boiler system of 250 mw tps

Gas heating boiler system of 250 mw tps operation and management system to resolve the gas heating boiler heating system will be relatively complex, requiring a strict management system to ensure safe heating boiler running smoothly in this process need to pay attention to the following points: 1. The quality of boiler water must to go through rigorous testing, sub-standard water to be softened to avoid scaling, corrosion and other boiler components after use, affecting the thermal efficiency and operational safety late boiler. 2. boiler and its auxiliary system is operating normally, if abnormal timely feedback process. 3. Ensure the indicators boiler water systems, safety accessories and other normal and flexible. 4. boiler operator rigorous specialized training and work and strict management system, be sure to do, patrol officers and operators keep alert, can not be insensitive. Inspection time designated times to be once per hour. Period of time to carry out maintenance and repair timely 5. boiler shutdown. To ensure that the boiler inside and outside the normal indicators, the device remains clean and orderly. 6. In addition, during each inspection of boiler operation, inspection, etc., must do text and data records to ensure that when the transfer of work to be a clear understanding of boiler operating conditions between the transfer of personnel. Of course, the normal norms of these will be far more complex, these are the general direction in which, in any case, to ensure safe operation, the safety of gas heating boiler, while maximizing operating results play a boiler, strict implementation of the operation and management system It is a necessary operation.

Can be found in the above comparison, operating costs 10 tons of coal-fired boiler system of 250 mw tpss and gas boilers difference of 2 times (2.1-2.4 times), if only consider the price, the cost of natural gas feedstock is indeed expensive.

Boiler is a specific type of boiler system of 250 mw tps, but also a website product and key words, therefore, it is necessary to carry out a comprehensive understanding and understanding, because only in this way, can the proper operation of the boiler and obtain a good use effect, and then, It has good economic benefits in its economic performance. 1. How to ensure the safety of boiler use? To ensure the safety of boiler use, we can proceed from the following aspects: (1) strictly control the operating pressure of the boiler, do not allow it to exceed the prescribed range, once there is a tendency to exceed the prescribed upper limit value, Immediate measures should be taken to address and eliminate. (2) strict control Good boiler temperature, because if the boiler temperature is too high, it will lead to the failure of the furnace tube, resulting in various problems, and affect the normal operation of the boiler. (3) regular boiler maintenance should be carried out. In order to ensure its service performance and service life, (4) in the boiler self-designed design and structure, we should also avoid problems, can not have design defects. Is the boiler oven simple? Boiler oven, from a professional point of view, the operation is not difficult and complex. The temperature of furnace water should be kept in the range of 70 ℃-80 ℃, and the furnace temperature should be raised. It should be carried out slowly to ensure the uniform expansion of all parts of the boiler. 3. Is there a requirement for the upper limit of the boiler's temperature? In boilers, at present, there is no mandatory requirement for the upper limit of temperature, but according to practical operating experience, do not exceed 300 degrees, because if the temperature exceeds 300 degrees, The boiler combustion will be unstable and prone to carbon deposition. In the temperature difference, it is about 10 degrees is better. 4. What is the pressure in the boiler? In this kind of boiler, there are two kinds of pressure, operation pressure and saturated steam pressure, but this is under the condition that the medium of boiler is liquid phase circulation. And, when When the operating pressure of the boiler is low and the temperature is 350 ℃, the operating pressure of the boiler is 0.0588 MPA and the saturated steam pressure of water is 16.43 MPA.
