According to data from China Drying Network , the average price of thermal coal for the 5,500-calorie kilo-card market in the Bohai Rim region was reported at 628 yuan/ton, up by 1 yuan/ton from a week earlier. Thermal coal prices are weak, and industry experts expect domestic coal demand to continue to slow in the second half of this year.

Judging from the transaction prices of the six ports in the Bohai Rim, out of the 24 varieties, the varieties with the same prices were reduced from 18 in the previous reporting period to 10; the varieties with increased prices increased from 5 in the previous reporting period to 13. Li Xuegang, general manager of Qinhuangdao Coal Trading Market, believes that the current favorable factors and unfavorable factors affecting the supply and demand of thermal coal in the Bohai Rim region are evenly matched. The coal stocks that are still high on the main power companies are under development and present a trend of expansion of thermal power units. Daqin Line The postponement of the fall of overhaul in autumn and the expected decline in the impact of maintenance on transport capacity all constrain the rebound of thermal coal in the market in the region.

Dong Yueying, secretary-general of the China Coal Transportation and Marketing Association, said that due to the sluggish industrial production activity and the overall slowdown in the domestic economy, domestic coal demand is expected to slow down in the second half of this year, and the national electricity consumption in the second half of the year is expected to increase by only 6.8% year-on-year, while crude steel The output will increase by 2% year-on-year. Dong Yueying believes that due to the impact of the domestic economic slowdown, domestic coal demand this year will be the same as last year, or only slightly higher than last year.

Dong Yueying revealed that in July this year, China’s coal production and consumption declined for the first time in the year. According to data from the China Coal Transportation and Marketing Association, China’s coal production in July was 310 million tons, down 1% from the same period of last year, and coal consumption was only 295 million tons, down 2.7% from the same period of last year.

The Seaborne Coal Freight Index (OCFI) issued by the Qinhuangdao Maritime Coal Market shows that on 4 September, the domestic seaborne coal freight rate rebounded slightly from August 28, and the average coal freight rate of the 4-5 million tons ship on the Qinhuangdao to Shanghai route rose. 0.2 yuan/ton to 33.6 yuan/ton; the average coal freight rate of 50,000-60,000 tons of ships on the Qinhuangdao-Guangzhou route rose by 1.6 yuan/ton to 40.9 yuan/ton; the average coal shipments from 2-3 million tons on Qinhuangdao-Zhangjiagang route were shipped Prices rose by 2.2 yuan/ton to 43.1 yuan/ton.

Pneumatic Valve

Pneumatic ball valve is a ball valve equipped with a pneumatic actuator. The execution speed of the pneumatic actuator is relatively fast. The fastest switching speed is 0.05 seconds / time, so it is usually also called pneumatic quick cut-off ball valve. Pneumatic ball valve is usually equipped with various accessories, such as solenoid valve, air source treatment triplet, limit switch, positioner, control box, etc., to realize local control and remote centralized control. The valve can be controlled in the control room without running to the site or high altitude and dangerous areas for manual control, which saves human resources, time and safety to a great extent.

The pneumatic ball valve can be closed tightly only by using the pneumatic actuator to rotate 90 degrees with the air source and a small rotating torque. The completely equal inner cavity of the valve body provides a very small resistance and straight flow channel for the medium. It is generally considered that the ball valve is most suitable for direct opening and closing. The main feature of the ball valve is its compact structure and easy operation and maintenance. It is suitable for general working media such as water, solvent, acid and natural gas, as well as media with poor working conditions, such as oxygen, hydrogen peroxide, methane and ethylene. The ball valve body can be integral or combined.

Pneumatic butterfly valve is composed of pneumatic actuator and butterfly valve. Pneumatic butterfly valve is a pneumatic valve that uses the circular butterfly plate rotating with the valve stem as the opening and closing property to realize the opening and closing action. It is mainly used as a block valve. It can also be designed to have the function of regulation or section valve and regulation. Butterfly valve is more and more used in low-pressure large and medium-sized pipelines. Classification of pneumatic butterfly valve: stainless steel pneumatic butterfly valve, hard seal pneumatic butterfly valve, soft seal pneumatic butterfly valve and carbon steel pneumatic butterfly valve. The main advantages of pneumatic butterfly valve are simple structure, small volume, light weight and low cost. The characteristics of pneumatic butterfly valve are particularly remarkable. It is installed in a high-altitude concealed channel, controlled by two position five way solenoid valve, easy to operate and can also adjust the flow medium.
