Hydrostatic test of low nitrogen burner

1. Check the following components before the hydraulic test of the low nitrogen burner: external inspection of the heating surface pipe, air barrel and header. The outer side of the air duct and header should have a good insulation layer, and some temporary fixing brackets required for component maintenance have been removed to avoid additional stress due to high temperature and inability to expand freely during installation. The heater is filled with water. Apart from that, are there other things that hinder the free extension of components? the
2. Other aspects: whether all water level gauges, pressure gauges, relevant valves and other heating furnace accessories are installed, and whether expansion indicators such as blowers, headers and pipes are installed. What are the test items for low nitrogen internal combustion engine hydrostatic test? the

3. During the hydraulic test, when the working pressure is reached, the tightness of the pressure-bearing parts should be carefully checked. In terms of tightness, check whether there is leakage on the surface of welds, protrusions, manholes, flanges, other joints and pressure-bearing parts. Leak detection can be observed with the naked eye, but it is not suitable to see clearly. It can also be checked manually. In some particularly difficult places, it can also be checked by reflection from a mirror. the

4. What is the hydrostatic test procedure for the Low Nitrogen Oxide (NOx) Burners? Open the water inlet valve of the heating furnace, start the feed water pump or other water pumps, and slowly send water into the heating furnace. The water used in the hydrostatic test is deoxygenated water, but if there are difficulties on site, chemical treatment can also be carried out. The temperature of the water should not be too high or too low, usually slightly higher than room temperature.www.burners-china.com
