paper, only improvements in power output were considered, not heat rate improvements. Steam Path Audit For the first opportunity identifying and quantifying the internals of one steam turbine were examined during the maintenance overhaul. By developing a computerized model of the design internals and comparing actual conditions with
Boilers and chillers have long been the workhorses of hospital HVAC systems, and operating them safely, efficiently and sustainably is a continual challenge for health facility professionals. Fortunately, equipment manufacturers are addressing these concerns in their latest product rollouts, and new generations of boilers and chillers offer

Abstract: In coal-fired power plants, it is critical to improve the operational efficiency of boilers for sustainability. In this work, we formulate real-time boiler control as an optimization problem that looks for the best distribution of temperature in different zones and oxygen content from the flue to improve the boiler's stability and energy efficiency.
The paper presents experimental and numerical investigation of pulverized coal combustion process analysis and optimization. The research was conducted on the front-fired pulverized coal boiler with dedicated low-NOx furnace installation. In order to find optimal boiler operating conditions the acoustic gas temperature measurement system and mass flow rate of pulverized coal measurement system
There are typically two types of boilers in the industry that utilize a standby-mode strategy -auxiliary boilers and process boilers. Each boiler type has a very specific role but essentially performs the same function of providing steam on demand. To understand boiler standby selection, it becomes
This paper outlines the history and structural and technical characteristics of boiler feed pumps (hereafter referred to as BFP), which are high-pressure pumps mainly used for thermal power generation. In a thermal power plant, the BFP is one of the criti-cal auxiliary machines that are equivalent to the heart of the plant.
Modeling and Efficiency Optimization of Steam Boilers by Employing Neural Networks and Response-Surface Method (RSM) Cite This Paper. The complexity of the steam boiler makes it challenging to perform common measurements since several factors affect the performance of the boiler.
Downloadable! This article shows the application of an energy management system and the calculation of energy efficiency indicators to a pyrotubular boiler, following the guidelines of the ISO50001 standard. The actual energy consumption indicators, the theoretical consumption index, the energy baseline and the efficiency index 100 were evaluated based on gas consumption and steam production data.
Biomass has many advantages as a fuel for boilers: It's inexpensive, readily available in many regions, CO2 neutral, and its use warrants government subsidies. The fuel also presents unique
Abstract: In this paper a control strategy for demand side management of electric storage water heaters is presented. The proposed algorithm reduces load variations, during any given optimization period, taken into account the base load. The algorithm uses the energy consumption model of the water heater as an input.
Wastewater Treatment, RO, Operation Optimization, Process Design, Contaminant Removal, INTRODUCTION There is an increasing use of reverse osmosis (RO) in the reclamation of wastewater. Relative to other technologies, the main drivers for this include the low energy consumption of RO and the high rate of contaminant removal.
What is steam thermal cycle efficiency, and what affects the efficiency? These are questions that all steam system managers must be able to answer. The average steam system thermal cycle efficiency is 56.3%, which means that 43.7% of the energy consumed in boilers is wasted or lost. It is impossible to use all the energy input into the boilers.
This raises the requirement of sootblowing optimization strategy to determine which portions of the boiler to clean and on what schedule. The objective of this study is to develop a sootblowing optimization system that uses thermodynamic model and artificial neural networks model to predict the effectiveness of heating surfaces.
