Manual Coal Steam Boiler Features
1.The boiler has big drum and have big enough space for water. Compared with the SZL series, the DZL boiler is more adaptable to poor water quality. Moreover , when the boiler scaled, it is convenient for maintenance.
2. Adopting convex tube plate, prevent tube plate cracking and simplify the structure of canceling the tension bar.
3. The Wing-shape flue arrangement, the flue gas is three pass, reduce the smoke temperature of high temperature area tube plate, thereby preventing the cracking of tube plate and Boiler tube explosion.
4. Adopting threaded smoke-tube technology, strengthen heat transfer, reduce the number of pipes and the size of boiler shell; reduce the thermal stress at the end of the pipe, and prevent cracking of the tube plate. At the same time, due to the self-cleaning ability of the flue gas in the threaded pipe, avoid the accumulation of dust in the tube.
5. The boiler has sufficient output, fast speed heating and high thermal efficiency.

The largest of these projects is Shanghai Yachuang Investment and Development Co., Ltd.'s investment in Chengdu Hi-tech Zone to build an auto parts distribution center. Before the signing ceremony, Ben Wang reporter interviewed Mr. Gao, the Shanghai contracting representative. He said that the investment in Chengdu was mainly due to the large amount of room for development in Chengdu's logistics and auto parts. He also invested a lot in “hardwareâ€. It is hoped that through the cooperation of the two sides, Sichuan will bring more advanced logistics management experience from the coast. Become a leading auto parts base in the southwest region. He told reporters that he is very satisfied with the overall investment environment in Chengdu. “The efficiency of the work here is high, the overall hardware environment is good, and infrastructure construction can keep up.†Source: Sichuan News
