hazard identification and risk assessment of 2300mw thermal power plant with their control measures to optimize the risk | springerlink
In India, a coal-based thermal power plant generates 93,918.38MW approximately of total energy production. A coal-based thermal power plant converts the chemical energy of the coal into electrical energy. The company is operating coal-based 2300MW thermal power plant which is driven by steam and generates electricity by expanding and raising the steam in the boilers and coupling the turbines to the generators which converts mechanical energy into electrical energy. In this operation, there are many stages and processes that steam and coal have to pass through which involves various unsafe acts and sometimes unsafe conditions while operating and handling equipment or processes that could lead to potential failure of the equipment, interrupting the normal working of the plant that ultimately have a detrimental effect on the production of the plant, probability of accidents, injury to human lives, damage to property and environment becomes quite high. For protecting plant from such condition, a quantitative risk assessment can be very useful as it helps in focusing and prioritizing the risk which are more severe and catastrophic. In this project, a HIRA is prepared for each process, and risk factor has been calculated by assigning frequency of occurrence and severity of the hazards. The finding of the study suggested the possible control measures and corrective actions to reduce or eliminate the risk that can be used by power plant in preventing accidents from occurrence.

coal crusher types- impact& double roller crusher
Coal crusher, also known as double stage crusher, is a highly efficient crushing equipment. It is a new type of equipment developed for the coal industry, and it mainly crushes high moisture coal. Besides, it is mainly used to crush coal cinder, slag, shale, coal gangue and other materials. And it can be applied to building material, highway, railway, mining and other industries.
This type of crusheris better than traditional crushing equipment. Once the material moisture content is more than 8%, the traditional crusher will be blocked and the motor will be burned. Fortunately, Aimixs coal crushing and screening plant can solve the problem. The biggest advantage of Aimixscoal crusher is that it can also have normal production even on rainy days. Even the moisture content of the material is high, the material will not be blocked when it is crushed, because itdoes not have a sieve bottom. Besides, the crushed material of the crusher is very uniform and can be controlled below 2 millimeters, and the traditional machine crusher must add a sieve to screen out the ideal product size.
The crusher has two sets of rotors which connect with each other. And when the itworks, the two rotors rotate at the same time under the drive of two motors. In the crushing cavity, materials which be crushed by the first rotor will be crushed immediately by the second rotor again. Materials in the inner cavity will collide and smash each other rapidly. That means the materials will be crushed by the hammer and other materials. After crushed, materials will be discharged. And this is the working principle of a coal crusher plant.
Diameter of feeding inlet(mm): 400*1080
Max. feeding Aggregate Size(mm): 350
Power(kw): 4P 45-55
Total weight(T): 12
1. Without the screen and grate, Aimix coal crusher for sale can crush high humidity materials. And the crusher has no any requirement for materials moisture content. At the same time, it can also crush dry materials. Besides, ithas large output, small noise, and high crushing efficiency.
2. Thecrusher adopts the new type shift clearance technique. The worn hammer of the crusher does not need to be replaced, because the position of the hammer can be adjusted. As long as the gap between the hammer and the liner is appropriate, the finished material size will be uniform. In addition, the lining board is also adjustable. So, in general, a hammer of thecrusher can replace three ordinary hammers. Moreover, the service life is much longer than that of traditional crushing equipment.
3. The coal crusher machine has centralized lubrication system, that means oil can be injected without stopping machine. In addition, it uses hydraulic system to open the shell, and the shell can be easily opened by one people. Both machine maintenance and spare parts inspection are very conveniently.
As a professional crusher supplier, Aimix has various type of coal crushers and other impact rock crusher machines for sale. In order to meet the needs of different customers, we have developed and produced many types of crusherequipments. In addition, we have different kinds of coal crusher specifications.
As for the type, we have several series, such as ZPC series, HD series, the third generation SCF series and so on. The main situation of these crushers are same, but they have small differences. You can ask us online for more detailed informations.
In addition, every type of crusher has many specifications. For example, SCF crusher has various specifications: SCF600*400, SCF600*600, SCF700*800, etc. The same point is, the water content of the crushed materials should be less than 25%. But their input size and output size are different. You can choose different type or specification of crusher to meet your actual needs.
