Abstract

Boiler combustion efficiency is one of the important factors affecting the performance and operational reliability of steam power plants. One of the parameters that significantly influences combustion efficiency is excess air, which refers to the amount of air supplied exceeding the theoretical combustion requirement. This study aims to analyze the effect of excess air on boiler combustion efficiency at PT PLN Nusantara Power Paiton Unit 9. The research method used is a descriptive quantitative approach through field observations and operational data analysis obtained from the Distributed Control System (DCS). The analyzed parameters include oxygen content (O₂), excess air, boiler load, flue gas temperature, air flow, fuel flow, heat loss, and combustion efficiency. The results show that increasing excess air causes higher heat loss due to the increasing amount of heat carried away by flue gas, resulting in decreased boiler combustion efficiency. At low boiler loads, excess air tends to increase because the combustion process becomes less stable and requires additional air to maintain flame stability. Meanwhile, optimal excess air conditions provide more stable combustion, lower heat loss, and higher combustion efficiency. Therefore, controlling excess air properly is essential to maintain optimal boiler performance, improve operational efficiency, and reduce energy losses in the power generation system.

Abstract

The induction motor in the Low Pressure Boiler Feed Pump (LP BFP) system plays a crucial role in ensuring the smooth operation of the power generation process at the combined cycle power plant. An increase in motor temperature is a key indicator for evaluating performance and detecting potential operational issues at an early stage. This study aims to analyze and evaluate the performance of the LP BFP induction motor based on temperature rise and motor vibration conditions at PT PLN Nusantara Power UP Gresik. The research method employs a descriptive quantitative approach through field observations, temperature measurements, vibration analysis, and the collection of motor operational data. The results show that the motor temperature on the Drive End (DE) side is 56.8°C and on the Non-Drive End (NDE) side is 47.6°C, which are still within normal operating limits. However, the vibration analysis results indicate bearing damage with an ALARM status based on ISO 10816-3. Therefore, regular temperature monitoring and preventive maintenance are crucial to maintaining the motor’s operational reliability.

Abstract

The utilization of biomass in the form of sawdust as a co-firing fuel in boilers has increasingly been implemented to reduce coal consumption and carbon emissions. Sawdust has a high volatile matter content and is readily available; however, its ash characteristics, which contain alkali elements such as potassium (K) and sodium (Na), as well as its relatively low ash melting point, have the potential to increase fouling formation on boiler heat transfer surfaces. Fouling refers to the accumulation of deposits on the economizer, superheater, reheater, and air preheater, which can reduce heat transfer efficiency, increase flue gas temperature and differential pressure (DP), increase induced draft fan load, decrease main steam temperature, and increase sootblower operating frequency. This study aims to analyze the effect of sawdust combustion on fouling formation using boiler operational data obtained from the Distributed Control System (DCS). The parameters analyzed include coal flow rate, sawdust flow rate, total fuel flow, co-firing percentage, primary air flow, secondary air flow, flue gas O₂ content, furnace exit gas temperature (FEGT), flue gas temperature to the stack, economizer differential pressure, air preheater differential pressure, main steam temperature, and sootblower operating frequency. Data were collected at fuel mixture variations of approximately ±3% sawdust relative to the total fuel flow, with hourly intervals for a minimum of 24 hours for each operating condition. The analysis was conducted by comparing changes in temperature, differential pressure, and boiler performance at each variation of sawdust percentage. Indications of increased fouling were identified by rising flue gas temperatures and differential pressure, reduced heat transfer effectiveness, and increased sootblower operation requirements. The results of this study are expected to show that increasing the percentage of sawdust tends to increase fouling formation; however, there is still an optimum limit for sawdust utilization that can be applied without significantly reducing boiler efficiency and reliability.
