  • Pressurised Deaerators | Spirax Sarco

    A cost saving can be achieved with respect to chemicals - this argument becomes increasingly valid on large water-tube type boilers where flowrates are high, and low TDS levels (< 1 000 ppm) need to be maintained in the boiler feedwater. Chemicals added to control the oxygen content of the boiler water will themselves require blowing down.Learn More

  • Boilers : Types and Classification

    Water tube boilers: In water tube boilers, water and steam flow inside the tubes and the hot gases flow over the outside surface. Modern high capacity boilers are of water tube type. The boiler circulation system is constructed of tubes, headers, and drums joined in arrangement that provide water …Learn More

  • Finding the Root Cause of Boiler Tube Failures

    Symptoms: Aggressive localized boiler tube corrosion and loss of tube wall.Pits can act as stress-concentration sites which can be initiation points for stress-related corrosion mechanisms. Causes: Oxygen pitting occurs with the presence of excessive oxygen in boiler water.It can occur during operation as a result of in-leakage of air at pumps, or failure in operation of preboiler water Learn More

  • Consulting - Specifying Engineer | Boilers: Types

    Mar 22, 2013 · Mar 22, 2013 · Flexible water tube boilers typically consist of an upper and lower water drum with a series of bent steel tubes designed to absorb the stresses of thermal expansion (see Figure 2).

  • Why are steam car boiler round

    Re: Why are steam car boiler round. March 06, 2003 02:46PM. Some water tube boilers like the White or Doble could be round to simplify the gas flow through them or make it easier to form the coils. There were box shaped boilers in some old setamers. The Doble Detroit and the Bryan are two examples.Learn More

  • Boiler 101 | What is a boiler? - Home | American Boiler

    In watertube boilers, boiler water passes through the tubes while the exhaust gases remain in the shell side, passing over the tube surfaces. Because tubes can typically withstand higher internal pressure than the large chamber shell in a firetube, watertube boilers are used where high steam pressures (3,000 psi, sometimes higher) are required.Learn More
