Since November, the Hulun Buir City, Inner Mongolia Special Equipment Inspection conducted inspection operation in the southern region of the Greater Xing'an Mountains in the boiler, the number of test boiler total of 44 units.
The inspection work will strictly follow the "Boiler Safety Technology Supervision" and "boiler regular inspection rules" to. For affiliated found during inspection instruments and safety accessories not check and did not check after the expiration of other safety hazards at the scene told directly using the unit, and issued a "special equipment inspection and opinions notice" to avoid a security incident in the boiler during operation .
We found that there are a lot of people on both boilers and steam generator taper roller bearing lm12748 12710s could not tell, and take a lot of detours at the time of counsel and buying. Through the above comparison of the differences we boiler and steam generator, it can first in accordance with the needs of their business, and then determine the selection Which devices.
Rated evaporation gas steam boiler rated evaporation to choose the size of the boiler steam boiler is a proper noun, which is the power of steam boilers. Calculated: (ton unit) the general power steam generator taper roller bearing lm12748 12710s are rated by evaporation. Rated evaporation is a boiler to heat water per hour becomes steam production. This is the main argument when we need to consider the selection of steam boilers. How to choose the right Rated evaporation it? Generally, we first calculate the own use of steam per hour required, if the hotel laundry room and hospital disinfection equipment, you can see through the steam parameters parameters to calculate laundry facilities needed for every hour; if it is the plant process steam then it can be calculated per hour of steam required by the process. After calculating their required amount of steam we can choose the boiler, and generally we need to select the rated evaporation than we calculate the steam boiler with 20% of the amount. Because there may be some cases in the actual use of the process to increase the amount of steam, or steam boiler does not reach its ideal operating conditions. Here should be noted that, in accordance with our steam boilers are marked on the boiler rated pressure to calculate the rated evaporation, and some foreign steam boiler is zero pressure steam production to the subject. Such as poly rated pressure force is 1.0Mpa steam boiler, the steam temperature is 184 deg.] C to produce, while the zero pressure steam production refers to the production of steam output of 100 deg.] C, to the middle of the big difference.
10.Steam is super heated to a high temperature and pressure in the primary super-heaters and then moves to the secondary super-heaters.
11.In the secondary super-heaters steam meets the very hot gases exiting the top of the boiler. The steam is heated to its final temperature and pressure before leaving the boiler as main steam. The main steam is sent to the high pressure steam turbine. The steam turbines drive a generator which produces electricity.
12.Steam exiting the high pressure steam turbine is called cold reheat. It is reheated in the re-heater and sent back to the second steam turbine. By the time the flue gas exits the boiler most of the energy in the coal will be transferred to the water in the boiler. The hot gases are cleaned up before they are sent to a stack. Feed-water is generally supplied by condensed steam from the low pressure steam turbine. Large amounts of cooling water are used to condense this steam into liquid water in the condenser.
