boiler test
.......Can cause water hammer - ANS-carryover
a boiler operator log must be maintained in a boiler room containing over: - ANS-a hundred
horsepower
a furnace explosion can be prevented through - ANS-purging after ignition failure
a log e-book is wanted in all plants that have over how a great deal horse power - ANS-100
horsepower
a manometer is calibrated in what units of measurement - ANS-inches of water
a protection tool that video display units the water stage within the boiler and is electronically
connected to a gas solenoid valve is known as a - ANS-low water reduce-off
a protection valve on a low stress hot water boiler will have a max placing of - ANS-one hundred
sixty psig
a steam strain gauge is designed to expose steam calibrated in - ANS-kilos in line with square
inch
a steam strain gauge is designed to expose steam calibrated in - ANS-kilos consistent with
rectangular inch
a thermodynamic steam lure is a steam entice that has movable discs that raises to allow
discharge of air and cools the condensate - ANS-genuine
a thermostatic steam lure is a steam lure that has bellows full of the fluid that boils at steam
temp - ANS-actual
accumulations of soot on heating surface can result in a decrease in - ANS-boiler potential
air is blended with the gasoline outdoor the burner - ANS-true
as solids add alkalinity in boiler water increase - ANS-waterside scaling is multiplied
assuming the valves are of comparable length which one will take the longest to open and close
- ANS-gate
at deuce is used to acquire enough static head for the returning condensate in two pipe gravity
return system - ANS-a return entice
, atmospheric stress is same to - ANS-14.7 psi
boilers are equipped with combination of gas/gas burners for - ANS-extra bendy operation
boiling water having a high water alkalinity may want to develope - ANS-caustic embrittlement
bottom blowdown is satisfactory finished when the boiler is - ANS-underneath light load
carryover can result in - ANS-water hammer
solid iron phase sectional boilers are constructed for what form of draft firing - ANS-mechanical
force and precipitated
mixtures pressured and induced draft is also known as.........Draft - ANS-balanced
cracking of the boiler may be due to: - ANS-caustic embrittlement
draft in a oiler is measured in - ANS-inches of water
draft is a difference in pressure that triggered - ANS-air or gases to go with the flow
how are forged iron sectional boilers prepare - ANS-with push nipples and bolts
how is herbal draft produced - ANS-by the distinction in temp of the fuel within the chimney to
that of air out of doors
how is the air to fuel ratio maintained inside a boiler? - ANS-all the above: modulating motor and
linkage, air damper, butterfly valve
how is the relieving capability of a protection valve measured - ANS-lbs/hr that it is discharging
what number of kilos of steam per hour at 212 F same one horsepower - ANS-34.Five
how tons does a one inch square column of water weigh if it's miles one foot tall - ANS-.Forty
three
how regularly could you blow down a boiler without a chemical water evaluation - ANS-as soon
as each 24 hours
how should an operator perform the handwheel to confirm the position. Of a completely open
guide valve - ANS-circulate it in the closed direction initially after which open the valve lower
back to the unique function
