Inspection and use preparation of oil and gas boiler. Inspection of the furnace and flue, and the soot and sundries in the furnace and flue shall be removed. Shaanxi Horizontal fuel gas steam generator Check the boiler accessories to see if they are in good condition; Whether the cock can rotate easily; Whether the instruments and control devices are in good condition and clean. After inspection, the pressure gauge cock shall be in working condition. Check the automatic control system. Check the auxiliary equipment of oil and gas boiler. Check the combustion equipment to see if the combustion equipment is in good condition; For mechanical transmission system, coal handling system and ballast system, the test steering is normal; The spring of the gearbox shall be properly compressed and lubricated; The indication of coal door gauge is correct. vertical Horizontal fuel gas steam generator factory The eagle iron is neat and complete, and the ballast plate is complete. Check the heating surface and ensure that the equipment coupling is firmly connected; V-belt is loose properly; The lubricating oil is in good condition; The cooling water is smooth. After passing the test, install the protective cover, test run separately, and pay attention to the current during idling.

Enterprises that rely on coal for power generation are both traditional power enterprises and highly polluting enterprises. The industrial waste gas discharged by coal power generation enterprises has seriously polluted our living environment. Shaanxi Horizontal fuel gas steam generator As a result, the country has become more and more strict in the control of this industry, and how to use waste heat recycling power generation has become a topic of concern for many enterprises. Waste heat boiler can meet this demand of enterprises, so its application in coal mine power generation enterprises is more and more. vertical Horizontal fuel gas steam generator factory Installing a waste heat recovery boiler on the exhaust pipe of the coal mine gas generator set, using the waste heat discharged by the coal mine gas generator set to generate steam for power generation, can not only turn waste into treasure to realize the secondary utilization of energy, achieve the goal of combining coal mine gas control with energy conservation and emission reduction, but also reduce environmental pollution, kill two birds with one stone.

When using stainless steel storage tank, cracks appear on the head. If it is not handled in time, it will be dangerous, and how to handle this situation will be explained. Shaanxi Horizontal fuel gas steam generator Firstly, the cracks in the stainless steel tank can were removed by polishing. After grinding, pits that do not need repair welding and do not affect the grading shall be formed within the allowable range. Otherwise, repair welding shall be carried out. The position of surface crack defect shall be determined by surface penetration defect detection, and the welding repair shall be completed. The horizontal gas tank shall be repaired, and the weld and surrounding materials shall be repaired. After that, argon tungsten arc welding shall be used for repair welding. vertical Horizontal fuel gas steam generator factory Tungsten argon arc welding shall be adopted for welding repair. It is suitable for back welding or skip welding, small size multi-layer and multi pass non rotating welding to avoid overheating of the weld. Water cooling measures are adopted. The defects of stainless steel storage tanks shall be removed by grinding with angular grinding wheel with conical grinding rod. Note that the abrasive grains of the grinding wheel should be perpendicular to the crack length. If the defect is deep, crack stop holes shall be drilled at both ends of the defect to prevent the crack from expanding with the grinding process. According to the inspection, in the stainless steel storage tank with primary side inspection, there are cracks at the head welds, and these defective welds have different edge bite degrees. Do not panic when the stainless steel tank can has cracks. The oil tank works. The above measures can be taken to solve this problem.

The waste heat boiler is composed of drum, movable smoke hood, feeding pipe groove, oxygen lance mouth, furnace mouth section flue, inclined section 1 flue, inclined section 2 flue, last section 1 flue, last section 2 flue, nitrogen sealing device and nitrogen sealing plug, manhole, micro differential pressure tapping device, flue support and hanger. Shaanxi Horizontal fuel gas steam generator Unlike conventional boilers, waste heat boilers do not produce combustion process and do not have combustion related equipment. Essentially, they are just gas water/steam heat exchangers. The waste heat boiler is divided into six circulation loops. Each circulation loop is composed of downcomer and riser. The feed water of each section of flue is introduced from the drum through downcomer to the lower header of each flue, and then enters into each heating surface. The water passes through the heating surface and generates steam into the header, and then is introduced into the drum through the riser. vertical Horizontal fuel gas steam generator factory The needle tube waste heat recovery device is a special high-efficient energy-saving product specially designed for waste heat recovery of flue gas. The heat recovery boiler uses needle shaped tubes to strengthen the heat elements to expand the heating surface. The heating surface on the water pipe smoke side can be greatly increased. At the same time, the smoke will form strong turbulence when passing through the needle shaped tube surface, which will improve the heat transfer efficiency and reduce the soot accumulation.

As a pressure vessel, waste heat boiler shall be used reasonably and managed scientifically in the process of use to avoid safety accidents caused by improper use and management. The quality of water is one of the important factors affecting the service life and safe operation of waste heat boiler. The quality of water added into the boiler directly affects the normal operation of waste heat boiler. Shaanxi Horizontal fuel gas steam generator The normal delivery of water is the lifeblood of normal boiler use. If the boiler is short of water, it is bound to cause major safety accidents and fatal damage to the boiler. Therefore, it is necessary to ensure continuous and stable water transmission during boiler operation. vertical Horizontal fuel gas steam generator factory Regardless of the tonnage of the waste heat boiler, the lower configuration of the boiler electric control shall ensure the continuous operation of the boiler water pump, and the water supply pipeline shall be equipped with a water supply regulating valve with good regulation characteristics to control the water supply flow according to the level of the boiler. In addition, in order to ensure that the normal delivery of water will not be affected by the pump failure, a standby pump should be ensured.
