power plant boilers range

Before a cooperation with the parties, we heard from other companies where fast power plant boilers range brand, saying it was so fast square product quality, use a long time, and after-sales service is also very complete. After the collaboration found that it really is a well-deserved reputation. This three boilers put into use, not only reduces emissions, while meeting the needs of normal heating, fuel input has also been reduced, as we save a lot of operating costs. --customer feedback

Classification steam power plant boilers range: the motive power of water or steam boiler steam cycle divided into: natural circulation boiler, controlled circulation boilers, combined cycle once-through boiler, and the boiler, the boiler and the latter three are collectively referred to as a forced circulation boiler.

How to operate a natural gas power plant boilers range, the preparatory work before starting: 1. Check gas pressure is normal, pipeline valve leaks, valve switch is in place. 2, the test gas reliable alarm system is working properly, the fan can start pressing the test button 3, the system checks whether the normal demineralised water, to ensure that the water softener is operating, the normal water tank. 4, check the boiler, the switching valve is normal decontamination. 5, 6 deaerator normal operation, water softening equipment can operate normally. Demineralized water should meet the standard GB / 576, the normal water level inside the water softener, water pump trouble-free operation. Second, the boot 1, the total power of the switch cabinet, check all parts are normal, whether there is a fault signal. If no signal should take appropriate measures to check or repair, troubleshooting. 2, into the automatic cleaning burner ignition, partial load, full load operating state. 3, when up to a certain pressure, should be regularly sewage once, and check the water level in the furnace. Third, the operation of the inspections: 1, the boiler power is turned on, the monitoring operation of the boiler normal ignition, flame status check, check the operation member without abnormal noise. 2, patrol boiler heating conditions, the size of the converted fire control situation is normal. 3, inspection of gas pressure is normal and stable, the natural gas flow rate is within the normal range, to determine whether the filter is clogged. 4, patrol pump pressure is normal, any abnormal sound. Fourth, the accident shutdown 1, when found in the boiler body to produce abnormal phenomenon, the safety control device failure, emergency disconnect button should move to stop the boiler operation. 2, boiler feed water pump damage, mediation device failure, should move emergency disconnect button to stop the boiler operation. 3, when power problems should take fuels pressing the emergency disconnect button. 4, when a boiler or jeopardize the safety of the phenomenon should take urgent measures to shutdown five temporary power outages Note 1, quickly turn off the main steam valve to prevent dehydration drum 2, turn off the power switch and the gas valve 3, shut down the boiler continuous blowdown valve to prevent the presence of other failures boiler 4, oxygen gas in addition to closing the valve 5, the normal shutdown sequence, checking boiler fuel, gas, water shutdown valve meets the requirements VI Notes 1 insufficient gas, fast scheduling and gas get in touch, ask why clear the accident, and take feasible measures 2, 3 report to the higher authorities and leader, always observe the combustion flame is normal wheat yellow

Theory and hot water power plant boilers range heating area supply and demand and the impact of heating boilers speaking, a ton of hot water boiler can be resolved 10,000 square meters of community heating problem. This is how calculated? First South, the North district heating has been shown in the south different relationship heating Heating relationship northern region as shown main reason for this difference is the impact of climate north and south of the figure below. Generally, 1kg of water for every 1 ℃ to absorb 10 kilocalories thereby obtain 0.7 MW (1 ton) for heat boiler 60 million cards. Therefore, heated from 15 degrees Celsius to 40 degrees Celsius 20 tons of water per hour, how many boilers need? 21000 * (40-15) = 50000kcal (which is an hour to heat the boiler release) Of course, in addition to the temperature difference between north and south, the area of ​​heating hot water boilers factors influence a lot. For example, altitude, local average temperature, building structures, and so the heating effect. In general, the difference between theory and practice is about 2,000 square meters, so the choice of heating hot water boilers, hot water boilers usually choose, slightly larger than the theoretical tonnages. If it is 10,000 square meters of district heating, it is recommended to select 1.4 MW hot water boiler. Reduce water use, not only can reduce operating costs later, and can ensure the operation of the pipeline in late. Depreciation does not affect the boiler heating effect.
