A few days ago, from the China Electrical Engineering Society organized in Beijing, the "Ha-pot self-developed 600MW supercritical boiler design program" review meeting came to the news, the 600MW vertical pipe ring water-cooled wall supercritical boiler independently developed by Harbin Boiler Factory Co., Ltd. has The advantages of reliable technology, high operational safety, low cost, etc., meet the needs of the national conditions, fill the domestic gap, reach the international advanced level, and will certainly make new contributions to the development of China's electric power industry. Lu Yanchang, chairman of the China Electrical Engineering Society, and academicians of the Academy of Engineering, Qin Yuxi and Huang Qili, attended the review meeting.
As a major coal-producing and coal-producing country in the world, coal-fired power generation still dominates China's power supply structure. In order to further reduce the unit energy consumption and environmental pollution of thermal power generation, China has newly launched a number of high-efficiency energy-saving and 600MW supercritical thermal power unit projects in recent years. However, the 600MW supercritical thermal power unit project currently under construction and put into operation in China is the spiral water ring wall of the boiler water wall heating surface. The vertical pipe water-cooled wall supercritical boiler technology, which is increasingly favored by users and has low resistance and easy installation and installation, is still blank in China.
With its mature technology in the field of 600MW subcritical boilers, Harbin has cooperated with Xi'an Jiaotong University to independently develop 600MW supercritical vertical pipe water wall boiler technology according to the design, manufacturing and operation experience of domestic supercritical boilers. The core technology of supercritical boilers has already possessed the design and manufacturing capabilities of this product, which can meet the market demand for this product and open up a broad space for enterprise development.

Wood lathes can be used to create functional furniture components, beautiful decorative wood projects such as candlesticks and bowls, or even toys such as tops and yo yos. These machines range in size from hobby models that fit on a work bench to large industrial-sized machines weighing hundreds of pounds, but they all share some basic elements. Here are some instructions for using these unique machines. For those in the machining and turning crafts, it`s common knowledge that the Industrial Revolution had a significant impact on the evolution of the lathe and additional machine tools. As humans began developing tools and technology, honing new skills, and began more efficient ways of production, different power sources started to become standard. Motors now required electricity, meaning the conventional way of operating machine tools by human touch was being phased out as more and more machinists were [turning" to automation. But before automation and metalworking became regular practices in the machining world, there was woodturning and thus, wood lathes.
