For different working pressures characteristics of fire tube boilers, to have a separate steam pipes and water pipes, respectively. If when a combination of the main steam pipe, the steam pipe to be fitted with high pressure apparatus and the automatic depressurization safety device that prevents the low-pressure side of the overpressure. When the water pressure does not exceed 20% of the maximum pressure, the system can feed water to the boiler feed water from the total.
Inside the Fangkuai characteristics of fire tube 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.
Textile companies need steam for drying, printing, and shaping, and the quality of steam is critical to the quality of the garment. The choice of steam characteristics of fire tube boilers requires more care.
Chemical plant characteristics of fire tube boiler drum bottom drum of which the bottom of the chemical plant boiler drum drum of which the bottom of the boiler drum drum of chemical plants What? From the test results and the situation of the boiler water treatment point of view, I believe, result in the bottom of the drum drum kit are the following two reasons. 1, the direct cause quick bottom boiler drum, directly by irradiation of the high temperature flame, and also by the erosion of the high temperature flue gas, when the bottom of the boiler water-side time scaling, since the scale of the thermal resistance of the metal material 40 to 100 times, poor thermal conductivity, so that heat can not be timely cooled furnace wall, resulting in ultra-high wall temperature, so that the strength of the metal furnace wall decreases, the time when the boiler pressure exceeds the yield limit of the furnace wall, the furnace wall may occur plastic deformation of the metal , the performance of the macro as a drum kit. 2, indirect causes of 2.1, when the structural defects of DZL DZL boiler furnace shorter boilers, combustion anthracite, anthracite because of high heat value, high flame temperature, lower furnace combustion unfavorable, if water is not in place, close to the flame easier generated in the boiler tube expansion. 2.2, boiler operation and management is not in place, managers thought the boiler is not ideal to use water treatment units do not pay attention, careless, boiler operator skill level is low, sense of duty, may cause boiler blowdown unscientific or not timely, water treatment poor, resulting in smoke tube boiler drum water wall tubes and other major health large scale pressure element junction. Now the half of the boiler water quality more representative test report, wherein the pH of the feed water (25 ℃) between 6.5 to 6.9, lower than the standard value (7.0 to 10.0); in hardness 1.0mmol / L ~ 2.0mmol / between L.
