How to prevent running back pass secondary combustion 1, 30% of the rated condensation boiler to deal with the amount of purge air before boiler ignition; the boiler must be 30% of rated air flow purge less than 5 minutes after the boiler fire, or allowed to boiler re-ignition. 2, fine-tuning the boiler and combustion systems pulverizing system operating conditions, to prevent incomplete combustion of oil and coal accumulating on the tail heating surface or flue. 3, boiler burning oil, adjust the proper air flow, fuel flow, confirming good gun oil spray, burning completely. If you find a bad oil spray gun should be discontinued immediately, and clean up. 4, when the oil application group administered powder, cast powder should be confirmed before the oil burner ignition good, or allowed to cast powder. 5, the oil powder boiler during cofiring, and check the fuel oil gun system of fire reinforcement. 6, normal operation, operation personnel in monitoring the economizer, an air preheater flue tobacco in different conditions of temperature, abnormal, should be checked to detect a fire-place. 7, air preheater sootblowing steam system normally put into operation, the soot-blowing pressure and temperature in a predetermined range. When the unit load or less prolonged 300MW kerosene mixed combustion, air preheater sootblowing steam to be continuous. 8, the air preheater into a reliable fire alarm device. 9, an air preheater inlet and outlet fume / air damper, and should be able to put an electric shutter can be open, closed tight. 10, if found preheater stall, should be put into operation again immediately, if not turn back, they should be isolated.
How to improve the thermal efficiency of gas steam condensation boiler steam boiler to improve the thermal efficiency of gas is a problem many users are taken, I believe this issue is the direction of each used in the production of various types of gas steam boiler manufacturers have been in the study. Many users at the time of the gas-steam oven operates, often in the actual production process, we found some new problems, but all the problems, the most vexing is the high temperature exhaust gas steam boilers, thermal efficiency than low phenomenon that a serious impact on our work, then how should we do to improve the thermal efficiency of it? need to know this is the best way to meet the low-temperature properties of gas and steam comes as synthetic gas steam. However, the vast majority of synthetic gas and steam biphenyls, benzene derivatives of both components of the complex, or a vapor of volatiles has strong carcinogenicity, it is strongly recommended that the client select the type of mineral oil vapor product gas. Second, gas and steam products to meet the low temperature performance process, but also have a relatively high flash point required. In general, gas steam engineers suggest, low temperature gas steam flash point not lower than the opening 200 ℃. After a professional manufacturer of continuous research and improvement of its equipment, in order to improve its thermal efficiency was found to be increased tail gas steam boiler heating surface of, say, air preheater and economizer. But when organic heat carrier furnace return temperature is high, you can not set the economizer, air preheater can only be set to alleviate the situation. So if no gas steam boiler and other heating systems for low temperature heat exchanger, then the only way to improve the energy efficiency is adding air preheater. After adding air preheater can be a corresponding increase in gas flow rate of steam, gas steam boiler in order to ensure safe, reliable and stable work, the thermal efficiency of gas-steam boiler plant will be a corresponding with the increase.
Inside the Fangkuai condensation boiler plant, there is a special corrugated furnace bladder production line, which can be processed according to the computer setting mode. At the same time, this is also a unique processing technology of Fangkuai Boiler. The cost of natural gas fuel alone exceeds 5 million yuan per year. The corrugated furnace liner fired by this production line can not only increase the heating surface of the boiler, but also alleviate the damage caused by the thermal expansion and contraction to the combustion chamber, and greatly extend the service life of the boiler.
The price of 1 ton of diesel steam condensation boiler how much? Diesel fuel boilers name suggests, is a diesel fuel as a boiler, in general belongs to a diesel boiler is oil-fired boiler series, you can also burn heavy oil, waste oil and other oils. Diesel boiler works mainly by the diesel burner (atomized) is injected into the combustion liner, into the flue gas back to the combustion chamber around the lower part of the smoke tube, forward to the front smoke box, smoke tube folding the upper, front to back It flows into the smoke box, through the chimney into the atmosphere. The price of diesel boilers have a lot, but the difference between what it? Here Henan party fast as a veteran enterprise for everyone under the doubts, the main part of the boiler refers to diesel burner, because they want to go with burner according to the viscosity and calorific value of burning oil, so the price difference is mainly in this, Henan side uses fast Italian imported burner compared to other conventional burner following advantages: 1, by volume petite we know the burner mounted in the side wall and the center distance ships diesel burner installation is not less than 1 1.2m ~, smaller volume so that the installation easier and faster. 2, stable performance increase wind speed exit back to improve combustion efficiency, good burner does not need to apply debugging, and some common die. 3, the combustion load bearing capability can bear the name suggests is a heavy load without damaging the load, but not always.Free Chat
