Introduction of ASME Horizontal Gas Fired Steam Boiler

ASME horizontal gas fired steam boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.

Features of ASME Horizontal Gas Fired Steam Boiler

  1. Long working life
  2. 3-pass and wet-back are designed to avoid the damage of back tube sheet from the high temperature smoke.

  3. Compact desegn
  4. Threaded firetube and corrugated furnace are used to increase the heating area. That allows over 30% of the energy to be absorbed in the furnace. This means a shorter boiler overall. Definitely, it can save your boiler room construction costs.

  5. Ease of maintenance
  6. Everything is up front,adjustable and accessible.

  7. New type economizer
  8. It is made by finned steel tubes. The material is ND steel (09CrCuSb), which is acid-resistant and corrosion-resistant at low temperature. It is smaller but the heat exchanging area is bigger than normal. By calculation, It can save around 5% fuel.

  9. Low emissions
  10. Lowering emissions in the ZOZEN-WNS series of boiler involves two key factors:

    (1) advanced burner solution;

    (2) the proper sizing of furnace to minimize nitrogen oxides and other contaminants from forming during the combustion process.

  11. High Efficiency
  12. Attaining high fuel to steam/water efficiency in a boiler today requires a highly engineered package from a single source who is providing integrated burner, controls and the heat exchanging vessel. Zozen WNS series of boilers is the premier package in the domestic Industry guaranteeing the highest efficiencies.

  13. Safety control system
  14. We design the safety interlock system with multiple protection and alarm functions

    – Protection program of automatic ignition

    – Locking and protection program of operation

    – Protection program of extinction

    – Protection program of completion

    – Protection program of water pumps (pressure loss)

    – Protection program of ignition failure

    – Protection program of combustion engine malfunction

    – Protection program of combustion engine flameout

    – Sound-light alarm of high pressure

    – Sound-light alarm of high limit water level

    – Sound-light alarm of low limit water level

    – Sound-light alarm of super-high temperature of hot water
