Treatment of four-tube Fault in small-sized Oil-fired BoilerSmall oil-fired boiler four-tube is the boiler's water wall, economizer, superheater, reheater. The reason for the high failure rate of the four tubes is that the external working environment is bad, and it needs to withstand the radiation of high temperature flue gas and particles, corrosion, convective shock, local heat irregularity, and the interior contains high temperature and high pressure liquid, gas or liquid gas mixture. Causes such as external wear, poor material, poor welding, corrosion of flue gas, fracture caused by external force or stress and so on, may cause four pipes; leakage accidents occur. The recommended solution is to make use of acoustic spectrum analysis and other techniques to monitor the leakage of boiler four tubes in real-time on-line, to detect its slight leakage in the early stage of failure and to alert it in time, so that personnel can carry out important on-the-spot inspection and safety. Arrange reasonable maintenance, thus avoiding the passive accident maintenance. The widely used method of monitoring leakage is the observation and monitoring of operators in the process of inspection, and the analysis and judgment of the change of steam flow rate, pressure, temperature and water supply by using the parameters such as steam flow rate, pressure, temperature and water supply. The common disadvantage of these methods is that the real-time performance is poor and there is a great lag, and the delay time depends on the intensity of people's attention time, so the method to improve the real-time performance must increase the intensity of personnel's work. However, if the pipeline characteristics of small oil-fired boiler are not found and dealt with in time, if the internal pressure is leaked, it will lead to more serious impact and treatment. Damage, resulting in the difficulty and workload of maintenance, thereby increasing maintenance costs and downtime. This requires automatic monitoring and protection system-based, manual-assisted three-dimensional security management.

Why there will be gas-fired boiler drum wall temperature difference between the upper and lower walls of the upper and lower gas boiler drum boiler temperature difference will cause some damage to the wall of the drum by the compressive stress, tensile stress at the wall by the stress reaches a certain extent gas boiler drum damage occurs even crack. Why would the temperature difference between such a phenomenon? That is because the initial ignition gas boiler drum upper and lower walls will have a certain degree of temperature difference, it is because the initial heating gas boiler, a low metal vapor drum wall temperature, the wall surface of the steam condensation occurs on heat drum, the drum wall in contact with water in contact with the water also occur on the lower wall surface of the heat, but due to the exothermic coefficient of water vapor condensation than the larger, upper drum wall endotherm, therefore the gas temperature of the boiler drum arm is higher than that under the wall faster. This requires us to run gas boiler run time to pay attention to some issues, so as to avoid damage to the gas boiler, ensure the normal operation of the gas boiler.

With many years of research experience in the fast side of the boiler tube sheet treatment before returning to cracking combustion chamber developed a set of specific measures to reduce the risk of cracking. 1, with a temperature resistance, very good heat insulation effect pull the front edge of the ceramic tube weld shield back to the combustion chamber of the tube plate, the construction is not only simple, but also the quality is guaranteed. 2, the laying of multiple smoke tube inlet refractory cement, smoke exposure and reduce impact erosion. 3, smoke tube extending pipe length is set to 3 mm long, reducing the flue gas scour.

Shunde main business of special sea oil production and processing, etc., in the course of special oil refining, a large amount of steam required for oil and gas extraction, distillation and extraction technology and other aspects, therefore, the boiler is supplied special sea oil processing technology company Shunde indispensable less equipment. As environmental policy progresses, the chemical industry as more polluting industries are highly valued the various departments of quality supervision, sea Shunde companies to follow the development of the State Environmental Protection pace, choose clean the boiler industry-leading fast Boiler cooperation with the parties by quickly assess the specific needs on-site estimates and sea Shunde, to provide a SZS series of 25 tons of steam water tube lp steam boilers auckland (SZS25-2.0-YQ).
