Fire tube china horizontal high efficient boilers introduction

Gas hot water china horizontal high efficient boiler safe operation of the precautions which the following are a few precautions and accident prone: a convection tube, water wall tube blasting reasons: l, substandard materials; installation does not meet regulatory requirements. The layered wall, does not reach the level of weld quality requirements, and other remnants of the inner tube. Wall causing local overheating and burn; 2, feed water quality does not meet standards. Resulting in scaling the wall structure, affect the heat transfer. And cause the wall temperature of the superheated blasting; 3, due to wear of fly ash. So that the wall thickness reduction; 4, fire shutdown heated too fast or too fast, so that the uneven thermal expansion of the tubes. Causing weld cracking; 5, the boiler load is too high, resulting in uneven burning and the outer tube squib severe coking and other reasons. Preventive measures squib: l, before the installation of the pipe rigorous re-examination, have welding welding process instructions; welding quality to meet the design requirements. After the pipe installation to test the pipeline through the ball, passing rate of 100%. 2, to strengthen the water quality management, a test class and demineralized water to achieve the water quality standards, regular inspection and regular elimination of scale and sewage; 3, water wall tubes and pipes to regularly check the exhaust convection, found deformed or thinned tube to be replaced, keeping in mind that the quality of maintenance, must comply with regulatory requirements; 4, the boiler can not work overload control (predetermined limit), attention furnace combustion process, the combustion to ensure homogeneous, stable; 5, note that the tube coking conditions. To achieve timely clear focus and pay attention to leakage. Second, the hot water boiler explosion: the explosion is very serious accident. Damage to equipment and buildings and heating systems are serious. And often resulting in casualties. Analysis following aspects: 1, design and manufacturing problems; a poorly designed, the uneven distribution of traffic in each circulation circuit. Heat too much deviation, solder angular, square, flat plate structure, the steel does not meet the requirements; good manufacturing and repair process. In particular dismay welding quality cells prone to rupture; 2, boiler overpressure eleven operating pressure exceeds the allowable working pressure. Stress plate (internal pressure) higher than the ultimate strength of the steel sheet caused cracking. The main reason is the failure of a safety valve, pressure gauge malfunction, Station Gauges indicate the error. Operating personnel did not take appropriate measures. Not strong sense of responsibility caused; 3, overheating; burned steel overheating broken, or too thick scale is mainly due to the water pan grease or other debris caused by blockage heating surface; 4, corrosion; inner and outer surfaces being coated plates severe corrosion of the steel sheet thickness reduction, the steel sheet insufficient strength caused by rupture; for the above reasons. Summarize a few precautions: l, for manufacturing defects in the design should take the following measures: First, reasonable design. Second, strict related materials, the preparation of three is correct manufacturing processes and process specification cards (including repair), to establish the necessary regulatory Fourth, Fifth, to improve the quality and sense of responsibility of the operators and managers; 2, to prevent overpressure . To ensure safety valve sensitivity and reliability. Regular automatic drainage time. Identify problems in time, also installed on a standard gauge for comparison. And regularly into the metering department inspection; 3, to prevent overheating. You must configure effective water treatment equipment and the establishment of the necessary rules and regulations. So that the boiler is not less furring furring and no accumulation of grease. To check the fouling situation boiler outage. If the scale. You must be promptly cleaned. Scale in order to avoid accretion; 4, preventing internal corrosion. Hot water boiler for larger capacity. The method uses thermal oxygen or chemical oxygen to resolve. In addition. To check the situation of internal and external corrosion. The extent of corrosion repair method such as pile up or Wabu according to (do this before the law, there must be approved by the technical units of the total work program and report to the local supervision departments boiler). To prevent the boiler explosion, regularly carry out the necessary checks on the boiler, at the same time, the boiler management departments should formulate effective measures, operators and managers must strictly enforce minor accidents occurred after the boiler shutdown for maintenance. Tell us about the repair of hot water boiler. 1, when the shutdown may not stop the pump immediately. To be checked after repairs boiler water temperature must be lower than the pump can be stopped when the 50 ℃, at the same time to turn off the water supply valves and heat supply network backwater valve and release the water pot. 2, before entering the boiler, the water must be emptied of all its boiler, sewage emptying all open. Manholes drum, hand holes headers have opened to air convection over time. To enter the interior work, you must pay attention: when someone is working inside. In certain drum outside a supervised. 3, before entering the combustion chamber or flue work. Ventilation must be taken, anti-virus, fire, explosion and other measures. And the total flue chimney flue or other operation of the boiler is connected to the gates are closed tightly. 4, voltage security lighting to use. If the flue inside the drum and more humid. Lighting voltage can not exceed 12V. If dry, the lighting voltage can not exceed 36V. But also have to do to ensure proper safety measures. Do not use open flame lighting.

To protect the economic development of enterprises, production safety running smoothly, according to Qingyang County in Anhui Chizhou municipal government air pollution control requirements, coal-fired china horizontal high efficient boiler inspection pull the plug on a regular basis in October 2018.

Qingyang County Market Supervisory Authority for the county a number of companies were visited research to understand the company's current production operating conditions and problems, start from regulatory functions, for enterprise development to provide quality services, reduce business costs.

Special equipment boiler pressure is high risk, than a regular inspection cycle must immediately stop using, but they are also necessary for the production of business equipment, once the shutdown enterprises will face shutdown. Looking at business owners anxious eyes and counties actively discussing with the city center expert special inspection, and according to regulations, to quickly determine a set of effective programs and promptly inform each enterprise.

Through contact with the surrounding counties and cities to understand the relevant units of the boiler fuel change fees and counties take the initiative and boiler companies approached agreed upon with the use of rehabilitation programs, a significant reduction in transformation costs. Up to now, Qingyang County has completed 12 boiler fuel change work, the cumulative cost of more than 60 million.

4 tons of sewage gas steam china horizontal high efficient boiler regularly introduce 1, regular sewage should be selected in the lower boiler load time, at least once per shift. 2, the sewage must be carried out each time at a high level, a low load. Each discharge point of the discharge time of less than 10 seconds. 3, slowly at first open sewage drain valve near the boiler can be no full impact sound. Then open the two drain valve, can open fully without impact sound, several times off the sewage. Sewage is completed, turn off the two valves, one valve is closed again. 4, when sewage to closely monitor the boiler water level, the water level should be decreased when the pause sewage. 5, regular sewage water amount to no more than 5% of the amount of water. 6, when the quality deterioration of boiler water, boiler water can be concentrated by the discharge portion of the surface water level indicator furnace to improve the quality. 7, sewage principle is: ground row, row less balanced row.
