This paper is concerned with calculating boiler efficiency as one of the most important types of performance measurements in any steam power plant. That has a key role in determining the overall effectiveness of the whole system within the power station. For this calculation, a Visual-Basic program was developed, and a steam power plant known as El-Khmus power plant, Libya was selected as a cas...

A system for handling up to 120 tons/day of municipal refuse has been developed for co-firing with coal in a spreader-stoker boiler at the Colum­ bus, Ohio, Municipal Electric Plant. This system is unique in that the refuse has undergone only shred­ ding to 90 percent minus 4 in. (10 cm) and magnetic separation of ferrous material. The refuse-handling system comprises: (1) a push-pit with a hyd...

Over a decade, coal-based thermal power plants are upgraded to operate at supercritical pressure conditions due its high efficiency and low emissions. Water wall panels of typical boiler structured spirally in the lower furnace vertically placed upper furnace. The spiral tubes inclined 19 22 degrees which fluid behaves as horizontal tubes. design water plays key role designing boiler. present w...

Superheater is for generating superheated steam from the saturated steam from the evaporator outlet. In the case of pulverized coal fired boiler, a relatively small amount of ash causes problems with ash fouling on the heating surfaces, including the superheaters. In the convection pass of the boiler, the flue gas temperature is lower and ash deposits can be loose or sintered. Ash fouling not o...

as part of the OptiEnR research project, the present paper deals with optimizing the multi-energy district boiler of La Rochelle (France) adding to the plant a controlled thermal storage tank. This plant supplies domestic hot water and heats residential and public buildings, using renewable and fossil resources. Due to the complexity of the district boiler as a whole and the strong interactions...

Generally, boiler feed water pumps are subjected to extreme mechanical and thermal stresses because of their huge siz...

Received Oct 21, 2017 Revised Dec 28, 2017 Accepted Jan 13, 2018 An embedded based power plant system is used for checking the environmental condition based on different sensor. The microcontroller is fixed inside the boiler which is a turbine, to monitor the status and the information is passed through GSM. In this project we proposed the main water tank supplies number of boilers. The water l...

In this paper we compare and discuss the performance of a boiler evaporator system when the system is controlled by a traditional PID-type strategy and when the system is enhanced by using fuzzy logic blocks to provide set-points for the system. The strategy used in fuzzy logic controllers (FLCs) is called fuzzy supervisory control and it generates set-points for the conventional controllers. T...

In this paper, we describe the implementation and usage of a simulation with graphical visualization for a steam-boiler [Abri94]. The simulation imitates the behaviour of the steam-boiler and can be controlled using a simple ASCII protocol. It reacts to defined commands and sends information about its state every five seconds. Furthermore, we describe the options available, the protocol which f...
