What is a boiler

Boiler Boiler is a device used to produce steam. This steam can be used to spin the turbine or heat some furnaces. In boilers that work in power plants, it is super heat due to the need for higher steam pressure. The water in this boiler passes through the pipes that are enclosed between the flames of the burner, but in smaller boilers the steam will be saturated and in these burners the flame is inside the pipe and the water is around the pipe. a The boiler consists of several parts, which you will see a brief description of:

1. Dual burners
2. Water glass: Indicates the water level inside the boiler
3. Manometer: Indicates boiler pressure
4. Electrical switchboards and equipment
5. Warning: If the pressure inside the boiler rises when a part does not work properly
6. Pump: These boilers use a pump with a high flow rate and a medium head of the screw type, which has an electric motor as an actuator.
7. Chimney: To release the burned gases in the combustion process
8. Underwater: Outlet from the bottom of the boiler to remove sediments deposited in the bottom of the boiler
9. Heat sensor: Since the steam produced is saturated and the temperature and pressure are always proportional, instead of using a barometer, which is difficult at high pressures, they use thermal sensors using the principle that each temperature indicates a certain pressure.
10. Safety valve: If in rare cases all safety stations as well as alarms do not work properly due to a defect, if the pressure exceeds its legal limit, the valve will open and reduce the pressure by removing some of the steam inside the boiler. 11 . Trap: A unit that collects condensed steam and is also called a water trap. Water supply for the boiler: The main fluid used in the boiler is water. This fluid must be prepared and entered into the boiler in stages. The main parts of water supply are:
11. Industrial water source such as deep wells
12. Sand filter: collects solid particles suspended in water, which is composed of sandy, siliceous and rocky layers. The valves in this section and the next filter are designed in such a way that after working hours and getting dirty, the water flow can be passed through it in reverse to be cleaned.
13. Hardener: Hardener is used to separate the two elements calcium and magnesium. If these two elements are not separated from the water, the same thing happens in the boiler that happens in the kettle. In fact, sediments reduce the surface area between water pipes and water, and more energy is used to produce a certain amount of pressure. In addition to costing the production line, cleaning also stops the production line. This section consists of two tanks. It can not be directed to the sewer because the resin will be lost. After the second tank, we use it as a reduction tank. There is salt water in this tank. The reactions are performed as follows: the following is done by combining resin and magnesium. It is hard to get water now, but there are still problems to get into the boiler
14. Water-soluble oxygen that oxidizes the pipeline.
15. The low temperature of the water that casts doubt on the boiler at high temperature. To solve the above problems, a regulator is used, which is a tank containing hard water produced from the previous stage and part of the steam produced by the boiler by pressure enters it. In addition to raising the temperature of the water, the available oxygen can be released in the form of a bubble. The available water can be used by the boiler, which feeds the boiler with a high flow pump. This supply can also be automatic and if the boiler sensors do not detect enough water level inside the boiler, they can feed to the steering pump or turn on the pump manually by the pump operator.
