A.     Boiler Efficiency
To get the most out of the boiler system it is necessary to implement a complete maintenance/efficiency plan to maintain every aspect of efficiency. Basically,  boiler  efficiency  represents  the  difference  between  energy  input  and  energy  output.   Boiler efficiency describes the fraction of fuel energy that is converted into useful steam energy. In this work, efficiency comes down to properly evaluating the performance of the boiler and the performance of the burner. There  are  three  terms  that  influence  boiler  efficiency; Combustion  Efficiency and Fuel-to-Steam Efficiency and Thermal Efficiency.
Combustion efficiency is an indication of the burner’s ability to burn fuel and the ability of the boiler to absorb the heat generated. The amount of unburned fuel and excess air in the  exhaust  gas  are  used  to  assess  a  burner’s  combustion  efficiency.  Burners  performing  with extremely  low  levels  of  unburned  fuel  while  operating  at  low excess  air  levels  are  considered efficient. In other words, combustion efficiency is measured by dividing the usable heat produced by the fuel input in MJ/h content. This calculation is based on the actual heat available produced by the system after heat loss up the stack and other heat losses which do not provide usable heat. To determine Boiler Efficiency, there are two methods that are typically utilized but generally prefer Direct Method (Input-Output Method) to calculate. It needs only the useful output (steam) and the heat input (i.e. fuel) for evaluating the efficiency. This efficiency can be evaluated using the formula:

B.    Procedure of Finding Boiler Efficiency
1)    Measure steam stream by means of kg over a set period, for example 60 minutes. Use steam integrator readings, if accessible, and right for alignment pressure. On the other hand, utilize the feed water integrator, if accessible, which will as a rule not require an amendment for pressure.
2)    Measure the progression of fuel over a similar period. Utilize the gas or oil integrator, or decide the mass of strong fuel utilized.
3)    Convert steam stream, feed water stream and fuel stream to indistinguishable vitality units, for example Btu/lb. or on the other hand kJ/kg.
4)    Calculate the productivity utilizing the accompanying condition: Efficiency = 100 x (steam vitality – feed water vitality) ÷ fuel vitality.

C.    Energy Efficiency by Frequency Reduction
In Fig 4, a Voltage Frequency Drive is introduced for examination of execution of Boiler System regarding Energy Efficiency. Without Drive, it is legitimately controlled and fixed at a solitary recurrence yet after establishment of Drive, vitality productivity is improved and furthermore lessens cost.

D.     Analysis to Improve Boiler Efficiency & Plant Efficiency using MATLAB
The organization is utilizing a fundamental rankine cycle with an open framework. The wellspring of crude water for evaporator is siphoned from the close by Bore well to the save plant bore well for further inside and outside medications. Superheated steam created from heater is utilized to run steam turbine for heat age and for heat process in the plant. The fumes steam from turbine is then consolidated and later released and blended in with squander water from the plant activity to the gushing treatment. The fundamental goal of this investigation is to improve by and large heater productivity and plant proficiency. At first Steam Pressure 360 PSI and temperature 280°C separately for evaporator Operation. It is estimated soon after the evaporator at third Point in the figure. Presently, it expands the kettle strain to 5.0 MPa while superheated steam temperature is kept up at 280°C. It gives the improvement in Boiler Efficiency by modest quantity. Presently, in second case, it expands the temperature from 280°C to 400°C and weight will stay same. Just temperature will increment. At that point it additionally influences the improvement in Efficiency of System.
