With many years of research experience in the fast side of the swimming pool boilers wholesalers 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.
Burner gas swimming pool boilers wholesalerss were burned there a way to solve the gas boiler has been running well, but this can not be used suddenly, after checking to confirm that the burner is damaged up. What are the reasons can cause burner gas boiler is burned? For such problems, what can be the solution? Gas boiler burners burn have a relationship with a number of factors, for example, there may be a way to let the boiler temperature deviation high, has reached the upper limit of the allowable range, so that the high temperature flue gas furnace radiation heat of the burner is enhanced, the wall temperature of the burner nozzle is increased burning. It is also possible with a gas flame furnace boiler deflected about the base, because after testing found furnace temperature and burner nozzle with uneven distribution of temperature, wind speed and orifice layer with the four corners of boiler burners significantly uneven. In addition, gas burner boiler equipment standards at fault, not the end of a stable tangential firing, but also so that the other main reason for the flame base skewed. When adjusting the gas boiler, if the wind speed control of the secondary is too small, it will lead to too close the gas fire, the burner nozzle so that thermally deformed until failure. Further, when the adjustment is not timely gas boiler load changes the level of the upper orifice of the secondary throttle will be cooled so that the burner is not burning. After the burner for damage affecting the entire gas-fired boiler it is very large, so users in the usual course of adjustment is necessary to strengthen the control of the boiler, including the timely and quality control gas pressure changes in circumstances, gas and hot air to ensure reasonable ratio; when viewed ignition gas, adjust the size of the second damper, to change the operating angle of the operating layer when necessary; when the low load conditions change, to adjust the negative pressure combustion furnace, adjusting gas, the ratio of hot air, to ensure that the furnace coordination with the flame does not skew the layers of good gas opening. Further, the material can be appropriately improved gas burner in the boiler, it is recommended to select superior steel materials, wear resistant and adding functionality. Selection of swirler vanes refractory steel material, so to avoid burning due to swirling vanes configured fall burner opening deformation damage. In addition, be sure to strict accordance with the drawings need to adjust the gas boiler burners standards to ensure tangential firing flame in the furnace, ensure the stable operation of the gas boiler. On the practical application of gas-fired boiler There are many different applications and different habits, a variety of problems, if users also encountered other problems, you can consult our technical staff, to welcome the advice, we will the attitude of enthusiasm for your service needs.
Recently, Shaanxi Province issued a notice "issued four Battle 2019 program of work". Programs that: improve the mechanism of heating prices, heating prices reasonable development of clean, green electricity implement ultra-low emissions coal-fired power plants, a comprehensive clean canceled preferential tariff class of high energy-consuming industries unreasonable prices and other preferential policies. Off Area ban coal stove, substantially eliminated cogeneration heating pipe network coverage in the range of coal heated oven (furnace).
According to focus on the use of coal and clean use of principles, focusing on reduction of non-coal for electricity, increase the proportion of electricity from coal. Increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate coal-fired boilers and scattered inside the pipe network coverage. Actively implement alternative heat source, deadline for shutting down the Guanzhong area below 100,000 kilowatts thermoelectric ratio does not meet the national standard or alternative heat source thermal units. Optimal operation mode cogeneration units, strictly implement the "hot set electricity."
How to control swimming pool boilers wholesalers pressure correct? With the rapid development of the industry boiler, boiler becomes more secure, reliable, boiler explosion event frequency also declined. But this does not mean that the boiler explosion accident will never happen, an accident will cause serious irreversible effects to society, individuals. It is important to pay attention to is the pressure of the boiler running part, stay on top of the boiler pressure gauge changes, the boiler accident strangled in the cradle. Mainly refers to the boiler pressure boiler abnormal overpressure occurs, burst pipes, water hammer phenomenon, small will be analyzed according to the above points. A boiler overpressure overpressure is generated in a boiler pressure during operation is not normal, when the pressure exceeds the allowable range of the rapid increase in the specific performance of gauge pointer exceeds the allowable working line (typically a red indicator line), the operation of the safety valve occurs , the pressure continues to rise; also issued overpressure alarm signal to start the overpressure protection interlock mechanism; steam temperature increases to reduce the steam flow situation will change. Faced with this situation can be handled by the following four points. 1, to reduce the amount of combustion of the fuel, or valve manually open the purge valve for blowing off steam. 2, to increase the amount of water, treated sewage while strengthening the lower drum, thereby reducing boiler water temperature reaches the purpose of reducing the pressure in the boiler drum. 3, valve failure or if the pressure gauge has been damaged, should activate the emergency shutdown device to ensure safety valve or pressure gauge remains before starting the boiler is running normally again. 4. Finally, when taking blood pressure measures, we must remember that the buck can not be carried out rapidly, so that an explosion may occur during depressurization. Second, the phenomenon and the reasons for boiler tube boiler tube details see: a boiler superheater and reheater and its treatment method when the damage occurred. Third, the boiler water hammer water hammer refers to any polymerized condensate pipe sagging low water together to form a block, as the steam flow rate will accelerate the movement of steam, the block when the water changes direction suddenly, the kinetic energy of the water will be released, issued similar strong percussion sound of the pipe. Water hammer occurs when the boiler is usually accompanied by the following phenomena. 1, the boiler and the pipe connections clashed with a certain rhythm, accompanied by strong vibration water pipes or steam pipes. 2, the pressure gauge wobble frequency noise and vibration consistent. 3, when the situation is very severe, may lead to breakage of the connecting member of the flange, weld, valves and the like. Face water hammer phenomenon can be treated in several ways. 1, to reduce the amount of steam supply, the main steam valve can be closed when necessary. 2, a hydrophobic treatment open superheater header pipe and the steam trap on. 3, so appropriate in order to maintain the normal water level of sewage. 4, to ensure water supply and boiler water quality, prevent priming phenomenon. 5, the water hammer processed, to check use of pipes and connections butler, flanges, etc., on the timely replacement of damaged place.
