Compare solid, liquid and gaseous fuels by calorific value, storage, handling and firing equipment, naming chain-grate stoker, pulverized coal, pressure-jet burner and gas train components
Describe how to set up and adjust a burner flame for stable ignition and complete combustion, and recognize signs of incomplete combustion
Calculate boiler efficiency by the direct method from fuel rate, steam output and calorific value
List the main heat losses in a boiler and propose at least six practical energy-conservation measures an attendant can apply
Your checkpoint
A worked efficiency calculation using supplied sample figures plus a numbered list of at least six conservation actions with the expected effect of each
Boiler Feed Water Treatment and Feed Systems (water chemistry, scale, corrosion, feed pumps and injectors) & Steam Generation, Steam Systems and Steam Traps
Explain hardness, alkalinity, dissolved oxygen, dissolved solids and pH, and state the damage each causes if uncontrolled
Describe scale and sludge formation, caustic embrittlement, carry-over and oxygen pitting, and match each to its treatment method
Outline internal treatment by phosphate, sulphite and oxygen scavengers and external softening, and state blowdown practice for dissolved solids control
Trace the feed system from hotwell through feed pump or injector to the boiler, and explain the operating principle of an injector and a reciprocating feed pump
Describe the steam system from boiler to trap, and explain how a steam trap discharges condensate while retaining steam
Your checkpoint
A water-treatment and feed-system flow diagram with a troubleshooting table linking at least eight symptoms to their cause and corrective action
Boiler Construction, Types and Classification (fire-tube, water-tube, shell and water-wall designs, mountings and accessories) & Boiler Operation, Starting-up and Shutting-down Procedures & Boiler Inspection, Testing and Maintenance (hydrostatic test, steam test, internal/external inspection, repairs)
Explain the effect of scale, soot and water level on tube and plate temperatures and on the risk of overheating and collapse
Describe routine maintenance tasks such as gauge glass cleaning, water-level control checks, safety valve easing and burner servicing, with the interval for each
Explain how to isolate, drain, open up and safely enter a boiler for internal cleaning, including confined-space precautions
Describe the correct procedure for testing a low-water cut-out and a safety valve under steam
Explain how to prepare a boiler for a prolonged lay-up, either wet or dry, and what corrosion protection is needed
