Various pollutants form in the cement manufacturing process, especially when alternative fuels and waste-derived fuels are used. Typically a cement kiln using these fuels is a required to monitor hydrogen chloride (HCl). Gasmet CEM II is EN 15267-3 approved for HCl measurement in 0 … 15 mg/Nm3 range.High process temperatures result in generation of more nitrogen oxides (NOx) than in typical municipal waste incineration.
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.
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...

Waste-to-energy through incineration of waste is an effective way of producing electricity and heat, at the same time getting rid of the possibly hazardous or unrecyclable waste. The waste can be incinerated at specific WtE plants or at plants with permission for co-incineration of waste at biomass boilers or cement kilns. The waste incineration plants are, however, governed by strict emissions regulations.
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.
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...
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.
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.
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.
Application: PPS (Ryton) Filter Bags are widely used in coal-fired boilers, waste incinerators, coking furnaces, kiln furnaces,Biomass Furnace ,chemical dry process of flue gas cleaning processes, also using, carbon black, powder collection, pneumatic conveying, cement industry, and more. When due to chemical attack and hydrolysis causes, Aramid cannot be used, PPS (Ryton) Filter Bag can be substituted.
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.
