MA oil burners test Questions With Complete Solutions
. Upflow-type Central Furnace. Correct Answers .. A furnace
designed with air flow essentially in a vertical path, discharging
air at or near the top of the furnace.
(a) Gravity-type Central Furnace. Correct Answers A central
furnace depending primarily on circulation of air by gravity.
(a) Metering (Regulating) Valve Correct Answers . An oil
control valve for regulating burner input
(b) Gravity-type Central Furnace with Integral Fan. Correct
Answers . A central furnace equipped with a fan as an integral
part of its construction and operable on gravity systems only.
The fan is used only to overcome the internal resistance to air
flow.
(b) Medium-Heat Industrial Appliance Correct Answers (b) An
industrial appliance such as an annealing furnace (glass or
metal), charcoal furnace, galvanizing furnace, gas producer,
commercial or industrial incinerator, and steam boiler operating
at over 50 psig (345 kPa) pressure when such appliance is larger
than 100 cubic feet (2.8 m 3 ) in size, and other furnaces
classified as medium-heat appliances in accordance with
recognized good practice
(b) Safety Valve. Correct Answers An automatic oil control
valve of the "on" and "off" type (without any by-pass to the
burner) that is actuated by a safety control or by an emergency
device.
,(c) Gravity-type Central Furnace with Booster Fan. Correct
Answers . A central furnace equipped with a booster fan that
does not materially restrict free circulation of air by gravity flow
when such a fan is not in operation.
(d) Forced-Air-type Central Furnace.. Correct Answers . A
central furnace equipped with a fan that provides the primary
means for circulation of air.
1. Horizontal-type Central Furnace. Correct Answers A furnace
designed with air flow through the
furnace essentially in a horizontal path.
Air Heater. Correct Answers . An indirect-fired appliance
intended to supply heated air for space heating and other
purposes, but not intended for permanent installation.
Air pressure switch . Correct Answers An electrical switch
designed to prove that the proper draft has been established by
the power venter or burner and allows the burner to operate. If
the power venter or burner is not performing so as to satisfy the
operating requirements of the equipment for safe performance,
the switch will de-energize the burner control circuit preventing
the burner from operating.
Anti-flooding Device Correct Answers . A primary safety
control that causes the flow of fuel to be shut off upon a rise in
fuel level or upon receiving excess fuel, and which operates
before the hazardous discharge of fuel can occur
, Appliances; industrial Correct Answers (a) Low-Heat Industrial
Appliance. An industrial appliance such as a commercial
cooking range, pressing machine boiler at any pressure, bake
oven, candy furnace, stereotype furnace, drying and curing
appliance, and other process appliances in which materials are
heated or melted at temperatures (excluding flue-gas
temperatures) not exceeding 600°F (316°C).
Appliances otherwise classed as medium-heat appliances may
be considered as low-heat appliances if not larger than 100 cubic
feet (2.8 m 3 ) in size excluding any burner equipment and
blower compartment
Application Permit/Certificate of Completion. Correct Answers
A standard form issued for use in all jurisdictions
throughout the Commonwealth
Approved Correct Answers . Unless otherwise indicated, listed
or approved by a nationally recognized testing
laboratory
Authority Having Jurisdiction. Correct Answers . The state fire
marshal or his designee
Boiler, High Pressure). Correct Answers . A boiler for
generating steam at pressures in excess of 15 psi (103 kPa), or
for heating water to a temperature in excess of 250°F (121°C) or
at a pressure in excess of 160 psi (1103 kPa).
