Boiler thermometer should be installed in what position?

Boiler is a kind of energy conversion equipment, the energy input to the boiler is the chemical energy of the fuel, power, boiler output has certain heat of steam, hot water or organic heat carrier. Refers to the literal meaning of the pot on the fire to heat the water container, furnace refers to the place of fuel combustion, boiler including boiler and furnace of two parts. Hot water or steam boiler of can directly provide the required heat energy for industrial production and people's life, also can be converted into mechanical energy by steam power device, or by a generator converts mechanical energy to electrical energy. Provide hot water boiler is called hot water boiler, mainly for the life, also have a small amount of application in industrial production. Generate steam boiler called steam boiler, often referred to as 'for boiler, used for power generation, shipbuilding, locomotive and industrial and mining enterprises. Industrial boilers are usually equipped with a safety valve, pressure gauge, water level gauge, thermometer, etc. , to ensure its safe operation. Boiler thermometer should be installed in the following location: 1) Superheater of export, import and export of reheater temperature 2) Made up of some parallel tubes of superheater of export of steam temperature in each group 3) Attemperator before and after the steam temperature of 4) Cast iron of economizer exit water temperature 5) The smoke of coal powder boiler furnace outlet temperature 6) The smoke of reheater and superheater inlet temperature 7) The temperature of air preheater air outlet 8) Smoke exhaust smoke temperature of 9) Fuel boiler burner fuel inlet oil temperature of 10) The rated steam pressure is greater than or equal to 9. 8 mpa boiler drum of the upper and lower wall temperature of 11) The rated steam pressure is greater than 9. 8 mpa of boiler superheater and reheater coil metal wall temperature 12) Fuel boiler air preheater outlet smoke temperature
