Liquefied natural gas water heater
Safety performanceAs long as the master technology principle, the correct procedure in accordance with the operating personnel with a serious and responsible attitude, after the completion of the transformation of the safety performance inspection of gas water heater, of course you don't have to worry about security issues, a qualified after the transformation performance does not occur naturally change, you can rest assured that use. But why there are still online netizens have said "my water heater transformation winter after the water is not hot enough, a small fire cannot catch fire, and water heater repair", we analyze the three reason is that the water is not hot enough mainly because of the transformation parameters did not have a good nozzle parameters are incorrect. A small fire when the water heater cannot catch fire mainly affect the parameters of gas valve core hole, a lot of reform personnel did not notice the valve hole parameters also need to be rebuilt, or know to change because of the influence is not big but deliberately do not change the trouble, in summer, they found a small fire to beat the fire off a small fire at lower temperature. Therefore, it is very important for the transformation to be transferred to the minimum firing position to meet the requirements of ignition performance. In addition, the summer temperature can not drop down can also be tested through the smallest firepower, timely solution! Finally, it is clear that the liquefied natural gas water heater can be changed into natural gas, the natural gas water heater is also feasible to transform into liquefied petroleum gas! Shenzhen in the use of natural gas water heater 70% is the transformation of the new purchase of the 30% (to buy the use of natural gas).
Technical principleAs long as the master of the gas composition and principle of gas water heater principle, any gas water heater can be changed to the use of any gas source, gas water heater can be converted into liquefied gas, liquefied gas water heater into natural gas also is feasible, but some special gas transformation technology needs to consider whether the gas water heater is the gas channel required to meet the requirements of gas flow, such as a liquefied gas water heater modification of adult gas, one thing that is particularly difficult and renovation costs are particularly high, because of the low calorific value gas, nozzle aperture, so the traffic is particularly large, can not be achieved using flow the requirements of liquefied gas water heater general transformation, so the transformation of the way in reality is not exist. In reality, the existence of natural gas is the main water heater to liquefied gas (bottled gas) or liquefied petroleum gas to natural gas more, and these two kinds of gas to the heater gas flow requirements are not too high, so after the transformation in use can meet the required performance requirements.
Different manufacturers of different specifications of water heater gas replacement replacement parts are not the same. The nozzle, an air adjusting plate, burner, wind gear, two possible replacement, upstairs that is not so simple, and there are two nozzle diameter and height parameters, different models are not the same. If the correct replacement is best to consult manufacturers, if you can get to Caution!, the nozzle diameter reduced, will be two times the high pressure, to ensure that no yellow flame flame almost, if not change the nozzle to consider other.
Method for changing natural gas water heater by liquefied gas water heaterLiquefied petroleum gas (petro) (LPG) gas burning natural gas (NG), due to differences in calorific value of liquefied petroleum gas and natural gas, have a fever the amount of liquefied petroleum gas is about 22000 kcal / m3 (M3), natural gas is generally 8500 kcal / m3; and the pressure is not the same, natural gas is about 2000 kPa, liquefied gas about 2800 kPa; both mixed with air in the combustion (H connected n) with hybrid ratio is also different. So the gas output two appliance is different.Using liquefied petroleum gas burner, the valve orifice diameter is generally 0.8mm, aperture of natural gas appliance need is 1.2mm. Liquefied petroleum gas burner to burn natural gas, can put the original nozzle unloaded, CF nozzle to buy a useful natural gas back mounted on the line (buying tips: natural gas nozzle diameter approximately inserted into a pin), otherwise buy real nozzle for liquefied petroleum gas loading. Straight shank twist drill can also with a diameter of 1.2 liquefied petroleum gas water heater to natural gas mm, wary of reaming to vent, Gas Co to do so is ranju. After the reform of the flame should be pure blue, not yellow.
