Small and medium caliber instruments are commonly used in solid-liquid biphasic and other difficult to measure fluids or high requirements, such as measurement of paper industry pulp and black liquor, non-ferrous metallurgy slurry, coal slurry, chemical industry, strong corrosive liquids, and iron and steel industry, blast furnace cooling water control and monitoring leakage of ...
Coal washing is a process through the impact of water flow, raw coal with different components and specific gravity is separated into different grades. It can remove dust and waste rock and reduce the ash and sulfur content. Coal washing is an indispensable link in coal processing. The coal ...
Modern PCI plant designs use dens phase conveying systems to transport pulverized coal from the storage area to the blast furnace, reducing nitrogen consumption, abrasion and stabilizing coal flow. ...

The burners are operated with lean air to produce carbon monoxide required for reduction of the zinc oxide to pure zinc. Boliden uses MECONTROL Coal to control fuel flow and fuel concentration to the burners for a controlled combustion. ...
MECONTROL Air The MECONTROL Air system was used to measure gas flows in the cement making process namely Raw Mill and Coal Mill gas flow, TAD, Cooler Exhaust and Cement Mill gas flows. ...
With regenerative air heaters the fly ash carryover is a problem for other flow measurement devices. Other Luminant plants had previously tried pitot tubes, hot wire anemometers and other flow devices unsuccessfully. Starting in 2004 PROMECON had supplied primary air flow measurement for the coal mills on multiple lignite fired ...
For the new MPP3 units PROMECON supplied MECONTROL Air and MECONTROL Coal systems for the boiler and MECONTROL UBC for the fly ash handling. ...
The high moisture of the raw material require more than normal gas flow quantities through the mill for drying. The power consumption for the mill fan is about 60% of the total power consumption of the grinding system. The aim was to control and minimize the air flow through the mill. Before the Genevieve project was launched Holcim tried measurement of the ...
The heart of each power plant is the boiler where the sun energy captured in form of hard coal will be released and converted into thermal energy. Modern multi stage burners combust the pulverized coal supported by primary, secondary and tertiary air. ...

This paper describes computational fluid dynamics (CFD) simulations conducted to investigate the effectiveness of N2 injection in an active panel and a sealed longwall gob area to prevent and suppress spontaneous heating of coal using various injection locations and flow rates. In the active panel simulations, a single longwall panel with a bleederless ...
The primary determinants of the value of a coal company are its cash flows and earnings, which is dependent upon the quantity and quality of the coal it produces and coal selling prices; future production potential, which is described by its reserves; and its inventory of capital assets, mining equipment, infrastructure, and ...
In this research paper, predictive modelling of NOx emission of a 210 MW capacity pulverised coal–fired boiler and combustion parameter optimisation to reduce NOx emission in flue gas is proposed. The effects of oxygen concentration in flue gas, coal properties, coal flow, boiler load, air distribution scheme, flue gas outlet ...
The treatment plant currently operates 5 days per week, approximately 9 hours per day, to treat water that is collected throughout the previous day. The total flow of water varies seasonally, but on average the plant treats about 450,000 gallons per day. ...

Methane presents a pervasive risk in most coal mines, its dilution being one of the primary objectives of the ventilation system. Although many different types of detectors and techniques exist for quantifying methane, little is known about the qualitative aspects of methane, such as visualising how this gas flows from coal. Background Oriented ...
The bottom slot opening feeds the material to the belt to deposit the coal symetrically and centrally to develop an ideal belt loading. The center dome produces a vibratory action on the material to reduce the arching and induce the flow in the storage pile. ...
Precise, timely measurement of air, fuel, and gases is one way today's utilities can take action to protect themselves against rising costs and comply with increasingly stringent environmental requirements. Sierra thermal mass flow meters and control systems are designed expressly to fill these needs. They can make utilities more cost-effective in a variety of applications: ...
