In view of the local cracking and leakage water-wall pipe Subcritical Boiler in a thermal power plant, mechanism water wall was studied by means macroscopic analysis, chemical composition metallographic structure, Brinell hardness test, tensile test at room temperature scanning electron microscopy. The results show that there is no misuse materials or unqualified cracked leaked pipe. There are ...

Our world and every person require a huge amount of energy, both electric thermal, which are produced mainly at various types power plants, but mostly on thermal. During the production electricity heat thermal plants different potential hazards occurring: chemical, environmental, fire or explosion. In accordance with identified possible six emergency situation scenarios suggested. The failure t...

Cement production is an energy-intensive process, so that the cement industry occupies a top position among other energy-consuming industries. Among the equipment used in cement industries, boilers are one of the energy-consuming equipment. Boilers are among the common heating equipment in industrial, commercial, and institutional facilities. In this paper, the performance of thermal oil bo...

The 660 MW ultra-supercritical circulating fluidized bed (CFB) boiler, which is the maximum capacity and largest scale boiler in world has entered construction stage China. This study established a full-scale dynamic simulation model of at 100% continuous rating (BMCR) condition. consists an air-flue gas system, water-steam ash circulation system. “core-annulus” gas-solid two-phase flow structu...

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...

A quench boiler is the key equipment in ethylene production for rapid cooling of high-temperature cracking gas. In boiler, heat transfer occurs between hot gas passing through inner exchange tubes with an average temperature 385 °C and cold water (or water) 350 °C. Required double-pipe transfer, special tubesheets formed by welding flat-round side are difficult to design, as no suitable design ...

The Pulverize is a major part of the boiler combustion system and an important part in the system of steam power plant (PLTU). Pulverizer plant serves to break chunks of coal into the coal ash was then fed to the burner. Type of feed coal into a pulverize is cleaned with a value product pulverize optimum 30%. The percentage of this value greatly affects the production of steam in the boiler. Th...
