How to prevent running back pass secondary combustion 1, 30% of the rated 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.

Steam boiler is too many forms, take an ordinary fast-packed 4-ton steam boiler. Water is heated into steam in the drum and heat is emitted by fire in the furnace, which is the principle of the steam boiler. Say the boiler first the pot. The boiler is a drum boiler with water cooling. Two return pyrotechnic tubes are arranged in the left and right parts of the drum, and the front cigarette box in the front part of the drum is turned back. Between the drum and the bottom box, there is a drop tube and a water-cooled tube, forming the frame of the combustion chamber. There is a steam separator on the top of the drum to reduce the water produced by steam. The heating surface of the boiler is the lower part of the drum, water-cooled pipe and pyrotechnic pipe. The combustion part consists of a chain grate and a drive device, Add the boiler frame on the grate of the composition of the combustion chamber composition. Surrounded by refractories. Coal from coal hopper, there are coal gate to control the thickness of coal seam while sealing the front of the air. The lower part of the combustion chamber is the place where the blast enters, and this kind of boiler has great resistance and needs forced blast. Cinder, discharged from the back of the grate through hawk iron and sent out of the furnace by the slag extractor. From the back of the boiler, the flue gas goes forward from the first return pipe of the boiler, the second return pipe returns to the rear part of the boiler, and then goes into the dust collector to separate the ash, and then through the draught fan, it is discharged from the chimney. The induced draft fan is not only the exhaust gas, but also necessary for the negative pressure operation of the boiler. Steam boiler is pressure capacity Device, safety device is necessary. Essential water level gauges, pressure gauges, safety valves, thermometers, electric pumps that can replenish water under pressure, and steam pumps that can also be used in the event of power outages. Boiler water must be softened and water treatment equipment.

Steam boiler room with open water What are the benefits? And today we introduce the open water with steam boiler room What are the benefits? This problem was first let me introduce the characteristics of the Company's production of steam boilers, steam boilers are divided into: coal-fired steam boiler, oil, gas and electric heating steam boiler steam boiler. Because water boilers of this capacity is less than 30 liters, so this boiler without inspection and acceptance, the boiler model from 0.3 to 2 tons, coal-fired steam boiler in the steam can be 3 minutes, the fuel gas steam boiler within 3 minutes of pressure can reach four. Boiler fool-operation, automation Chengdu is very high, the operation is very convenient, each boiler before the factory to go through checks at each level, are installed in the company, then shipped to the point of use as long as it is connected to the washing equipment the company has a test product if the user to visit the company allows users hands-on experience can be normal use. These are open today introduced washing room with steam boilers What are the benefits? Content, we are hoping to help those who are ready to open the washing room.

The party hot water boiler output fast enough to provide high efficiency, give us save a lot of fuel costs, and exhaust gas discharged tested in full compliance with environmental regulations on emissions of air pollutants in Henan Province. Fast boiler responsible attitude also left us with a deep impression, overhaul maintenance problems for a number of aspects of boiler operation and post, sent a very professional technical staff and our butt, fireman guide our people, for the quick sale of party, we are also very satisfied. --customer feedback
