GS – GAS FIRED STEAM SUPERHEATERS SMALL UNIT ON FORKLIFT ACME GS Series Steam Superheaters are auxiliary equipment to steam boilers. They are built to meet the specific design and performance requirements of each application. Burners are AGA or CGA listed with UL, CSA, FM, IR or other gas train standards as requested or applicable. They are complete with an original OEM burner control panel. Pressure sections are built to ASME code. National Board or CRN registrations are available. The burner control panel is supplemented by the ACME Temperature and Control Panel of NEMA 12, 4 or 4X construction, incorporating the main power switch, digital electronic indicating temperature controller with high limit protection, audible and visual alarm circuits with manual reset, high temperature stack detector and interlock connection confirming steam flow. The coil design is available for operating pressures of up to 800 PSIG and temperatures up to 1200˚F. Steam flow is only limited by practical size considerations. The ACME Horizontal or Vertical Superheaters have inlet and outlet flanged connections oriented to suit local conditions for simplified field installation. A pressure safety valve is standard. The casing of the Superheater could be in Carbon Steel or Stainless Steel as required. It is further insulated with H.T Ceramic Fiber which in turn is protected by an aluminum cover. The ACME Superheater is delivered to site on a skid prewired and prepiped requiring only steam, gas, main power and stack connections. Two Service and Operating Manuals are provided with each unit. Special features such as weatherproof construction and stainless steel insulated casings for corrosive ambient conditions can be provided if required. While ACME Electric Steam Superheaters using SCR power controllers can track demand variations between 0 and 100%, the gas fired Superheater’s performance is limited by the gas burner’s capabilities. On large gas burners it is possible to modulate from 25% to 100% of output. Small size burners are provided with HI-LO-OFF capacity control. When the burner is switched OFF because of low load, the accumulated heat in the coil and casing provides a flywheel effect reducing any temperature variation. Burners for different gas mixtures are available. Also burners for light oil #2 – dies
