Amreyah Cement Company currently powers its three clinker lines with oil and wants to switch to coal and petcoke which are easier and less costly to source. The mills comply with the latest ATEX directives to avoid all risks of explosion. Both ball mills are rated for outputs of 35 t of coal per hour. Pfeiffer MPS coal mills are in operation worldwide. The company has its own manufacturing facilities
Petroleum coke abbreviated coke or petcoke is a final carbon-rich solid material that derives from oil refining and is one type of the group of fuels referred to as cokes.Petcoke is the coke that in particular derives from a final cracking process—a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains—that takes place in units termed coker units.
& 0183;& 32;Most explosions in coal mill plants have their initial ignition lo ion within the mill chamber. This is because the mill chamber is the section of the plant in which the conditions for the ignition of air and dispersed fuel are most favourable. Here the risk exists that tramp metal can get trapped in the grinding media. Grinding

Explosions in coal mill systems are confined explosions which means that the pressure effects must be dealt with by protective techniques to prevent the pressure rise from exceeding the strength of the plant either by venting the expanded air into the atmosphere or by suppressing the combustion. Smaller sections of the plant such as intermediate hoppers can be built with the

& 0183;& 32;3.2 Field Test of petcoke and Indian sub bituminous coal Petcoke and Indian coal were fired separately in CFB test facility. Limestone was added along with petcoke for in- situ sulphur capture. Particle size distribution of the feeds are shown in Figure 3. Mean particle size of petcoke limestone and Indian coal are 417 & 181;m 143 & 181;m and 400 & 181;m respectively. It can be seen that over 55 %
Petcoke differs from coal most obviously in its almost total lack of ash and its relatively high sulfur content. While the latter is a significant problem for power generators it can be less so for cement manufacturers because the alkaline conditions in a preheater scrub SO 2 out of the exhaust gas. However there is a distinct trend towards the installation of separate SO 2 scrubber units. Petcoke
Coal dust is a fine powdered form of coal which is created by the crushing grinding or pulverizing of coal. Because of the brittle nature of coal coal dust can be created during mining transportation or by mechanically handling coal.It is a form of fugitive dust.. Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier to handle.

Mill explosions will only occur when three conditions exist: sufficient oxygen ≥12 per cent O 2-in-air the presence of an ignition source >30mJ and air-suspended coal dust in a bandwidth of 50-2000g/m 3. Safe operation of coal mills seeks to avoid these conditions and many monitoring systems exist to provide fire and explosion protection.

Coal should be kept as dry as possible sprinklers are not recommended A sufficient ventilation system should be provided to reduce the chance of methane and in case of fire smoke build-up and for explosion venting requirements. Ventilation should be provided at the apex to take advantage of the chimney effect. Coal storage meets environmental responsibility.
