steam boiler with propane burner

After the steam boiler with propane burner 1. Disable Maintenance selection months boiler shutdown should be used in the above dry desiccant process. 2. Shutdown of 1-3 months can be used sodium nitrite or alkaline process method. 3. boiler stop running, can start within 24 hours, holding pressure method may be employed. For intermittent operation or downtime in the boiler within a week of this method can also be used. But it must be done in the furnace pressure above atmospheric pressure. Found a slight decrease in pressure fire must be timely boost. 4. When the boiler is stopped due to maintenance, the drying method employed. When not required, such as drainage, retention pressure method may be employed. After the boiler overhaul, if not promptly put into operation. It should be based on the length of downtime boiler using appropriate protective measures. 5. wet protection, boiler room temperature is preferably maintained at above 10 ℃, not below 0 ℃, avoid freezing equipment.

In general, the larger the heated area in the overall share of boilers, heat transfer to the boiler fuel combustion more fully, improve fuel efficiency, the side is concerned, enterprises save more fuel.

In production, there are often some thorny problems in boiler operation. Needless to say, the editor for you to sort out the boiler operation common problems and solutions, after learning, do not forget to share with your friends oh. In the process of manufacture, transportation, installation and maintenance of boiler, it is inevitable that some impurities such as dirt, iron chips, welding slag, iron oxide and so on will be produced and glued to the pressure parts of the steam and water system in the process of manufacture, transportation, installation and maintenance. As soon as these impurities enter the steam-water system in operation, they will do great harm to the boilers and steam turbines. Therefore, the boilers before they are installed and overhauled must be chemically cleaned to remove them. Feed-in speed of boiler before start-up Degrees should not be too fast, generally no less than 4 hours in winter, other seasons 2 to 3 hours, especially in the initial stage of water should be slow. The inlet water temperature of a cold boiler is generally at 50 ℃ 90 ℃, so that the difference between the feed water temperature entering the drum and the wall temperature of the drum is less than 40 ℃. If the boiler is not fully cooled, the inlet water temperature can be compared with the drum wall temperature, otherwise, the inlet water speed should be slowed down. The reason is! (1) because the drum wall is thicker and the expansion is slow, the tube wall connected to the drum wall is thinner and the expansion is faster. If the inlet temperature is too high or the inlet speed is too fast, it will cause unevenness of expansion, crack of welding joint and damage of equipment. (2) when water supply enters When the drum is in contact with the lower wall of the drum, if the difference between the feed temperature and the wall temperature of the drum is too large, the speed of entering the water is fast, the upper and lower walls of the drum, the inner and outer walls of the drum will produce a larger expansion difference, resulting in a larger additional stress to the drum. Causes the steam drum to deform, produces the crack when serious. When the temperature of the heated surface is lower than the dew point of the flue gas, when the temperature of the heating surface is lower than the dew point of the flue gas, the steam in the flue gas is combined with the SO2,SO2 to form the sulphuric acid steam, which condenses on the heated surface. The boiler always causes low temperature corrosion of the heating surface first. The cold end of air preheater is prone to low temperature corrosion.

As a leader in the fast side condensing gas boiler, in recent years, provide a clean boiler to Beijing multiple office units, was well received. I units through the preliminary investigation and contrast, select fast boiler, it turns out, party fast product does have quite a good cleaning environmental performance, in line with the Beijing municipal government requirements for air pollution emissions, the use of very at ease. --customer feedback

Reasons why the burner short-cycles, and where to look for

Jun 24, 2014 · When the steam heads down a pipe, it pushes air ahead of itself. If the air can't get out at the end of the pipe (through a vent), the steam will just compress it. The pressure builds, and the burner shuts off on the pressuretrol. The burner short-cycles, but that's not your only problem.
