With the popularity of natural gas water heaters, many old-fashioned water heater consumers will choose to convert it into gas water heaters, especially liquefied gas water heaters, but for our lay friends, it is not easy to modify them, especially Not sure if it can be modified? After modification is not safe? How to modify and other issues. So, can liquefied gas water heaters change natural gas water heaters? Liquefied gas water heater to change natural gas water heater how to modify it? Let's take a look with Xiaobian.
One, liquefied gas water heater can be changed to natural gas water heater
1, the principle of technology
As long as you master the principle of gas components and the principle of gas water heaters, any gas water heater can be changed to use any gas source. Natural gas water heaters can be changed to liquefied gas, and liquefied gas water heaters can be changed to natural gas, but only some special gas reforms. The technology needs to take into account whether the gas passage of the gas water heater itself can meet the requirements of the required gas flow, for example, a liquefied gas water heater is converted into artificial gas, which is a particularly difficult and particularly high transformation cost because artificial The calorific value of the gas is low, and the nozzle has a large aperture, so the flow rate is also particularly large. After the general liquefied gas water heater is reformed, it cannot meet the requirements for using the flow, so this reforming method does not exist in reality. The reality is that there are many natural gas water heaters that change from liquefied gas (bottled gas) or liquefied petroleum gas to natural gas, and these two gases are not too high for the gas flow rate of the water heater, so they can be used in the application after the transformation. Required performance requirements.
2, safety performance
As long as we mastered the principle of retrofitting technology, the operators used a serious and responsible attitude to operate in accordance with the correct procedures, after the completion of the transformation of the safety performance of gas water heaters, of course, do not have to worry about safety problems, once the transformation of the performance is not natural changes , you can use it with confidence. However, why do Internet users still say that “when my home water heater is not hot enough after the reconstruction of the water heater in the house, the fire will not work if the fire fails to heat the water heaterâ€, we analyze the above three reasons. The reason why the water is not hot enough is mainly because of the parameters of the renovation. Not mastered, nozzle parameters are incorrect. When the water heater fails to catch fire during a small fire, it is mainly influenced by the parameters of the gas valve core hole. Many reformers do not notice that the valve hole pinhole parameters also need to be rebuilt, or they know that it is necessary to change it because the impact is not large enough to deliberately change the trouble. In the summer, when it was necessary to turn off the heat and lower the temperature, it was found that the small fire could not reach the fire. Therefore, it is very important after the transformation that it is necessary to tune to the minimum fire position to test whether the ignition performance meets the requirements. In addition, the summer temperature drop can not be tested by the minimum firepower, timely solution! Finally, it is clear that the liquefied gas water heater can be changed to natural gas, and the conversion of natural gas water heaters into liquefied gas is also feasible. After the correct transformation of the water heater is safe, there is no difference in the use performance after correct transformation!
Second, liquefied gas water heater to natural gas water heater method
When liquefied petroleum gas (LPG) burning appliances are changed to natural gas (NG), the calorific value of liquefied petroleum gas and natural gas varies greatly, and the burning capacity of liquefied petroleum gas is approximately 22,000 kcal/m3 (m3). Natural gas is generally 8,500 kcal/cubic meter; and the pressures of the two are also different, with about 2000 Pa natural gas and about 2800 Pa liquefied gas; the mixture ratio between the two is also mixed with air during combustion. Differences. Therefore, the gas output of the two types of burning appliances is different.
With liquefied petroleum gas burning appliances, the outlet diameter of the valve is generally 0.8mm, and the required diameter of the natural gas burning appliance is 1.2mm. When the liquefied petroleum gas burning appliance is changed to natural gas, the original nozzle can be detached, and the reciprocating nozzle can be replaced by buying a nozzle that is actually used for natural gas. (Purchase Tip: The nozzle diameter of the natural gas is about exactly the same as inserting a pin. ), on the contrary, buy back the nozzle that is actually used for liquefied petroleum gas. You can also use a 1.2 liquefied petroleum gas water heater to switch to natural gas mm straight shank twist drills, and recklessly expand the hole, the gas company to change the gas appliance are doing so. The flame after the reform should be pure blue and not yellow.
Can you change the gas water heater to a natural gas water heater? How to modify? It's a simple introduction here, and I hope to help you. For more information, please visit this website. Stay tuned.

Zhejiang Sealand Technology Co., Ltd. is a trustworthy manufacturer of Alcohol Mass Flow Meter, Alcohol Mass Flowmeter, Alcohol Coriolis Meter, Mass Flow Meter Alcohol, Coriolis Mass Meter Alcohol, ATEX, IECEx & CE approved.
Sealand meter is designed and produced according to world`s latest Coriolis technology with better appearance, stability and accuracy to measure mass flow rate of a fluid traveling through a tube, widely applied to alternative energy, oil & gas, chemical, food & beverage, industrial energy, marine, power, pulp & paper, water & wastewater industries, etc.
Mass flow meter measures the mass based on Coriolis effort. The operating principle involves inducing a vibration of the tube through which the fluid passes. The vibration, though not completely circular, provides the rotating reference frame that gives rise to the Coriolis effect. While specific methods vary according to the design of the flow meter, sensors monitor and analyze changes in frequency, phase shift & amplitude of the vibrating flow tubes. The changes observed represent the mass flow rate and density of the fluid.
