In the power/heat industry, instrumentation is required for several critical processes to ensure safe, efficient and accurate operation.

1. Power generation process

(1) Boiler and steam system

Temperature sensor: used to monitor boiler water temperature, steam temperature, etc., to ensure that the temperature is within the safe range.

Pressure transmitter: Monitor the pressure of boiler and steam pipe to prevent overpressure operation.

Liquid level gauge: Monitor boiler water level to prevent dry burning or full water accidents.

Flowmeter: Monitor steam flow and provide basis for power generation efficiency calculation.

(2) Fuel system

Flow meter: Monitors the flow of fuel (such as coal, oil, gas) to ensure combustion efficiency.

Analytical instruments: Monitor fuel composition and optimize combustion processes.

(3) Cooling system

Temperature sensor: Monitor the cooling water temperature to ensure that the equipment does not overheat.

Flowmeter: Monitor cooling water flow to maintain cooling effect.

2. Heat transmission

(1) Heat pipe network

Temperature sensor: Monitor the temperature of hot water in the pipe network to ensure the quality of heating.

Flow meter: Monitor hot water flow and balance heating load.

Pressure transmitter: Monitor the pipe network pressure to prevent leakage and pipe explosion.

The power/heat industry requires a variety of instruments in multiple processes such as power generation and heat transmission to ensure the safe, efficient and accurate operation of equipment. These instruments play a vital role in ensuring energy supply, improving energy efficiency and protecting the environment.
