WHY WE NEED BOILER WATER TREATMENT FOR POWER PLANT

Did you know that when water is converted to steam it expands in volume over 1,000 times and that it travels a down a steam pipe at over 100 kilometres/hr? Steam is a great way of moving energy and heat around a site from a central boiler house to where it is needed, but without the right boiler feed water treatment, a steam-raising plant will suffer from scale formation and corrosion. At best, this increases energy costs and can lead to poor quality steam, reduced efficiency, shorter plant life and an operation

Proedure of douing Boiler Performance Test

The performance test in a boiler evaluates the practically achievable boiler efficiency. Performance tests are also carried out to prove boiler guarantees. As guarantees involve contractual conditions, the procedure involved are more elaborate than the test for evaluating performance.
Conducting a boiler performance test can be for understanding the current level of performance of the boiler, for any trouble shooting of the boiler for performance deviations, and for proving the performance guarantees. These entire three requirements can be met by the procedure adopted for performance guarantee testing. Before

how much water forms during combustion ?

When you burn fossil fuels or hydrocarbon fuels, the exothermic combustion reaction of Hydrogen in the fuel and Oxygen in the air produces water. This water goes out as vapour along with the flue gas. In coal firing, moisture in the coal augments the water quantity.

The quantity of water produced is much more than the steam cycle make-up quantity in fossil fuel power plants. If one can economically capture this water and use it for steam cycle make up and other utility applications in the power plant, it can greatly

Boiler Tube Failure due to Opening a Drain Valve

We had just erected and commissioned a circulating fluidized bed boiler for an industrial plant in Southeast Asia. The boiler was a state of the art CFBC and almost the largest boiler in the region at that time. It was capable of producing nearly 400 tons per hour of steam for power generation and utility purposes, firing coal and biomass with superheated steam at a pressure of 140 bar and temperature of 540°C.

what amount Air is Required for Burning the Coal?

The most important requirement to burn coal is the correct quantity of air. This article explains how to calculate the correct quantity of air.Coal is the most widely used fuel source used to produce electricity. Air is necessary to provide oxygen for burning coal. It is the chemical reaction between carbon in coal and the oxygen in the air that produces heat energy.

Function of Circulating Fluidized Bed Boiler

Circulating Fluidized Bed combustion has given boiler and power plant operators a greater flexibility in burning a wide range of coal and other fuels. All this without compromising efficiency and with reduced pollution. How does the boiler work with this technology?

In the olden days blacksmiths used to heat the iron by placing it on a bed of coal. Bellows provide air to the coal from the bottom of the bed. Fluidized Bed combustion is something similar to this.

Major events in Boiler Commissioning

Purpose of steam blowing

Cleaning by steam blowing is carried out essentially for steam circuits (i.e for steam generating boilers, steam heated exchangers, steam turbine upstream piping or other steam lines). Due to problems of condensation of steam or draining of condensate, this type of cleaning has to be used with the utmost care, as it can pThe purpose of blowing or cleaning the steam lines prior to starting up a new unit is to remove

HOW TO INCREASING BOILER EFFICIENCY AND HEAT RECOVERY

10 tips that can be used to educate plant and facility managers on how to maximize boiler performance:

1.Maintain, Maintain, Maintain – following manufacturer recommendations on annual boiler maintenance is the easiest way to ensure the boiler will continue to run efficiently.
2. Proper Water Treatment – if water treatment is not done correctly, you will see a loss in heat transfer ability due to particulates clogging up internal boiler tubes. A deaerator can be used in most applications to increase water temperature and remove most of the particulates from the water.
