Model Of Efficient & Clean Use Of Coal Under Depression Of Coal Industry
In response to national's advocacy on clean use of coal, an energy company in Shandong purchased 4 MTW European Mills (secondary phase) for coal powder preparation from SBM. Through atomization of micro-coal, the coal will be supplied to industrial boilers as fuel. The use of coal powder can increase the combustion efficiency and thermal efficiency of boilers greatly and bring economic profits as much as hundreds of millions yuan. Undoubtedly, this is the model of efficient and clean use of coal.
Project Profile
Design Scheme --- Installation and commissioning
The energy company is a research and development base focusing on the efficient and clean use of coal in Shandong Province. The technology of micro coal atomization, its result of independent research and development, can boost the transformation and upgrading of coal industry effectively. The so-called micro coal refers to the coal powder meeting the standard of fineness after coal is ground by mills. Through the technology of micro coal atomization, the fuel can mix with air fully to form a rotary vortex and then the fuel enters the industrial boilers and burns in suspension inside. The use of thermal system, monitoring and controlling system and exhaust purifying system achieves the efficient combustion with emissions reaching the emission standards of gas. Except for the increase of input-output ratio, the clean coal production which used our 4 MTW215 European Mill (Secondary Phase) and other auxiliary machines reduced the emission of dust, SO2 and nitrogen oxides greatly.
Project Background
According to the report released by China National Coal Association, over 70% coal companies are suffering financial losses. The severe situation of coal industry makes transformation and upgrading urgent. So, under the premise of controlling coal consumption, how to increase economic profits of tradition coal firms, how to use coal resource efficiently and cleanly and how to reduce environment pollution incurred by coal combustion have been the common problems among coal companies.
Depression of Coal Enterprises
According to the report released by China National Coal Association, over 70% coal companies are suffering financial losses. The operation faces difficulties and the situation of this industry is severe. Meanwhile, China actively advocates and supports the market-oriented reform and structural management in coal industry by releasing related policies. Under the condition of balancing supply and demand, it is urgent for coal industry to upgrade.
Support of National Policies
The Action Plan of Clean Use of Coal (2015-2020) released by China National Energy Bureau clearly stipulates that by 2020 the use ratio of efficient boilers must reach 50% at least in some areas. According to the fifth plenary of CPC's 18th Central Committee, the clean use of fossil energy must be put on the schedule, coal included. So it can be concluded that the promotion of efficient and environmental coal powder boiler will be a key energy-saving technology in China.
Support from Local Government
To stimulate transformation and upgrading, Shandong government subsidized some major PPP projects. Meanwhile, Shandong province launched an action plan (2015-2018) to promote efficient and environmental coal powder boilers. The plan showed that the efficient coal powder boilers can be used for heat supply and steam supply and therefore the boilers should be popularized and applied as soon as possible.
Environmental Pressure
Using coal briquette as the fuel, traditional industrial boilers discharge a great deal of dust and contaminant. However the use of coal powder makes local area free from pollution with all emissions below the national standards. The emission of dust is ≤30mg/m3, SO2 ≤100mg/m3, nitrogen oxides ≤200mg/m3.
Economic and Environmental Profits Brought by Combustion of Coal Powder
The use of coal powder boilers can burn over 98% of coal powder. Meanwhile, compared to the traditional boilers, the coal powder boilers can save energy by over 30% while heat efficiency keeps above 90%. The operation costs can be reduced by 20-30%. What's more, the unit cost of fuel of coal powder boilers occupies one third of that of gas boilers only.
Configuration Of Production Line
Main Equipment of Coal Preparation SystemMTW European Mills (Secondary Phase)
The complete system of MTW Series European Mills is advanced. The mill is equipped with the bevel gear integral transmission device, inner thin-oil lubrication system, monitor of oil temperature. Meanwhile, the mill boasts small occupation of land, low total investments, low operation costs, high efficiency and environment protection. Compositions of Coal Preparation System: Raw material bin, weighing coal feeder, MTW European Mill, powder collector (anti-explosive dust collector), fan, de-iron separator, drying system, conveying system, etc
Auxiliary Machines of Coal Powder Preparation
Nitrogen Making System
Firstly, air is compressed by air compressor. Then air enters the efficient oil remover where most oil, water and dust would be removed primarily. After that, the refrigerated-typed air-dryer removes most moisture and the powder filter removes the dust. Then the air enters the air storage tank. After buffer, the air is sent into the nitrogen making machine filled with absorbents. Clean compressed air enters to the adsorption tower from the bottom and then the air diffuses under the action of air diffuser. In the adsorption tower, the oxygen and nitrogen would be separated and the nitrogen would be sent to the tank for storage.
Fire Extinguishing System
The Action Plan of Clean Use of Coal (2015-2020) released by China National Energy Bureau clearly stipulates that by 2020 the use ratio of efficient boilers must reach 50% at least in some areas. According to the fifth plenary of CPC's 18th Central Committee, the clean use of fossil energy must be put on the schedule, coal included. So it can be concluded that the promotion of efficient and environmental coal powder boiler will be a key energy-saving technology in China.
Pneumatic Conveyor
Pneumatic conveyor is mainly responsible for the transportation of coal powder. It can send the coal powder into the finished product bin from a long distance.
Intelligent Centralized Control System
Through multiple communication technologies to read PLC or ECS and collect the operation situations of equipment and through directives to control the equipment, centralized control system can achieve remote control, record and analysis of machine operation and print the reports of equipment operation.
MTW European Mill has specialized intelligent control system. It takes ESC to control operation intelligently. And apart from the central control, it can control operation remotely. By communication tools like smart phones and Ipad, the operation situation of production lines can be checked out.
Technological Analysis
Raw coal is sent by quantified feeder to the scrapper conveyor which then sends coal to the dryer for moisture removal. Then the coal enters the closed storage bin through closed scrapper conveyor. The coal is then transferred to the raw material bin of powder preparation system and by weighing coal feeder the coal is fed into MTW215 European Mill. After that, the coal powder undergoes the classification and following this step the coal powder enters into the powder collector along the tube (The remaining air is collected by impulse dust collector). The finished coal powder collected enters the elevator under the action of spiral conveyor. Finally, the coal powder is elevated to the coal powder storage bin. And if there is any need, the finished coal powder will be transported by the tanker. The complete set of this system is equipped with the nitrogen making system and CO2 system to avoid explosion and to extinguish the fire if necessary. Meanwhile, anti-explosive valves are installed at the key parts in avoidance of possible damage to the equipment.

Introduction of Micro Coal Atomization
The key of this technology is atomizing micro coal by mixing it with the air vortex repeatedly. Mixing the micro coal (200meshes) with the high-speed air vortex is the first step. The mixture will be sent into the boilers and burn in suspension there. The use of thermal system, monitoring and controlling system and exhaust purifying system achieves the efficient combustion with emissions reaching the emission standards of gas.
Through selection, drying and grinding, the micro coal used in the efficient coal powder boilers can become the powder (200 meshes). Centralized management and unified delivery not only ensure the quality of coal powder but also eliminate the scattered coal piles. The boilers are characterized by high efficiency, environment protection, clean emission and high automation. Therefore, the promotion of efficient coal powder boilers plays an important role in clean use of coal, environment improvement and the growth of environment-friendly industries.
