WTG 634

MAIN CHARACTERISTICS of
Indirect heat exchanger WTG 634

WTG 634 heaters are horizontal indirect fired water bath heaters. WTG 634 gas heaters are designed to preheat the natural gas prior to the pressure reduction process in order to prevent cryohydrates formation because of the  Joule-Thomson effect. The working principle: the heat is transfered from the firebox to the coil tube brundle through wich gas flows, by means of the wather bath.
Reference standard: EN 13445 , API 12 K
CE certificate according to PED 97/23/EC

FUNCTIONAL CHARACTERISTICS WTG 634 heaters can be:
- automatic
- non-automatic
Fuel burning process can be performed by means of:
- natural gas burner
- Diesel-oil burner
- mixed burner
Burners can be:- atmospheric burner
- forced draft burner
Firebox - coil heat transfer medium: water-glycol mixture
OPTIONAL ACCESSORIES Silencer on the exhaust chimney
Spark arrester/flame arrester
Safety thermostat - protects the installation against water temperature increase over the maximum value
Temperature sensor - records the temperature instantaneous value in the water jacket
Temperature sensors - records the inlet/outlet gas temperature
Thermometer - to indicate the water jacket temperature
Level indicator - indicates the water level in the water bath and signals the level minimum limit
Pressure sensors - records the inlet/outlet gas pressure
Pressure gauges - indicate inlet/outlet gas pressure within the pressure equipment
Thermometers - indicate inlet/outlet gas temperature
Safety shut-off valve - ensures overpressure protection
By-pass valve - fitted in the inlet/outlet compartment of the tube bundle for an optimal control of the temperature
Weatherproof cabinet - protects the burner, control equipment and control panel
Skid/Upper frame skid
Thermal insulation
OPERATING CONDITIONS Ambient temperature: -30 ÷ 80°C
Heat transfer fluid temperature: max. 90°C
WORKING MEDIUM Natural gas or other non-corrosive gases

Indirect fired water bath heaters have different constructive designs depending on the pressure equipment type (tube bundle or coil).

  • tube bundle intended for WTG 634 F heater
  • coil provided with adjustable choke bean intended for WTG 634 C heate
  • multiple coils provided with collector and distributor intended for WTG 634 MC heater
