11.20 Cause – Insufficient Reconcentration of Glycol. 1. Verify the reboiler temperature with a test thermometer and be sure the temperature is in the recommended range of 350°F to 400°F for triethylene glycol. The temperature can be raised closer to 400°F, if needed, to remove more water from the glycol. 2.

The maximum temperature that we recommend you set your radiator output to is 80 °C. If you have a conventional boiler system, your water cylinder will have its own thermostat. This is usually fitted on the side of the tank. You should set the temperature between 60 and 65 °C but for maximum efficiency, it should be set to around 60 °C.

A high-pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal. In the later years of steam, boiler pressures were typically 200 to 250 psi (1.38 to 1.72 MPa). High-pressure locomotives can be considered to start at 350 psi (2.41 MPa), when special construction
