Shall manufacture, import, sale and use do not meet environmental standards or requirements of the boiler.

41: partial restriction sulfur, high ash coal mining, mining prohibition radioactive and arsenic and other toxic substances than standard coal. New coal mines must simultaneously supporting the construction of coal washing facilities. Have been built coal mines, it should be in accordance with national requirements, supporting the deadline for the completion of the coal washing facilities.

Prohibit the import, sale and burning of coal does not meet quality standards, to encourage high-quality coal burning.

Prohibit the import, sale and burning does not meet the quality standards of petroleum coke.

Because of the different equipment and external temperature, when the hot water flow, the internal wall of the steam drum will approach the water, the drum temperature will increase. But the temperature of external wall will increase more slowly than the internal one. The higher the temperature difference is, the strong the thermal stress will be. the higher temperature and faster feeding speed of the water will cause larger temperature difference which will result deformation and fissure. Otherwise, it may also cause the uneven inflation of water wall. Therefore, when feeding water to the ship steam fire tube boiler, it is necessary to set a limit to the water temperature and the feeding speed.
