Steam boiler problems and methods of treatment

Problems are divided into boilers to:

(A) The problems of water nutrition. (B) Add a solution of chemical problems "solution of caustic soda solution and sodium triphosphate" (c) the problems of fire fuel. (D) The problems of pipes and pressure vessels. (A) The problems of nutrition and water treatment methods: The problem: the presence of water hardness nutrition. Cause: The use of untreated water.

Methods of Treatment:  - Turn on the efficiency of detection softening "resin" as well as the quantity of each exchanger. - activate the resin exchanges rates and a commitment to operating a Bmassanana 18 hours of work for each exchanger and activate the work of two instead of one. - Inspection of roll-laundering transactions for fear that it will be smuggling.  - The highest rate of disposal of the plant is supposed and requires action to reduce the rate of average imposed.

 hardness of water entering the top of the embargo and requires either softening by using the methods of water initially create a water treatment or reduce the rates so as to act to reduce the rate of water per liter of resin is less than 10 Termaah / l according to the number of initial hardness of raw water. - make sure there are no sources of water is water intensive nutrition and water treatment.

 When the boiler water hardness "inside the boiler," you need to add a solution triphosphate

Sodium quickly so get rid of the hardness and the organization within the boiler blow down process instantaneous.

Problem: the existence of the proportion of oxygen dissolved water in the high nutrition causes an oxygen corrosion of metal pipes of the boiler. Reason: Do not remove the oxygen in water nutrition.

Treatment: the need to ensure the use of high efficiency gas separator capable of reaching the concentration of oxygen in the water emerging from it within the prescribed percentage, which depends on the operating conditions of boilers in terms of suction. Problem: the presence of oil (mineral oil) in water and nutrition that cause foam Boilers and works as a buffer to the heat transfer.

Cause: leak with the water vapor feedback from the condenser and the number of machines that use steam and water-intensive ones.

Treatment can be used Diatom (Diatomite), a type of powder and the powder can reduce the amount of oil to 0.1 mg / Trouw for the use of chemicals that collects oil and deposited (Chemical Coagulants) and is usually used with aluminum sulphate

Alkali such as caustic soda. (B) Add a solution of chemical problems. Problem: the high figure, which shows the alkali metal of the boiler shell and the formation of foam and the kidnapping of the boiler. Reason: add a chemical solution, particularly sodium oxide Aider and a high percentage more than required. Ela c: part of the blow down and boiler water feeding the boiler with clean water until the alkali is adjusted figure to him.

Problem: The lower figure shows the metal phosphate which boiler tubes of the impact of chemical corrosion. Reason: the large and irregular solutions to add chemical and blow-down sequential and in large quantities and do not add sodium phosphates and only add Aider and sodium oxide.

Problem: The high solids water boiler, putting the boiler to form crust. And the occurrence of furan in the boiler and the formation of foam by adding any quantities of soda. Cause: The use of water is suitable for boiler feed or add caustic soda at high rates and non-regular and non-instantaneous blow-down. Treatment: blow down of the boiler and ensure appropriate use of water to feed the boiler.

Problem: low exponent Aloedrogeny this helps to destroy the protective layer Almjnati of metal pipes of the boiler. Reason: the arrival of water with as low Oedrogeny boiler or not to maintain the alkali number of the vessel. Therapy: raising the exponent of the exponent Aloedrogeny sure Aloedrogeny to feed water and make sure of the number of alkaline water boilers (inside the boiler). .................................................. .......

Loss in the boiler is divided into losses in the boiler to the two main pillars: a) it can not get rid of it includes:  - loss when you start the boiler and adjust the operating level.  - loss through the stages of the operation and exit of steam from the drainage hole of the roasted until a certain pressure

- Heating lines, steam and blow down water condensed on the outside and make sure they are clean. Instantaneous blow-down of the boiler to ensure safe operation of blow down Ilov and disposal of sediment resulting from adding chemicals.  Blow forced to adjust the water level Palm gel.

B) it can get rid of it includes:- leaking water or steam from Ochac (faces) Flinched - Links - Fisheries steam - Ilov safety ............ etc.  - during operation must be completely sure of the level water does not occur until the blow down water unnecessarily.

* Latent heat: when the liquid to a temperature of saturation certified the start boiling temperature is called the amount of heat needed to vaporize a unit mass of liquid boiling latent heat latent heat addition leads to an increase Anthalbea article in the same amount.

* Heat roasting: to raise the temperature of the dry steam saturated above the saturation temperature is heated and can not be roasting steam in the boiler boiler always contain water, and roasting steam flowing steam saturated first cylinder boiler (boiler) to a roasted, which consists of a tube through inside the steam and heat from the outside by the combustion gases.

* Identify the properties of steam and their importance: the images Alboukharhoahaddy water. Water + heat = the amount of vapor that is Alboukharhoumeah carrying amount of heat is called the amount of heat transferred per unit of steam by weight ((Alanthalbea)).

The steam is divided into: a) saturated vapor ((the percentage of water loaded = 1)) b) wet steam ((= amount of water loaded with less than 1)) c) steam roasted ((= amount of water loaded with zero))

To get to know the specifications of the steam is sufficient to identify two properties of properties such as: temperature. * Pressure. * Alanthalbea. * Size qualitative. * The proportion of the drought of water laden ...... etc.

Boot to the vessel before starting the driver must ensure the following elements: -

 - Water: Make sure the water level in the efficiency and the boiler.- Air atomization of fuel: air and devices (if pneumatic). - Fuel pumps and fuel. - Temperature of the fuel oil: 100 degrees Celsius.  - Review of lubrication in the moving parts. - Must review all valves and sluice gates.  - Cooling water.

Run with diesel boiler (boiler 30 kg / cm 2) before the start you must do the following: -- Make sure the water level in the boiler. - Ensure that all valves in the desired position. make sure to run the main air fan- Ensure the safety of the Fon and the cleanliness of the oven and lock the doors of the inspection.  Make sure heating fuel oil to 100 degrees C. Viscosity to be suitable for ignition.

 - Begin to ignite Fon noting all the variables (temperature - pressure  ...). 7 - Must adjust the rate of fire so that the change in water pressure and temperature is slow (so that the pressure up to 30 kg / cm 2 after 4 hours). Note: - With the increased pressure and temperature increases the volume of water in the boiler, as well as the water level.. So are the savings of water and reset charged?

- When you access a pressure of 2-3 kg / cm 2 open wrap ventilation on the boiler top. - When you access a pressure of 10 kg / cm 2 open wrap a small opening for steam heating steam line. - When the pressure reaches to 15 LMO / cm 2 begin to open the main steam roll gradually.  - Steam boiler is mixed (a pregnancy outside) after the stabilization of the boiler and the regularity of his work.
