OBJECTIVES

 

To determine the performance of the steam engine such as torque, engine power output, specific steam consumption and cycle efficiency.

 

 

4. THEORY

 

Criteria for performance can be calculated used below equations.

 

Engine torque, T = (F₁-F₂)R [Nm]

 

Engine break power, Bp = [kW]

Specific steam consumption, ssc =  [kg/kW.h]

 

 

where:

 

N = Engine speed                                             [rev/min]

F1 = The changes in the first load spring            [N]

F2 = The changes in the second load spring       [N]

R  = Radius of the pulley, 0.056                        [m]

M_f = steam consumption rate                            [kg/h]
