Code of Practice for the Safe Operation of Thermal Oil Heaters CHAPTER 2 2. ESSENTIALS OF THERMAL OIL HEATER 2.1 General Thermal oil heater is normally operated below the boiling point of thermal oil. The operating pressure is the pump pressure to circulate the thermal oil through the heater with sufficient flow to prevent overheating of thermal oil.
CHAPTER TWO: Boiler Operation Maintenance & Safety Study Guide 2.1 Boiler Design and Construction Boiler: A boiler is a closed vessel in which water is heated, steam is generated, superheated or any combination thereof under pressure or vacuum by the direct application of heat from combustible fuels or electricity. The steam produced is used for
The great diversity in the characteristics of the heat recovery system, such as gas composition, aggressiveness of these gases, amount and type of ash, the required temperatures of the gas and of the heat transfer fluid, gas flow, heat differential of the heat transfer fluid, gas pressure at the intake of the heat recovery boiler and, therefore, the pressure that it can control, etc., etc

boiler (e.g. the combustion chamber and heat exchanger). As the boiler continues firing for a prolonged period, the inner part of the boiler will reach thermal equilibrium and the boiler will reach its steady-state efficiency, as in the full load test. An example of a boiler in thermal equilibrium with a full load efficiency of 80% (gross) is

To perform the oil burner "smoke" adjustment correctly and to avoid over-firing or overheating the boiler, as well as to avoid an inefficient set-up that sends too much heat up the chimney, the heating service tech will first set the oil burner for just a trace of smoke (#1 in our photo at left), then s/he will slightly increase combustion air until the trace just vanishes to a zero smoke reading (#2 and #3 in our photo)
Typical flue gases from natural gas-fired power plants may contain 8-10% CO 2, 18-20% H 2 O, 2-3% O 2, and 67-72% N 2; typical flue gases from coal-fired boilers may contain 12-14 vol% CO 2, 8-10 vol% H 2 O, 3-5 vol % O 2 and 72-77% N 2.
