Definition of the tph meaning in boiler
When a steam boiler is continuously operated for a long period of time, the amount of steam generated per hour is called the evaporation amount of this boiler, and is usually used in tons per hour (t/h or tph).
A steam boiler is a steam device that uses heated energy or other thermal energy that is converted by the combustion of a fuel to heat the feed water to obtain specified parameters (temperature, pressure) and quality. 1tph means that the boi...
The boiler manhole-lids are mounted from the inside of the boiler so that the boiler pressure will help to keep them tight. Hence the manholes have to be elliptical in shape to make it possible to take the lid out from the boiler.
The change of heating pressure of natural gas will affect the normal operation of the boiler, resulting in anoxic combustion, deflagration, peroxide combustion, tempering and other phenomena. Then, what factors are generally related to the gas supply pressure of natural gas boilers, and how much should it be?
Gas supply pressure of boiler
The natural gas supply pressure of the boiler is mainly related to the tonnage of the boiler, and its general principle is:
If it is a gas boiler wi...
There are many factors that affect the safe operation of the boiler, including the boiler feed water. Adopting the boiler water supply system that meets the standard can avoid some failures and ensure the service life of the boiler. Focusing on boiler industry for more than 30 years, ZOZEN Boiler has accumulated rich project experience, and summarized some auxiliary equipment mainly included in boiler water supply system, hoping to be helpful to everyone.
Boiler water supply system main...
Sulfur dioxide is a common sulfur oxide, which dissolves in water to form sulfurous acid. When oxidized in the presence of PM2.5, it will quickly and efficiently generate sulfuric acid and cause acid rain. Therefore, the concentration of sulfur dioxide in boiler flue gas directly affects the environment, and is valued by many parties.
How is sulfur dioxide produced in boiler?
The principle of how sulfur dioxide is produced in boilers using different fuels is different. Sulfur in solid ...
Tap water or water with a lot of impurities will cause the magnesium ions and calcium ions in the water to form some white precipitates when heated at high temperature, causing scaling problems and reducing the heat transfer efficiency of the boiler. Boiler operation safety brings hidden dangers, even shutdown.
The specific reason why softened water must be used in hot-water boilers is that it will not produce scale in the process of use, so that potential safety hazards of boilers can ...
Before coking and boiling, check boiler parts detailedly. Inspection items are as follows:
1. Before coking and boiling, chain grate should be cold test run again and continuous running time shall not be less than 24 hours.
2. Ignition door can be opened flexibly, coal gate can be lift and dropped conveniently, coal gate left and right side is of the same distance to grate, and ensure the material layer thickness on both sides of the furnace is equal. If distance is not equal, it can be adjust...
1. After boiler body, economizer, air pre-heater, dust collector, etc are in place and installed, connect FD fan, ID fan, etc according to drawing and then connect corresponding flue gas duct. After fan in place, alignment between foundation and equipment base should be conducted with parallels. Fan position alignment should center on a shaft, central elevation deviation and vertical and lateral central line positional deviation should be 10mm or less and fan spindle should be in level state. Th...
