Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure but, at pressures above this, it is more usual to speak of a steam generator. A boiler or steam generator is used wherever a source of steam is required

Boiler Fuel Consumption Calculation--ZBG

For the calculation of boiler fuel consumption, firstly, determine the specifications and boiler steam production, and the actual enthalpy increment of the boiler is calculated from the steam pressure and steam production. Secondly, the required heat is calculated according to the efficiency of the boiler ( Fuel heat), and calorific value of fuel (per kilogram of fuel can produce heat), that can calculate the required

How much water is required to produce 1 kg of steam? -

May 23, 2017· If yes, then it required more than 1 kg of water. Other than desuperheater requirement, boiler has tendency of leakage, approximately 2-5 % of steam produced. Thus, water required is the sum of steam produced, leakage, desuperheater requirement, and water requirement for blow down.

The water is then directed to the scrubber (second stage deaeration) where the water is violently scrubbed to remove the final traces of oxygen. The steam acts as a carrier gas, to expel the removed oxygen out the vent. The deaerated water is then ready for use by the boiler, at saturated temperature and with oxygen levels at .005 cc/liter.

Boiler Feed Water - an overview | ScienceDirect Topics

Because the process requires steam generation, a good water source is essential. For boiler feed water, the raw water should not have total hardness exceeding 250 ppm. Excessive hardness in water, even with use of a water softening plant, will lead to scaling, which reduces boiler efficiency considerably. Apart from the quality of the water, an uninterrupted supply is essential, otherwise the process will be

Industrial Steam Boiler,

Steam boiler is a device used to create steam by applying heat energy to water. A boiler incorporates the furnace and drum, furnace used for burning the fuel and generating heat. The generated heat is transferred to water to make steam, is the process of boiling, the produced saturated steam will be used for industrial production and other usage.

Boiler Feed Water Treatment for Industrial Boilers and

In the steam boiler industry, high purity feed water is required to ensure proper operation of steam generation systems. High purity feed water reduces the use of boiler chemicals due to less frequent blowdown requirements (reducing blowdown frequency by as much as a factor of 10). Lower blowdown frequency also results in lower fuel costs.

Chapter 16 - Steam Purity | SUEZ

In the modern water-tube boiler, separation of the steam-water mixture entering a relatively small steam drum is a complex process. For every pound of steam generated, as many as 15-20 lb of water may circulate through a drum. As a result, 99.97% or more of the circulating water must be removed from steam to ensure the desired steam purity.
