Modern Method to deterMine recovery Boiler efficiency

In a simple boiler process, the fuel and the required amount of combustion air are fed into the boiler. The fuel reacts with the oxygen in the boiler and the fluegas is drawn out. The released heat is captured to the water pumped into the boiler which transforms it to the steam that flows from the boiler.

Degassing, Feed water, Boiler feedwater treatment, Thermal

Thermal degassing. Thermal degassing (pressure degassing) of boiler feedwater requires that the water be boiling. In this state, the solubility of gases in liquids lies near zero. The mixture of condensate and fresh water is fed into the degassing dome at the top. Heating up to the boiling temperature occurs with heating steam,

The Concept of Condensing Boilers - Hydronic Heating System

The Concept of Condensing Boilers ENERGY SAVINGS AND ENVIRONMENTAL COMMITMENT Combustion is a chemical reaction with heat The products of this reaction are carbon dioxide (CO 2), and water (H 2O) in the form of steam. The water absorbs the majority of the heat generated by combustion; this causes it to change state from liquid to steam

All of the hot flue gases exit the furnace into the combustion chamber (or turn around). From there, the flue gases enter the convective sections of the boiler. Depending on the pass arrangement of the boiler, the flue gases make 1, 2 or 3 passes through the water stored in the pressure vessel.

The quality of feedwater required is dependent on boiler operating pressure, design, heat transfer rates, and steam use. Most boiler systems have sodium zeolite softened or demineralized makeup water. Feedwater hardness usually ranges from 0.01 to 2.0 ppm, but even water of this purity does not provide deposit-free operation.

Heating water with superheated steam!? - ResearchGate

If you want to heat the water with a stream of steam superheated water, at elevated pressures (superior to 15 bars), there is no problem. With relation to liquid pressure and for a heating by direct contact, the steam will then undergo a desuperheating, a condensation and subsequently a subcooling to release both sensible heat

Is Boiler a heat exchanger? - Quora

Jan 05, 2017· Since exchange of heat occurs in the Boilers, Boilers can be termed as a Heat Exchanger. But there's more to a Boiler, than just being a Heat Exchanger. In a typical Heat exchanger, heat is Shared/Exchanged between two fluids. But A Boiler generates heat through chemical reaction of the fuel, and exchanges the heat with the water to produce steam or heated water depending on

Boiler | Engaged in Thermodynamics

As the amount of water in the steam drum within the boiler decreases, the amount of heat absorbed by the water decreases, thus heating the steam. Because less water is converted to steam, the existing steam is heated and the pressure inside the vessel increases dramatically due to the offset ratio of water and steam.
