Zhao Zhuang, general manager of Dongfeng Chaoyang Diesel Engine Co., Ltd., a pillar industry in Chaoyang City, said in an interview: “When the world economy hits a low point, sales of our products have hit new highs. Thanks to the country’s macro adjustments—expanding domestic demand, ensuring growth, promoting stability, and vigorously strengthening infrastructure construction, it has effectively boosted the 'heating up' of transportation and its manufacturing industries. Forward-looking and effective management is particularly important, and occupying this strategic high ground, companies will always be invincible.The government and all sectors concerned with supporting the survival and development of enterprises should actively guide enterprises to clearly understand the extreme importance of forward-looking. Sex, abandon the 'push grinding type' guiding ideology and work methods, so that companies enter the track of sustainable development." In the past few years, Dongfeng Chaoyang Diesel Engine Co., Ltd. has been learning modestly but does not rely on foreign advanced diesel engine production technology. It has insisted on independent innovation and has accumulated continuously; it has developed jointly and formed features; it has thoroughly "digested" and incrementally promoted scientific methods. Step by step, and always keep in line with international standards, so they produce diesel engine high quality, cheap, first-class service, very suitable for consumers' appetite, will certainly occupy a larger share of the domestic and international markets. When the financial crisis hits, it is not surprising that they have risen against the trend. For example, in the domestic market's production and sales, they adapt to the traditional Chinese cultural concepts, overcome the drawbacks of "imperfection of water and soil," and expand services to make products more humane and caring for the people to truly taste the "sweetness" of economical and durable sales performance. All the way up. The company is the first high-speed automotive diesel engine production base in China, a large-scale professional diesel engine enterprise integrating product development, production, and sales. The "CY" brand diesel engine produced by Chaochao has 102, 3 liters, D, The four major series of gas products, the full range of products have reached the Euro III standard, and have a development platform for Euro IV emission standards. "CY" brand diesel engine has the characteristics of small size, high power, low noise, good start-up performance and high reliability, and is regarded as the first brand of China's light-duty diesel engine. At present, this product is used by more than 100 affiliated companies such as Dongfeng Motor Corporation, and has a social possession of more than 1.6 million units. It is exported to more than 40 countries and regions on a stand-alone basis or on-board, with an annual export volume of over 10,000 units, and an overseas market holding of nearly 5 units. Million Taiwan, ranking the domestic leader in the same industry.
The first type is the bare pipe water wall. This is the simplest structure of the water wall. The advantage is that ordinary seamless steel pipes can be used, and it is more convenient to replace the water wall pipe. The disadvantage is that the temperature of the furnace wall is still high, and heavy refractory bricks are required. The steel frame of the corresponding boiler should be strengthened. , The air leakage of the furnace wall is relatively large. Old-fashioned high-pressure boilers and medium and small boilers are used more frequently.
The second tupe is the membrane water wall. The membrane water wall is welded by seamless steel tubes with fins. The Water Wall Tubes are connected by fins to make the water wall into a whole. This kind of water wall is called a membrane water wall. Its function is to strengthen the heat transfer of the water wall and greatly reduce the temperature of the furnace wall. The furnace wall does not need refractory bricks, but only requires thermal insulation materials. Compared with the conventional heavy furnace wall, the weight can be reduced by 60% ~ 70%, the furnace wall heat storage is reduced by 80%, the start and stop time is shortened, and the fuel consumption is reduced. The load of the furnace steel frame is greatly reduced, saving refractory materials and steel.
The third type is the pierced pipe water wall. The barbed pipe water wall pipe is made by welding many grab nails with a length of 20 to 26 mm and a diameter of 6 to 12 mm on the water wall pipe. It is mainly used to lay the gas belt. Generally, for boilers that burn fuel with low calorific value and low volatile content, in order to stabilize the fire, pierced pipe water walls are often used for laying the fire protection belt.

The boiler water wall is the main radiation heat surface, arranged inside the boiler chamber and proceeds the heat exchange directly with the high temperature flame. The convection tubes are the convection heat surface of the boiler, arranged between the boiler chamber outlet and the end heat surface and proceed the heat exchange directly with the high temperature fume. The water wall and convection tubes are the main heat surface of the boiler, the tubes diameter for both generally usedΦ 51-60mm boiler steel tubes, also as the request.
