Reciprocating Steam Engine (ES) study plan

Define saturated, superheated, and wet steam states and compute dryness fraction from given pressure and enthalpy data without reference notes

Sketch and label a pressure-enthalpy path for a simple reciprocating engine cycle, identifying admission, expansion, release, and compression events

Explain how clearances, cutoff, and compression ratio shift indicated work and steam rate in a reciprocating cylinder

Identify the major stationary and moving components of a horizontal mill-type engine from a written description alone

Differentiate simple, compound, and uniflow arrangements by their expansion sequence and porting logic

Describe piston, rod, crosshead, guide, and connecting-rod load paths and the alignment relationships that keep them concentric

Compare D-slide, piston, and poppet valve constructions by sealing, wear, and steam-tightness characteristics

Trace the motion of a simple eccentric and explain how angular advance produces lead and cutoff

Explain why Stephenson link reversing gear shifts cutoff and how the die blocks and lifting links interact

Distinguish shaft governing from throttle governing in terms of steam economy and speed droop

Compute valve travel, lap, and lead relationships for a given eccentric setting and predict the resulting cutoff

Explain how a centrifugal governor with a sleeve and pilot valve positions the throttle or trip mechanism

Sequence a cold-start procedure including drain and warm-through steps, and justify each step by the risk it removes

Describe a controlled shutdown that avoids thermal shock and leaves the machine in a safe, drained condition

Identify the hazards of water hammer and hydraulic lock and state the corrective action for each

Explain how a boiler, superheater, and steam header deliver dry steam to the engine and where water carryover originates

Identify trap, separator, and non-return valve functions in the steam supply and condensate return path

Select lubricant type and feed rate for cylinder, valve chest, and main bearings and justify each choice

Describe hydrostatic and splash lubrication of bearings and the consequences of over- and under-feed

State cooling-water and jacket-temperature limits and the effects of scale and air binding on heat transfer

Perform a routine inspection round that checks packing glands, gland followers, and bearing temperatures and records findings

Diagnose knocking, uneven running, and loss of power from described symptoms and rank probable causes

Explain how to detect and correct valve timing drift and worn eccentric straps

Describe repacking a stuffing box and setting gland follow-up without over-tightening

Distinguish steam-side faults from mechanical faults using pressure, temperature, and sound evidence

Plan a cylinder and valve-chest inspection including measurement of bore wear, ring gap, and valve lap

State acceptance criteria for piston-rod runout, guide clearance, and bearing fit and decide repair versus replace

Apply lockout, isolation, and drain-down steps before opening any steam-containing component

Identify pressure-relief, gauge, and inspection-code obligations that apply to the steam system

Describe condensate, blowdown, and waste-oil handling practices that meet environmental requirements

Recompute indicated horsepower and steam rate from indicator-card data and compare against expected values

Re-derive valve events from a measured indicator card and identify late or early cutoff

Solve mixed troubleshooting scenarios that combine thermodynamic symptoms with mechanical wear

Explain how superheat loss or wet steam shows up in card shape and exhaust behavior

Build a personal list of the formulas and ratios most often missed on practice questions

Rehearse the full startup, normal running, and shutdown sequence from memory and correct any gaps

Answer safety and code questions on isolation, relief devices, and confined-space entry without notes

Review all logged errors from prior weeks and restate the corrected reasoning for each

Complete a timed mixed-domain practice set and analyze the weakest two domains

Write a final one-page summary of key numbers, limits, and procedures to review before the exam
