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. Liaoning Gas fired hot blast stove 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 Gas fired hot blast stove 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 long-term use of gas-fired boilers will inevitably lead to problems of one kind or another. However, the working principle of gas-fired boiler is complex, and the price of gas-fired boiler is particularly high, so it is necessary to select high-quality gas-fired boiler manufacturers and companies with good after-sales service. Liaoning Gas fired hot blast stove In addition, what should we do if the gas boiler fails? As the gas-fired boiler involves the construction of gas and lines, the professional installation personnel of the manufacturer must check the installation at home, and the professional personnel shall install it. Improper installation will bring a series of problems for future use. vertical Gas fired hot blast stove factory The existing pipes and radiators in China need to be observed by professional engineers and installation personnel to determine whether they can continue to be used. If the service life is long, the heating system may scale more. It is generally recommended that the user replace it to obtain better heating effect.

The waste heat boiler for hazardous waste incineration is an important part of the hazardous waste rotary kiln incineration system. The heat source is the high-temperature waste gas containing strongly coking and cohesive ash after hazardous waste incineration. Liaoning Gas fired hot blast stove Generally, this type of waste heat boiler adopts single flue or multi flue layout, and convection heating surface is arranged in the flue. During operation, strongly coking cohesive ash is easy to adhere to the convection heating surface, leading to flue blockage, affecting the safe and normal operation of the waste heat boiler. According to the characteristics of hazardous waste rotary kiln incineration system, a kind of waste heat boiler with special structure suitable for the system was developed, which successfully solved the problems of ash deposition, wear, air leakage, corrosion, etc. vertical Gas fired hot blast stove factory The water circulation mode of the waste heat boiler is natural circulation. The working medium directly enters the drum, then is led out from the drum, flows into each membrane water wall through the downcomer, is heated here, then led back to the drum through the steam conduit, and is separated by the steam water separator, and then led out of the drum saturated steam with rated parameters.

The starting of gas-fired boiler shall be carried out according to the operating procedures. The following is the accurate starting process of the analyzed gas-fired boiler: turn on the main power supply, start the gas-fired incinerator, and close the vent valve on the drum when it emits steam. Liaoning Gas fired hot blast stove Check the manhole, handhole flange and valve of the gas boiler. If any leakage is found, fasten them. If leakage occurs after fastening, shut down the boiler for maintenance. When the gas pressure of the gas boiler rises by 0.05~0.1MPA, make up water, blow down, check the experimental water supply system and blow down equipment, and flush the water level gauge together. When the gas boiler pressure rises to 0.1~0.15MPA, flush the pressure gauge trap; When the gas pressure of the gas-fired boiler rises to 0.3MPA, turn the "load high fire/low fire" knob to "high fire" to strengthen incineration. When the pressure of the boiler rises to 2/3 of the operating pressure, start pipe warming and air supply, slowly open the main steam valve to prevent water hammer. vertical Gas fired hot blast stove factory When the drain valve emits steam, close it. After all the drain valves are closed, slowly open the main gas valve to fully open, and then reverse it for half a circle. Turn the "Control of gas incinerator" knob to the automatic gear.
