be adequate. To achieve this, the boiler should be completely filled with treated water which contains 350-400 ppm of caustic soda, and 120-150 ppm of sodium sulfite. These chemicals must be thoroughly circulated so that all parts are protected. The water should be tested frequently enough to insure that these limits are maintained.

the steam. In high pressure boilers, therefore, silica is appreciably concentrated in the steam and this is when 'carry-over' may occur, being deposited later, on the superheaters or turbine blades. Silica entering a high pressure boiler can concentrate very quickly. An impurity entering at a concentration of 2 mgl-1 in a boiler evaporating 1500 tons of water per hour, would collect in the boiler at

Boiler Feed Water Treatment for Industrial Boilers and Power Plants
Adsorptive stripping voltammetry (AdSV) provides fast and sensitive detection of iron in process waters of the water-steam circuit (boiler feed water, makeup water, condensate) in power plants. This is achieved by adding suitable complexing agents to convert the iron …
An Engineering Guide to Modern Fuel Systems
A power generation boiler consists of an economizer, a furnace （ evapo- rator）, a superheater tube, a reheater tube, a main steam pipe, a reheat pipe, a water feed pipe, and a feed water heater tube. We manufacture various carbon steel, alloy steel, and stainless steel tubes and pipes to suit the usage conditions of these pieces of equip
