One of the most important industrial installation equipment is the boiler, which has steam production operations for industrial use and some installation systems. The boiler is actually an energy transmission or conversion system in which energy lies in fossil fuels such as gas, diesel or mazot is converted to thermal energy. This device contains a closed combustion chamber in which the liquids are under high temperature and pressure and are converted to steam with strong pressure.
How the Boiler Functions
steam both directly through fuel consumption (coal, combustion of gas, gasoline, wood, etc.) or using clean energies such as solar, nuclear, etc., and indirectly such as: recycling heat Coalition in processes or even equipment (gas turbines).
in general the boilers are divided into the following two categories:
Fire boiler in pipe or fierce (Fire Tube)
Water water in the pipe or water tube
, of course, using clean energies such as solar energy In the relevant equipment (nuclear reactors) it can be produced in large comparison of Super Heat steam.
repair and service of boilers
In the process of repairing the boilers, paying attention to the constituent structure as well as periodic inspections can help the life of this important and vital industry equipment. Famco Industrial Group, as an engineering and expert organizational organization in the field of repair and service of boiler types, has been able to have a regular and targeted policy to restore and revitalize this important equipment. Proper Boiler repair and service is crucial in terms of safety and operation. In general, boiler repair includes the following:
Decluenction of the interior and other parts in contact with the fluid
de -depletion and massaging from the combustion chamber and boiler pipes
Main furnace or repairing it
Return Furnace
🔻 Replacement or replacement Problem connections in the boiler structure
ایری Demand or replacement of boiler control and valves
انی Disability and repair of firefighters and boiler doors
Boiler Mechanical and Electrical Equipment Service Used in the structure of boiler
boiler how do you need repairs?
High sediment on boiler pipes or boilers
bustling grids and furnaces by drying boiler
cracking and leakage of water from boiler pipes
Crack in the networks And the location of the pipes
Failure to operate control equipment such as reliability valves, Leval Controls, etc. Abnormals such as vibration or impact
Increased smoke and contamination: Increase smoke and contamination during combustion
Increase pressure or boiler water temperature: Abnormal increase in pressure or boiler water temperature
What Factors affect the cost of repairing boiler?
Type of Boiler: Capacity, Fuel Type and System System
Decreation: Intensity Damage Parts
Spare Parts Costs: Price of Consumable Parts
Workforce Cost: Wage Repair Specialists
Repair Location: Shipping and Residence Costs if needed
boiler welding
welding containers under pressure, especially boiler boiler, requires sufficient skills and experience. The containers must have a valid certificate. However, before the welding begins, the welding test is taken from the welding test to ensure the skill of the person. After ensuring the welding skill and the network preparation for welding and preheating the E7018 electrode to the extent said in current standards, Welding operations are initiated and staircase by our expert inspection.
Types of Boiler Disadvantage
Control Equipment Development
The water level and steam pressure item is controlled in the boilers. The lack of proper control of the control equipment will damage the boiler. For this reason, the use of standard control equipment is very important during boiler repairs. And note the weekly. If you need to repair the boiler here, the equipment must be replaced or repaired with standard equipment. Testing the performance of control equipment after repair or replacement is essential.
Disruption of Refrigeration
In parts of the pot to insulate or prevent heat increase, the material that burns it. Refrigeration is performed by refractory cement or refractory blankets. Over time and continuous heat in refractory parts, damaged insulators and boiler repair should be done here. For example: Around the burner, there is access valve (access tube), inside the front doors of the boiler, pass window 2 and 2 in dry back boilers and ... refractory.
ordinary cement in these parts is useless and quickly eliminates it. Refractory cement or refractory blankets should be used for repair. This breakdown is recognizable by turning off the pot and opening the boiler door. Usually shutting down and opening the doors of the combustion chamber is done at a periodic inspection that should be done annually. If it is observed at refractory surfaces made with crack cement, it does not repair the pot.
Insulation Development Outside
To prevent energy loss as well as removing hot surfaces of boiler, outer surface by rock wool insulation (Usually 2mm thick) or glass wool is covered and placed on it. Usually, leakage in exterior connections such as fountain, level control, steam output, confidence valve output, etc., damaged insulation And it disappears.
Before repair, leakage insulation must be completely removed and then the insulation is opened and the full face is fully repaired.
