Apr 12, 2020 · What is a boiler? A boiler is a steel pressure vessel in which water under pressure is converted into steam by the application of combustion. In other words, it is simply a heat exchanger which uses radiant heat and hot flue gases, liberated from burning fuel, to generate steam and hot water for heating and processing loads.Get Price
• Low-pressure boilers are designed to withstand a maximum of 15 psig steam or a M.A.W.P. 160 psig water. The boilers can be classified according to the following criteria. According to flow of water and hot gases: 1. Water tube. 2. Fire tube. In water …Get Price
Boilers are heating-system components designed to generate steam or hot water for distribution to various building spaces (Figure 9.18).As water cannot be used to directly heat a space, boilers are only used in central systems where hot water is circulated to delivery devices (e.g., baseboard radiators, unit heaters, convectors, or AHUs).Get Price
Simultaneously, the loss of the steam bubble from the water surface briefly creates a crater on the water surface. Water rushes in from all sides to fill this crater, colliding at the center of the crater. Thus boilers should be operated at a pressure closer to the design pressure to deliver higher quality of steam to the process as well as Get Price

Corrosion in boilers is due to the following reasons (1) Dissolved oxygen : This is the most usual corrosion causing factor. In boilers, oxygen is introduced through the raw water supply. Water usually contains about 8 ppm of dissolved oxygen at room temp. As the water is heated; the dissolved oxygen is set free and the boiler starts corroding.Get Price
Sep 17, 2021 · DISSOLVED GASES. Oxygen and CO2 even in trace amounts as low as 5 ppm (parts per million) will cause major corrosion damage over time. Dissolved oxygen will react with carbon steel throughout the feedwater piping, economizers, and boiler, causing oxygen pitting and eventually leaks. Take every opportunity for internal inspection of your boiler, economizer, and …Get Price

Boiler efficiency is a measure of the goodness of the chosen process and equipment to transfer combustion heat to the heat in steam. Boiler efficiency can be defined as the ratio of the useful heat output to the total energy input. (3.1) η = Q abs Q in. where. η is boiler efficiency.Get Price
A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.Get Price
In the case of internally fired boilers, the furnace is located inside the boiler shell. For example, Cochran, Lancashire boiler, etc. 3. Fire-tube boiler and Water-tube boiler: In the fire tube boilers, the hot gases are inside the tubes and the water surrounds the tubes. For Example, Cochran, Lancashire boiler, etc.Get Price

(2) Lowering of boiler safety : Due to scale formation, over-heating of boiler is to be done in order to maintain a constant supply of steam. The over-heating of the boiler tube makes the boiler material softer and weaker and this causes distortion of boiler tube and makes the boiler unsafe to bear the pressure of the steam, especially in high-pressure boilers.Get Price
