The basic need of living things that is very important and cannot be separated water. Various industrial activities require water for processing such as the palm oil industry, industry required to use with good conditions proper chemical treatment. power plant at PT. Socfindo Seunagan, requires steam needs from boiler. Boiler a closed place produce heating boiler system, among others, consists ...

An indirect, sensitive and accurate method for the determination of trace amounts of hydrazine is described. In this proposed the spectrophotometric method is based on its reduction properties of hydrazine with a known concentration of potassium permanganate to reduce the colour. The absorbance of unreduced permanganate is measured the colour difference at different wavelengths 546 and 526 nm w...

Hydrazine in water samples is determined by constant current chronopotentiometry in porous carbon electrodes. Hydrazine in alkaline solutions is oxidised to nitrogen in the pores of the electrode by constant current. Two types of electrodes made of reticulated vitreous carbon (RVC) were used, one fabricated from crushed RVC particles, the other with the original RVC material of 100 ppi porosity...

Thousands of medium and low steam boilers hot water operate in the country's industry, municipal energy agriculture. Their reliable operation is largely determined by maintenance a rational water-chemical regime. The main problems source are presence dissolved oxygen, iron ions, salts calcium, magnesium.
 aim work to analyze existing technologies equipment for treatment different types boi...

As the energy cost is rising steadily and the environmental pollution is becoming an important issue, the roles of process plant boilers like that of the sugar plants boilers need better understanding as they can be made to operate in either energy conserving or bio-mass conserving modes. However, practical models of the plants need to be developed before any effort at optimization and cogenera...

We model a steam-boiler control system using hybrid automata. We provide two abstracted linear models of the nonlinear behavior of the boiler. For each model, we de ne and verify a controller that maintains the safe operation of the boiler. The less abstract model permits the design of a more e cient controller. We also demonstrate how the tool HyTech can be used to automatically synthesize con...

The present paper deals with the optimization of a multi-energy district boiler (La Rochelle, France) which supplies domestic hot water and heats residential and public buildings, using renewable and fossil resources. First, a combination of white, grey and black boxes was used to model the plant, thanks to a modular approach. Next, a stratified thermal storage tank was modelled and completed t...

This paper presents an approach to analyze events leading to pluggage of a boiler. The proposed approach involves statistics, data partitioning, parameter reduction, and data mining. Two independent data mining algorithms have been applied to detect both static and dynamic relationships among the process parameters. The multi-angle data mining approach increases the ability to locate rare event...
