Oil-fired boiler furnace contamination coefficient and the difference between hot and cold spray: 1 tons of fuel oil boiler, its consumption of diesel fuel per hour standard, how much is? Contamination factor within the boiler furnace, how much? And, with regard to this kind of boiler, what other related issues, need to be addressed in a timely manner? Ask these questions, its main purpose is to be completely resolved, so in order to let everyone have a correct understanding, thus, make yourself a lot of benefit. 1.1 tons of fuel boiler, its standard diesel per hour, how much to consume? In addition, how to judge positive and negative pressure fuel boilers? 1 ton oil-fired boiler, its consumption of diesel fuel per hour standard, from a professional point of view, it is 65 kg, if the boiler tonnage of big words, the combustion efficiency can be higher. While the positive and negative pressure fuel boiler judgment, is to look at the direction of the flame spray, is sprayed out positive, a negative pressure is close inwardly.
Boiler Water Shortage Accidents szs water analysis 1, the low water level alarm and interlock protection device is not put into use and failure is the leading cause of the boiler with a flue gas temperature alarm devices and low water level alarm and low water level chain protection. Prior to the incident, said the fireman did not know the level of low water level alarm and interlock protection device has failed. Only because of the economizer outlet flue gas temperature exceeds its limit emerging (designed for 150 ℃), resulting in constantly ringing alarm bells. Fireman turned off the alarm, low water level chain protection device is also close together. Incident, fireman not effectively remind the water, the boiler continues to operate in the case of water, until the drum from collapsing, cracking convection tube squib. Therefore, the low water level alarm and interlock protection device is not put into use and failure is the primary cause. 2, fireman staff is not strong sense of responsibility and lack of experience is a secondary reason for not timely fireman check the health of the boiler, the water level of the false appearance also have not been ascertain. Even if the water level remains normal, but with fireman experience, should determine the average time in Sheung Shui and take appropriate screening measures, so that when the value is less than the fireman experience or did not do to duty. If you regularly observed from the observation hole to the boiler, you can discover the colors and deformation heating surface, and to take action if the boiler severe water shortages. Flue gas temperature alarm occurs first, without making fireman ascertain the cause, any breach of the rules is closed. Moreover, since a long time to eat off-site procedures are also not shift, so this is the responsibility fireman accident. 3, poor management, poor leadership and management is another secondary cause 1) as companies focus only on the production of steam consumption usually very strict, while ignoring safety management, there is no factory fireman personnel safety training. 2) The enterprise security managers no security certificate management, and knowledge of low water level and low water temperature alarm and smoke interlock protection device is not put into use, nor hamper it. 3) flue gas temperature alarm limit adjustment protracted problem, which is not as competent leadership and a great relationship. 4) boiler room management system, check system is not perfect, no preventive maintenance program, so that long-term drain valve leakage state; while the setting of boiler maintenance system, but not implemented, resulting in low water level alarm and interlock protection device is in low water failure state.
Boiler surface quality of the weld quality of the weld surface of the boiler requires requirements: (1) should meet the dimensions of weld design requirements and technical standards, weld and base metal should be a smooth transition, is not less than the height of the weld surface of the base material . (2) the weld heat affected zone and the surface does not allow cracks, pores, craters, and macroscopic defects such as slag. Vertical (3) of the pressure element, and the circumferential weld seam stitching head no undercut, partially undercut the remaining weld depth of not more than 0.5 mm. Sides undercut weld pipe total length of not more than 20% of the circumference of the tube. (4) grinding the weld surface after the elimination of defects or mechanical damage thickness not less than the thickness of the base material. (5) on both sides of the slag and weld spatter must be removed.
