Viscosity Trim Controller

Application | Features

The Viscosity Trim Controller improves burner performance by supplying the burner with the proper amount of fuel required for the optimal performance. The controller does this by monitoring the mass flow rate of the fuel and adjusts the heater automatically to control the viscosity of the fuel based on the fuel-air requirements of the burner. Maintaining consistent fuel viscosity is critical when operating with varying viscosity fuel such as No. 6 Fuel Oil or residual fuels.

  • Application
  •  

Based on the 1980s Preferred Viscometer, which adjusted the viscosity of fluid via mechanical methods, the Viscosity Controller uses electronic sensors to monitor and adjust the flow of fuel to the burner.

Residual fuel can vary in viscosity, depending on which site it is processed at. Heaters installed in fuel lines keep the fuel at a constant heat but do not account for viscosity changes. The Viscosity Controller automatically senses and adjusts heaters to maintain a consistent fuel viscosity needed for the burner to run at peak performance.

  • Monitors and maintains a constant burner fuel-air ratio by adjusting the heater to maintain a constant fuel mass flow rate maintaining peak burner performance.
  • Uses the Preferred PCC-IV controller for power and software, in conjunction with multiple other senors and gauges.
