Vanderlee Boiler (Image) | Xianyang Coal-fired Boiler Conversion to Semi-coke Boiler | Semi-coke Boiler
Negotiable
Category: Machinery & Equipment/Electric Heating Equipment/Medium Frequency Power Supplies
Company: 陕西德力能源科技有限公司
Product Description: At the same time, Vandelli Boiler, leveraging the inherent advantages of semi-coke while addressing its shortcomings, has fully utilized its benefits and employed proprietary technology to mitigate and resolve its deficiencies. This led to the development of a high-temperature gasification and pyrolysis combustion semi-coke boiler. The principle involves first gasifying the semi-coke to convert it into combustible gas, which is then burned to produce hot water, steam, or heat thermal oil. A key feature of this equipment is that gasification and combustion occur almost simultaneously within microseconds. The rectification plan for coal-fired boilers above 20 tons, announced before October 31, 2016, includes four options: 1. Grid connection: Priority given to boilers meeting grid connection conditions. 2. Natural gas: Preference for natural gas where pipeline networks are available. 3. Installation of desulfurization and denitrification equipment: Retrofitting existing coal-fired boilers with such equipment without replacement. 4. Semi-coke: Converting coal-fired boilers to use semi-coke as a clean energy source. Industry experts recommend that, among these options, boilers capable of grid connection should be prioritized for that solution. For boilers that cannot be connected to the grid, converting coal-fired boilers to semi-coke boilers is the preferred alternative. This approach significantly reduces both equipment investment and operational costs while fully complying with environmental emission standards. As a clean fuel, semi-coke produces lower levels of SO2, NOx, dust, and heavy metals during combustion compared to raw coal. Its post-combustion emissions meet environmental requirements and have been recognized as a clean energy source by the National Development and Reform Commission and the Hebei Provincial Government, exempting it from coal consumption quotas. Semi-coke boasts a high calorific value of 6,200 kcal/kg, an annual production exceeding 100 million tons, and highly competitive pricing. However, due to its low volatile content and unique carbon particle structure, semi-coke faces challenges such as difficulty igniting and incomplete combustion in conventional boilers, which has severely limited its widespread adoption in industrial boilers. more>

It has strong resolution, high measurement accuracy, and reliable performance, making it a commonly used displacement sensor for measuring shaft rotation angle.The code disc (grating disc) has several rectangular holes evenly distributed on a circular plate of a certain diameter. Since the photoelectric code disc is coaxial with the motor, when the motor rotates, the code disc (grating disc) rotates at the same speed as the motor. The detection device, composed of electronic components such as light-emitting diodes, detects and outputs several pulse signals. By calculating the number of pulses output by the photoelectric encoder per second, the current motor speed can be determined. (As shown below) more>

Category: Chemicals/Chemical Intermediates/Intermediate Compounds
Company: 烟台乐森机械设备有限公司
Product Description: Due to fluctuations in raw material prices, the specifications and prices may vary. For specific quotations, please contact our sales staff. Thank you.Our mining stemming machine really delivers when it comes to mud output speed! Look at these mud strips—one after another, they shoot out swiftly, keeping a fast and uninterrupted rhythm. You’ll see them pile up into a small hill in no time, with the progress bar shooting up. Just press a button and it starts running automatically—no more bending over or straining your back. It saves a ton of effort.Purpose of the Mining Stemming Extrusion Machine:The mining dual-hole stemming machine is primarily used to enhance safety and efficiency in mining operations. Its dual-hole design allows for the simultaneous processing of two different specifications of stemming material, accommodating blastholes of varying diameters.Power Specifications:Common power ratings include 3KW, 4KW, and 5.5KW. The power level determines the machine’s driving force and production capacity. A 3KW stemming machine has relatively lower power and is suitable for small-scale mines or operations with modest output requirements. The 4KW model offers moderate power, striking a good balance between performance and energy consumption, making it ideal for most standard mining operations. The 5.5KW version provides strong power, suitable for large-scale, high-intensity production, enabling rapid output of large quantities of stemming material and boosting work efficiency.Voltage Specifications:Common voltage options include 380V, 380/660V, and 660–1140V. Selecting the appropriate voltage is crucial and must match the power supply system at the mining site. 380V is a common industrial voltage, suitable for general surface operations or locations without special voltage requirements. Voltage specifications like 380/660V and 660–1140V are more often used in special environments such as underground coal mines.Output Speed:The typical output speed ranges from 20 to 22 meters per minute. Output speed directly affects production efficiency—a higher speed allows for more stemming material to be produced per unit of time. However, if the speed is too high, it may compromise the quality of the stemming material, leading to issues like uneven surface texture or inconsistent density.When selecting a mining stemming machine, it’s important to consider factors such as production requirements comprehensively—no waiting, no delays. This speed is perfect for rushing jobs and meeting tight deadlines. The machine is easy to use—place your order now! more>
