As a kind of special equipment, industrial boiler is special and complex. Complete inspection can ensure the safety operation of the boiler.
The external inspection of the boiler is generally conducted once a year, the internal inspection is generally conducted once every two years, and the hydrostatic test is generally conducted once every six years.
For boilers that cannot be inspected internally, a water pressure test should be conducted every three years. The internal ...
There are many valves commonly used in atmospheric gas-fired boilers, including gate valves and stop valves of main steam valves, water supply valves, check valves, exhaust valves, etc.
When the water pump is turned on, the pressure signal is transmitted to the on-off valve of the atmospheric gas-fired boiler through the pressure pipe, the valve is opened, and the water circulation is carried out. When the water pump stops, the pressure drops, and the on-off valve is closed slowly to av...
Boiler parameters are the main indicators of boiler performance, including boiler capacity, steam pressure, steam temperature, feed water temperature, etc. Boiler capacity can be expressed by rated evaporation or maximum continuous evaporation. Rated evaporation is the amount of steam continuously produced per unit time under the specified outlet pressure, temperature and efficiency. The maximum continuous evaporation is the maximum amount of steam that can be continuously produced per unit time under the specified outlet pressure and temperature.
As a kind of special equipment, the safe operation of industrial boilers is the key point that every enterprise may pay attention to. Today, let’s talk about the normal water level in boiler operation.
During the normal operation, the steam drum water level maintains 0mm, and the allowable fluctuation range is ±30mm, with the maximum not exceeding ±50mm.
Explosion doors mainly use their own weight or strength. When it is greater than or equal to the total pressure acting on the furnace at normal pressure, the explosion-proof door is closed. When the furnace pressure changes, the total pressure acting on the explosion-proof door exceeds the weight and strength of the explosion-proof door itself, the explosion-proof door will be flushed or broken, and a part of flue gas in the furnace will be released, thus achieving the purpose of pressure relief.
The horizontal hot water boiler burner refers to the burner used in the horizontal hot water boiler, which is the most important equipment in the auxiliary equipment of the horizontal hot water boiler.
Different boiler parameters have different requirements on the PH value of boiler water. Generally speaking, the PH value of boiler water is basically between 10 and 12, in some cases, the PH value is between 9 and 11.
The boiler water film dust remover uses dust-containing gas to impact the inner wall of the dust remover or other special components, and forms a water film in some way, so that the dust in the flue gas is captured by the water film, thus purifying the gas.
