O2
This controls the amount of excess O2 in a heater
Air Registers
This helps control draft on a heater
Damper
These are the 3 major sections of a vertical, cylindrical heater
Radiant section, convection section, stack
Draft is on target but O2 is below target
Open air regiser
This is produced due to incomplete combustion
Carbon Monoxide
What did the buffalo say to his son when he dropped him off at school?
Bison
Air entering the heater and not taking part of combustion is called this
Tramp air
Flue gas is removed from the heater through this heater part that usually has strakes
The stack
In general, ~2/3 of the heat transfer occurs in this secion
Radiant section
Draft is higher than normal and O2 is lower than normal
Open air register
Natural gas is an odorless, gaseous mixture of hydrocarbons, predominantly made up of this
Methane
What do you call a bear with no teeth?
Gummy bear
The percent of total air supplied that is more than what is required for Stoichiometric combustion
Excess air
While an induced draft heater is not common in refining, these other three styles are
Natural draft, balanced draft, and forced draft
The purpose of this section in a Natural draft heater is to recover heat to increase the heater's overall efficiency
Convection section
Draft and air are both lower than normal
Open damper
SO2 and NOx are extremely reactive and decomposes in contact with water, oxygen, and other chemicals to form this
Acid rain
This is a typical dad response when asked if he got a haircut
I got them all cut or no, I got my ears lowered
Elevated levels of excess air increases fuel consumption and increases this, an essential component of air pollution
NOx
This controls the excess air for a forced draft heater
Forced draft blower, fan louvers or combustion air dampers
The lower 2-3 rows of convection section tubes, known as these, receive a significant amount of radiation heat transfer
Shock or Shield tubes
Draft is higher than normal and O2 is on the high side of normal
Close damper
Operating above or below this will trip the fuel gas on your heater
Pressure
The place that Dads say that people are dying to get in
Cemetery
Operating with insufficient excess air may generate levels of CO and this which is required for a fuel rich firebox
Combustables or unburned fuel
This is considered the most efficient draft style of heater
Balanced draft
This burner type uses recirculation to help reduce NOx
Low NOx burner
Your O2 reading is 1%
Nothing. Air hold. Slowly cut fuel gas 10% of flow per minutes if override hasn't activated. Let operators know to stay away from the heater
The three T's of combustion are Time, Turbulence, and this....is it hot in here?
Temperature
How are the movies Titanic and The Sixth Sense the same?
ICY ( I see) dead people
