to be blown down. Water-tube boilers tend to operate at higher pressures, usually up to 150 bar g. The higher the pressure, the greater the energy contained in the blowdown water.
Conventional wisdom teaches that high total dissolved solids in boiler water increase tube corrosion and/or fouling. Indeed, that is true. High or highly fluctuating TDS will result in low heat transfer, reduced boiler capacity and efficiency, and shortened tube life. But it can also affect steam quality.
The structure of heavy oil fired water tube boiler is arranged as drum longitudinal type "D" shape, it's quickly assembled boiler with water tubes, has the characteristics of high steam quality, sufficient output, and high thermal efficiency (97%), etc. The structure of furnace water cooling wall and convection gas pass is membrane wall, have good sealability, and effectively reduce
Boilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube material. A buildup of deposits inside the tubes will produce an insulating layer which inhibits the ability of the water to remove the heat from the tube.
– Horizontal or gently sloping boiler tubes – Boiler tubes of high heat flux • Metal oxide deposits provide an ideal place to concentrate dissolved solids • "Free" caustic alkalinity in the bulk boiler water will concentrate in the deposits and cause caustic gouging on the metal surface under the deposit Boiler Water-Side Internals

High-Quality Steam Generation. For example, not only are water tube boilers smaller and more efficient than fire tube boilers, but they are also far safer. With modular steam boilers, there is an added benefit of transferring steam output to other units while one is receiving maintenance. 3. …
Boiler feed water quality is limited owing to problems of (1) scaling, (2) corrosion, and (3) foaming. In order to avoid these problems, the quality guidelines shown in Table IV have been adopted. Data in Table IV show a major difference between cooling water and boiler feed water quality constraints, in that boiler feed water has a strong relationship between water quality and the pressure of
