    Apr 09, 2020 · Loeffler Boiler is a high pressure, forced circulation, internally fired, water tube boiler. There are some points to remember: Generating capacity of the boiler is 95000kg/hr or 95 tonnes/hr. Operating pressure is 140 bar. 2/3 of the total steam generated by the superheater is made to flow into the evaporator drum.Learn More

  • Important Questions and Answers: Water Technology

    (iii). Boiler Explosion: When thick scales crack due to uneven expansion, the water comes suddenly in contact with over-heated iron plates. This causes in formation of a large amount of steam suddenly. So sudden high-pressure is developed, which may even cause explosion of the boiler. 6. Explain prevention of scales formation.Learn More

  • Unit I Water Technology.

    It is a type of boiler corrosion, caused by using highly alkaline water in the boiler. In boiler water, it contains a small amount of sodium Carbonate. In high pressure, it decomposes to give sodium hydroxide. Na CO +H O--- 2NaOH+CO 2 3 2 2 o Then this NaOH reacts with boiler material and it forms sodium Ferrate and this leads to brittlementLearn More

  • Water Handbook - Preboiler & Industrial Boiler Corrosion

    Maintenance of proper pH throughout the boiler feedwater, boiler, and condensate systems is essential for corrosion control. Most low-pressure boiler system operators monitor boiler water alkalinity because it correlates very closely with pH, while most feedwater, condensate, and high-pressure boiler water requires direct monitoring of pH.Learn More

    -Operating the boiler with too high a water level.-Operating the boiler below its design pressure; this increases the volume and the velocity of the steam released from the water surface.-Excessive steam demand. 2. Foaming - This is the formation of foam in the …Learn More

  • The Benefits of Supercritical Boilers

    Apr 19, 2016 · Rather than boiling water to produce steam and then using that steam to turn a plant's turbine, a supercritical boiler operates at such high pressure (3,208 psi/221.2 bar or above) that the Learn More

  • What is a Water Tube Boiler – Explain its Construction

    Aug 28, 2019 · Water Tube Boiler is a high-pressure boiler that operates at a pressure of about 165 bar. Basically, in this boiler, water will be flown inside the tubes surrounded by flue gases. More steam is generated by using this boiler so, the overall efficiency of the boiler is high. The water Tube boiler is shown in the figure below.Learn More

    Nov 30, 2018 · High-Pressure Boilers: High-pressure boilers are used in the thermal power plant to work with more efficiency this boiler contains with water tubes in it. According to the High-pressure boilers function, there is a difference in size. In this High-pressure boilers, the operating pressure is about 160 bars and the steam capacity is around 650 tonnes/hr.Learn More

  • What are the advantages of boiler pressure impregnation

    Aug 27, 2020 · Then we fill the boiler with an impregnating agent. Once this is done, we further increase the pressure in the boiler, so that the wood can absorb the agent properly. All this is a computer-controlled process and ensures that the wood has a longer lifespan. What exactly are the advantages?Learn More

  • High Pressure Boiler: What is it? Types & Characteristics

    Dec 09, 2015 · It eliminates the need of a boiler drum. Advantages of High pressure Boilers. 1.High-pressure boilers use the forced circulation of water which ensures the positive circulation of water and increased evaporative capacity. 2.They require less heat of vaporization. 3.They are compact and thus require less floor space.Learn More

  • Boiler Feedwater - an overview | ScienceDirect Topics

    Boiler feed water quality is limited owing to problems of (1) scaling, (2) corrosion, and (3) foaming. In order to avoid these problems, the quality guidelines shown in Table IV have been adopted. Data in Table IV show a major difference between cooling water and boiler feed water quality constraints, in that boiler feed water has a strong relationship between water quality and the pressure of Learn More

  • Water Tube Boilers | Spirax Sarco

    However, when the pressure in the water-tube boiler is increased, the difference between the densities of the water and saturated steam falls, consequently less circulation occurs. To keep the same level of steam output at higher design pressures, the distance between the lower drum and the steam drum must be increased, or some means of forced Learn More
