Product Description: The rectification plan for coal-fired boilers above 20 tons before October 31, 2016, has been announced with four options: 1. Grid connection: Priority grid connection for boilers meeting the conditions. 2. Natural gas: Priority use of natural gas where pipeline networks are available. 3. Installation of desulfurization and denitrification equipment: Adding such equipment without replacing the coal-fired boilers. 4. Semi-coke: Retrofitting coal-fired boilers to use the clean energy source—semi-coke. Industry experts recommend that among the four options, grid connection should be prioritized for eligible boilers. For boilers ineligible for grid connection, retrofitting coal-fired boilers into semi-coke boilers is the preferred choice. This approach significantly reduces equipment investment costs, substantially lowers boiler operating expenses, and fully complies with environmental emission standards. The promotion and use of semi-coke boilers have given hope to manufacturers using coal-fired boilers. Our company, Shaanxi Weinan Fandel Boiler Factory, recognizing the substantial demand in this environmental sector, leveraged the strong capabilities of our parent group and Fandel’s unique technological R&D advantages to tackle technical challenges. Addressing issues such as low volatile matter in semi-coke, delayed ignition, and the presence of unburned carbon particles in the exhaust, we conducted in-depth research and continuous innovation based on existing chain grate boilers. We developed a complete set of semi-coke combustion technologies, thoroughly resolving these problems, and created a new environmentally friendly semi-coke boiler, along with dust removal equipment specifically designed for semi-coke boiler characteristics. Since the burner structure of semi-coke boilers is specifically designed and manufactured for the properties of semi-coke—high fixed carbon, low volatile matter, difficulty in complete combustion, and challenges in ignition—it differs from the burner structure of ordinary coal-fired boilers. Therefore, ordinary coal-fired boilers cannot burn semi-coke. Attempting to burn semi-coke in coal-fired boilers may result in issues such as poor combustion and flameouts, extremely low combustion efficiency, reduced boiler output, high energy consumption with low efficiency, increased operating costs, and disruption of users’ normal heating needs. Shaanxi Weinan Fandel Boiler Factory has specifically developed a new environmentally friendly semi-coke boiler and designed retrofitting solutions for coal-fired boilers to convert them into semi-coke boilers, along with customized dust removal equipment. This ensures that after retrofitting, the semi-coke boiler is easy to ignite, easy to seal, and achieves full combustion of semi-coke. Key features include: - Internal heat exchange tubes designed as threaded smoke tubes, improving thermal efficiency by 5% and featuring self-cleaning functionality. - Oxygen-enriched waste heat preheating for combustion assistance, increasing thermal efficiency by 3% and extending the service life of the grate. more>

Product Description: As a clean fuel, blue-coke produces lower levels of SO2, NOx, dust, and heavy metals during combustion compared to raw coal. Its post-combustion emissions meet environmental standards and have been recognized as a clean energy source by the National Development and Reform Commission and the Hebei Provincial Government, without consuming coal usage quotas. Blue-coke has a high calorific value of 6,200 kcal/kg, an annual production exceeding 100 million tons, and a highly competitive price. However, due to its low volatile content and unique carbon particle structure, it faces challenges in ignition and complete combustion in conventional boilers, significantly limiting its widespread application in industrial boilers. The blue-coke boiler modification by Shaanxi Fandelī Boiler features a simplified water circulation system and a rationally designed pressure-bearing structure, ensuring safe operation under proper water quality conditions. The combustion equipment of the blue-coke boiler adopts a quick-installation grate, manufactured and assembled in the factory, and can be directly installed on the foundation after transportation to the site. With its rational and compact structure, low steel consumption, and superior performance, weight, and dimensions compared to domestic boilers of the same capacity, it demonstrates significant advancements. Supply of blue-coke boilers: energy-saving and environmentally friendly fuel boilers. I. Criteria for Evaluating Modification Results Generally, the success of a boiler modification is judged based on steam pressure or steam flow. 1. Steam Pressure: The modification is evaluated by comparing the time taken for the boiler to reach the required steam pressure from a cold start before and after the modification. 2. Steam Flow: Professional institutions use specialized equipment to measure the steam flow under rated or operational conditions. The modification is deemed successful if the post-modification steam flow meets or exceeds the pre-modification measurements under the same conditions. more>

Product Description: The JFADW-05K power vehicle is a trailer-mounted AC/DC power supply unit. It utilizes a diesel engine as the primary power source to drive a generator, producing medium-frequency power. Through an external commutator, DC power is generated. The entire generating set and electrical control system are mounted on a trailer chassis. This vehicle can independently output both AC and DC power. Its working principle is based on power electronics technology, typically employing two core components: inverters and rectifiers. The main function of the inverter is to produce adjustable AC power from a DC source, while the rectifier converts AC power back into DC power.When providing support for aircraft using 28.5V power, in 28V mode, it can output DC 28.5V for power-on and startup procedures. For aircraft requiring 115/200V 400Hz power, in 115V mode, it can output AC 115/200V for power-on and startup, and can also supply AC 36V for in-situ testing. When supporting aircraft that use both 115/200V 400Hz and 28.5V power, in 28V mode, it can output AC 115/200V and DC 28.5V simultaneously for power-on. While one aircraft is starting with DC 28.5V, another can continue receiving 115/200V power until the startup process is complete.This product has extremely low environmental requirements and can operate normally even at altitudes of 3000 meters and under low-temperature conditions. Both the diesel engine and generator are nationally certified products, with emissions meeting environmental protection standards. Operating this vehicle does not require special safety measures, ensuring operator safety. more>
