Boiler Water Treatment | Sensors for Process Control

The ETC1021 Gas Pressure Sensor is installed between the two gas isolating valves on the gas train. Once installed the sensor can be used as part of the gas valve proving system and can provide high and low level alarm and interlock functions. Because the sensor is self-checking, the need for mechanical pressure switches is eliminated.

Steam Boiler Pressure - InspectAPedia

Steam Piping and System Sensor Location In residential steam heating systems, steam rises to the radiators and upper floors using the steam pressure generated by the boiler. Normally, the pressure is low, but sufficient enough to push the steam to the upper floors.

QUIZ: Boiler Water Treatment Chemical Guidelines — Part II

If gas is available at $0.50 per therm and #2 oil is available at $1.00 per gallon, which will be the more economical fuel source on the basis of cost per Btu (assume equal efficiencies)? •A therm of gas contains 100,000 Btu for $0.50, or 200,000 Btu per dollar. • A gallon of oil contains 140,000 Btu for $1.00. • Gas will be more economical.

Reducing Steam Pressure. A common way of lowering pressure is by throttling down the size of the steam passageway. For the most basic pressure reduction, it is possible to simply use a conventional globe valve in a fixed partly-open position, or by inserting an orifice plate into the flow of steam. However, any fluctuation in flow rate would be
