The fundamental ingredient in concrete is portland cement. The cement manufacturing process requires a great deal of energy to heat the mixture of raw materials in a cement kiln. The main source of toxic emissions from a portland cement plant is the kiln. The treatment of kiln exhaust is similar to most incinerators processes. Scrubbers are the best choices for control of acid gases, fine particulate, heavy metals as well as dioxin and furans. The MACT II regulations, yet to be finalized, for cement kilns are...
ECOGRACE produce all bag filter bags for emission control for industry like gypsum factory, asphalt mixing site, tabacco factory,cement mill, cement kiln, steel plant blast furnace,biomass boiler, coal fired boiler.etc.
The United States Environmental Protection Agency (EPA) has two stack testing methods for FTIR gas analyzers. Method 320 is an FTIR method for measuring wide range of organic and inorganic pollutants. Method 321 is a specific version for measuring hydrogen chloride HCl at cement kilns producing Portland cement. These methods define a quality assurance and control processes for verifying the accuracy of the results. The requirements for analytical equipment and software are defined on 40 CFR Part 60 Appendix B...
The manufacture of cement combines a variety of raw ingredients such as limestone, clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. The resulting raw mix is fed into a cement kiln which heats them to extremely high temperatures of about 1400 C to 1500 C. The abrasiveness of the material is a major factor on the wear of equipment and the extreme high temperatures of the process require specialized equipment.
One way in which valuables within waste can be utilized is by using it as fuel. Refuse derived fuel (RDF) is a term that applies to materials with a high calorific value (typically around 18 Mega joule per kilogram) that are removed from waste streams. Beneficiaries of this material are cement kilns to power plants.
With the growth of population and rapid development of the city, more and more municipal waste are produced and seriously influence our live and environment. Municipal waste also know as MSW, domestic waste and household refuse. Municipal waste should be shredded before burying or burning to save more storage space or to lower the transport cost for collecting.
Harden has offered hundreds of excellent municipal waste shredding solutions for both individual or association project. Harden shreds any waste for a...
Waste to energy: The use of refuse derived fuel (RDF) is part and parcel of today`s regulated waste disposal. Using a selective treatment process, fractions high in calorific value are separated off from commercial and industrial waste, creating a marketable product. Depending on calorific value, composition and particle size, this fuel is used in industrial fluidised bed firings, in cement kilns and in RDF power plants.
Taking measurements on rotating equipment, such as a kiln or rotary table, usually requires a complex and expensive system of cabling. Even taking precautions and using specialized equipment doesn’t eliminate cable tangles and breaks.
The SureCross Wireless Network eliminates complexities associated with data acquisition from rotating and moving machinery such as a rotating kilns in cement or composting industry. Crucial temperature data is acquired using a thermocouple and transmitted from the FlexPowered...
Cement is the main ingredient of concrete, which is the most common building material in the world. Cement industry is one of the biggest CO2 emission producers mainly due to the huge production capacities and calcination process, which is an important part of cement production. Cement manufacturers need to monitor these emissions continuously according to local emission regulations. Read about our solutions to the cement industry!
Removal of acid gases and particulate from cement, brick and other product kilns. Mineral product dryers including coal. Hot mix asphalt plant particulate control. Sulfur dioxide and hydrochloric acid gas removal.
Nomex filter bag for higher temperature dust filtration ,widely applied in Asphalt mixing plant ,Kiln smoke in cement plant ,steel plant blast furnace smoke and so on. NOMEX filters offer one of the best total economies in a filtrationsystem because of higher air to cloth ratios, higher temperaturecapability, and a long wear life.
Oxygen is used during a furnace campaign to increase throughput, at the end of a furnace campaign to extend the useful life and reduce total emissions, and for new furnaces maximize throughput return on investment (ROI). In all cases, energy use, NOx and particulate emissions are reduced. Every type of glass, from beer bottles to sophisticated computer flat glass, has seen extraordinary quality benefits with the increased use of VPSA oxygen.For fiberglass and mineral wool smelter production, all the same economic...

Stack emission monitoring encompasses the processes of testing, sampling, and analyzing flue gases to track and measure the properties of the gas, including temperature, flow, and pressure. Our MAC moisture analyzers are well-known for their efficiency in environments where regular stack emission monitoring is required, such as:
A key issue in the measurement of the products of combustion in Cement and Lime industries is the high levels of particulates. The Procal 2000 in situ analyser`s heated probe option is especially suited to this industry as it efficiently deals with variations in process temperature, keeping the probe above the sample dew point and safe from corrosive condensate.
Our shredding solutions enable you to optimally recycle waste into substitute fuels / alternative fuels and ensure high quality by producing a homogeneous granulate free of foreign objects. The goal of recycling is to use the valuable energy contained in the waste and to substitute the use of fossil fuels. During the recycling process the portions with a high calorific value are separated from the commercial and industrial waste and turned into a marketable product. Depending on the calorific value and the...
Current Total VOC MeasurementsThe most common, and current standard, method for measuring Total Volatile Organic Compounds (VOC) is the use of a Flamed Ionisation Detector (FID). This gives a representative value of the total carbon content of a gas stream, as the FID cannot tell which specific organic compounds are present.
Kurz Thermal Insertion Mass Flow Meter systems provide proven accuracy and reliability in the most difﬁcult of EPA Title IV applications with the ability to survive for long periods of time without maintenance.
