Model HRW

SKU: HRW

Refractory Protective Well

The Delta Controls Model HRW Well is designed to protect the thermocouple element well from physical damage along with protecting the reactor nozzle and shell from the hot gas convection inside the reactor. The HRW is placed in a hole through the refractory lining in the base of the thermocouple nozzle on the Claus thermal reactor.

The HRW also prevents thermal shock damage to the element well by partially insulating it from sudden severe changes in gas temperature, such as during steam quenching. Several material formulations are offered. Each one enhances various physical characteristics: the various blends are formulated for characteristics of mechanical strength, resistance to thermal shock, and the ability to withstand extremely high temperatures.

Features

  • Protects thermocouple element well from thermal shock, flame impingement and steam quench
  • Formulated material blends provide enhanced resistance to corrosion, temperature, and thermal shock
