Temperature sensors at Different stages of Cement Process
Temperature is a crucial process parameter in the manufacturing of cement. The correct monitoring of temperature at various stages of the process - Kiln Motor-bearing, Conditioning tower, Flue discharge, Preheater cyclones, Smoke-box and fuel storage determine the quality of clinker and the final product. Also, they help to detect at an early stage any overheating which may lead to malfunctions. Since the cement manufacturing process involves corrosive and harsh environments, the sensors employed should have strong resistance to adverse process phenomenon. TIPL temperature sensors are tested to comply with heavy vibrations, rapidly changing temperatures, abrasive discharges and corrosive gases to ensure the plant operator does not have to worry about maintenance !
Jammed Cyclones In Preheating Process
Cyclones are basically used to clean up the dust-laden gases leaving simple dry process kilns. If, instead, the entire feed of raw meal is encouraged to pass through the cyclone, it is found that a very efficient heat exchange takes place: the gas is efficiently cooled, hence producing less waste of heat to the atmosphere, and the raw mix is efficiently heated. This efficiency is further increased if a number of cyclones are connected in series. The number of cyclones stages used in practice varies from 1 to 6 (usually 5) and the temperature of material is around 900 Deg C.
Clinker Cooler Optimization
The clinker cooler is an essential part of a cement plant. Its function is to cool down the red hot clinker discharged from the kiln. Various designs of clinker cooler are under use in the industry, of which, the grate coolers are the most common. In a grate type clinker cooler the clinker at temperature as high as 1350°C falls on a series of stationary and reciprocating grates. Pressurized cool air is made to flow beneath the grates, which takes up most of the heat of the clinker as it rises and finally circulated to the preheaters. The clinker is usually cooled at rapid rate and brought down to temperature around 150°C. This is a necessity since the clinker has to be conveyed over rubber belts, to silos or grinders. Faster cooling rate of clinker is also important because it is a determinant factor which decides the strength as well as setting rate of cement and grindability of clinker.
Busbar Temperature Monitoring
Nearly, In every factory, shopping mall, airport, office complex and electrical room providing power distribution throughout the facility. The power distribution system usually includes high voltage metal-clad switchgear, transformers, low voltage switchgear and panel-boards. A fault or failure in anyone of these components can result in power outages, loss of productivity, and evenfire or explosions. Overload, phase imbalance, power factor, corrosion and poorelectrical connections all result in the generation of heat. Any generation of heat isan indication of loss of energy and wasted power. Heat also contributes to ashortening of the life of the equipment by up to 85%.These conditions can result from a fault.
Radar Level Application for Coal Silo
The usage of coal silos is to store coal, the primary fuel for firing the kiln and the preheater in a cement plant. Coal Silos are usually constructed of steel, but concrete is also used. silos are circular, square, or rectanglar in cross section and generally designed for a three- or four-day capacity. The hoppers should be designed for mass flow to eliminate static coal deposits. The bin outlet should be large enough to prevent arching or plugging. All bins should be self-cleaning, and internal surfaces should be kept free of stiffeners, weld strips, or flange surfaces. For explosion venting design, many factors must be considered. The National Fire Protection Association (NFPA) Guide for Explosion Venting should be used in evaluating each installation. Explosion venting provides relief for explosion force build-up inside the bin and limits the damage should an explosion ever occur.
