In order to reduce the volume fraction of H2S in water wall area four-corner tangential boiler and achieve purpose alleviating high temperature corrosion wall, a thorough test was carried out on 600MW boiler. The results show that under load is obviously more serious than low load, front other walls, furnace downstream burner generally higher walls. Other areas. reason for this phenomenon unifo...

Boilers are one of the most used units for both heat generation plants and industry systems. Their operation is subjected to different working loads maintenance requirements. Exploitation experience points out critical boiler zones where failures break downs typically occur. This paper analyzes in hot water fire-tube boiler. Experimental procedure was performed on model this type boilers its el...

This paper studies a planning problem for heating water. Hereby, boilers (e.g. gas or electric boilers, heat pumps or microCHPs) are used to heat the water and store it for domestic demands. We consider a simple boiler which is either turned on or turned off and has a buffer of limited capacity. The energy needed to run the boiler has to be bought on a day-ahead market, so we are interested in ...

A district heating system is an eco-friendly power generation facility with high energy efficiency. The boiler water wall tube used in the exposed to extremely harsh conditions, and unexpected fractures often occur during operation. In this study, a corrosion failure analysis of was performed elucidate mechanisms. study revealed that overheating by flames cause tube. With increase temperature l...

partial least squares modeling as a powerful multivariate statistical tool was applied tothe simultaneous spectrophotometric determination of silicate and phosphate in aqueoussolutions. the concentration range for silicate and phosphate were 0.02-0.6 and 0.4-3 μg ml-1,respectively. the experimental calibration set was composed with 30 sample solutions using amixture design for two component mix...
