Incorrect operation of steam high medium low pressure boilers and leaking how to do? Most of the steam boiler with a certain pressure, high-temperature steam can be output at the same time heating the water, belong to special pressure equipment clearly defined our country, and the implementation of specific practices. Whether the operation meets the requirements will directly affect the life of the boiler, which is why some steam boiler service life is very short, but others can achieve long service life. When incorrect operation of steam boilers and leaking, do not panic, we can save. First, a cause, there is no oxygen to the boiler feed water of high oxygen content resulting in oxygen evolution boiler operation cause corrosion in the gas accumulation space. 2, improper daily operation, a shutdown did not close the valve when the steam valve or the main pipe, air into the furnace, so that when using the boost again, did not exclude the entry of oxygen, so that in a hot and humid environment caused by oxygen long-term corrosion perforation of the smoke pipe. Second, the standard operation 1, boiler feed water in accordance with standard GB1576-2008 oxygen, reduce the oxygen content. 2, during shutdown, a shutdown while the boiler is in the normal high water level and normal pressure, and then close the inlet valve and the main valve, to prevent intrusion of outside air oven. 3, when the furnace is first started slightly open the main exhaust valve until the pressure reaches 0.1-0.15MPa closing the main valve to eliminate air furnace, and then open the main valve when the air supply to the rated pressure. 4, strengthen valve maintenance, maintaining rigor.

A high-pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal. In the later years of steam, boiler pressures were typically 200 to 250 psi (1.38 to 1.72 MPa).High-pressure locomotives can be considered to start at 350 psi (2.41 MPa), when special construction techniques become necessary, but some had boilers thatOnline chat
The key difference between low and high pressure systems is that low pressure systems are regions in the atmosphere where the air is rising, while high pressure systems are regions in the atmosphere where the air is descending.. The word pressure system is a common term in meteorological reports, and in the news and often indicates that something is out of place.Online chat
