If the impurities in the boiler feedwater are not dealt with properly, carryover of boiler water into the steam system can occur.
Carryover can be caused by two factors:
To prevent scale formation from low remaining levels of hardness which may have escaped treatment. Sodium phosphate is normally used for this, and causes the hardness to precipitate to the bottom of the boiler where it can be blown down.
A steam boiler is a water containing vessel which transfers heat generated by a fuel source into steam, which is then piped and directed to points where it could be used while running industrial equipment. The basic idea here is to convert water to steam using a source of heat.
For a boiler to operate stably and efficiently, all links must be properly coordinated without making mistakes. For gas-fired boilers, it is necessary not only to have softened water treatment facilities, but also to carry out regular sewage discharge, which cannot be ignored.
If the impurities in the boiler feedwater are not dealt with properly, carryover of boiler water into the steam system can occur. This may lead to problems elsewhere in the steam system, such as:
The thermal oil heater, also called organic heat carrier boiler, provides heat energy for production by heating the heat medium oil. It can realize the high-temperature and low-pressure heating without constant water supply. What are the characteristics of the thermal oil heater?
There are many skill indicators involved in the operation of oil-fired boiler, some of which are variables. We must master the relationship between variables and working effect of oil-fired boiler to realize better regulation.
Here load means, amount of steam drawn from the boiler. So when the load increases, the specific volume of the steam in the boiler increases reducing the pressure. This inturn demands for more feed water and more amount of fuel to be burnt. So, for any boiler there will be a feed water level control system put in place to measure the water level in drum. As and when the level of water in the drum reduces, the controller sends a signal to the feed water pump to start and stops when the desired water level is reached. This way the steam generation continues to maintain the desired pressure.
