At present, the research and development technology of gas boilers is very mature. The boiler has obvious advantages of stable operation and less pollutant discharge and energy saving. However, if the boiler is not used for a long time, it is necessary to maintain the boiler to maintain the normal operation at the subsequent startup.
As we all know, the stable operation of the natural gas boiler can significantly optimize the operation of the boiler, improve the efficiency of the boiler, and effectively reduce the operating cost of the boiler after effective maintenance. So, what factors will affect the stable operation of natural gas boilers?
Pickling is the main method for removing a large amount of oxidizing substances and corrosion products inside a gas boiler, and also has the effect of eliminating scale. The pickling process is usually carried out after 1-3 weeks of boiler operation.
For an industrial boiler with reasonable structural design, its thermal efficiency is relatively high, and its exhaust gas discharge temperature is relatively low, so we must carefully consider the boiler property report form when purchasing the boiler.
Gas consumption per hour of natural gas boiler = boiler thermal efficiency / natural gas calorific value / boiler efficiency. The higher the efficiency of boiler use, the less gas consumption, which has inverse relationship between the two. Boiler efficiency has become a key point in assessing boiler quality.
The flue gas first enters the cyclone dust collector which acts as a primary dust collector to make the large dust particles in the flue gas settle down. The cyclone dust collector is a dust removal device which uses the centrifugal force generated by the cyclone flow to separate the dust particles from the air flow. Afterwards, the flue gas enters the wet scrubber dust collector which is a circular-type cylinder. The circulating water enters the dust collector from the upper overflow tank to form a uniform water film on the inner wall of the dust collector. The flue gas is induced tangentially or spirally from the lower part of the cylinder and rotates in the cylinder. Under the influence of the centrifugal force, the dust particles are separated from the flue gas and then the flue gas is also spirally led out from the top of the cylinder. The dust particles are thrown to the water film, transferred to the bottom and finally discharged from the dust port.
In the operation of gas-fired steam/hot water boiler, it need continuous water supply to ensure the water volume in the drum. Once water shortage occurs, it will cause the boiler dry burning problem, which will further result in the boiler failure and other problems.
