Question: ABSA 3B1 UPDATED ACTUAL Questions and CORRECT Answers Where is the flue gas
when it is 600C? How is the bed density in a fluidized bed boiler controlled? What liquor is added to
the digester?
Answer:
Superheater White liquor
Question: What type of ash conditioning is used in a biomass plant? a) wet scrubber, and electrostatic
precipitator b) wet scrubber and bag-house c) dry scrubber and mechanical precipitator d) dry scrubber
and bag-house what type of baffles is used that has no sharp edges what tubes are surrounded by
refractory and have studs along the length disadvantages of separately fired superheaters Plate air
heater alternate passages in opposite directions air heater corrosion temp must be kept above the dew
point How will flat gauge glasses be affected by alkalinity? what non-return valves has a disc attached
to a piston inside a cylinder? construction of a blow off tank not less 103kpa or 30% where the water
drains out after being separated by the dry pipe separator if the pressure rises above the set pressure in a
high gas pressure switch, what will the contacts do? What shape is a multi spud burner? Why is oil
heated? To facilitate pumping Why is 170 kPa the maximum oil heating steam pressure? what is the
most efficient blade Air foil what affects do the outlet dampers have? How much of primary and
secondary air? What passes through the baghouse filter? What is three element feed control? Fuel
flow-air flow control: What changes after what?
Answer:
Curved baffles Fully studded membrane walls - Higher initial cost - Lower operating efficiency - More
space required The alkalinity will thin the glass above the water line, and its effect increases drastically
as the pH rises. Angle non-return valve through small holes at the bottom Open Circular higher
pressures result in higher pipe surface temp more power at partial loads and less efficient molecules of
air Steam flow, water flow, level. air changes after fuel
Question: What does a direct contact attemperator do to the water spray? What needs to happen for
caustic embrittlement to occur?
Answer:
Vaporizes it after using latent heat from the steam stress, leak, and caustic
