Electric steam fire tube boiler package type needs to pay attention to what use? Electric steam boiler needs to pay attention to what use? Using electric boilers should pay attention to prevent water shortages check: When using electric boilers must pay attention to the amount of water in the system is sufficient, because the job is electric boiler to heat water by electricity, so as to achieve the purpose of warming. If the water is not enough, it will inevitably lead to electric boilers work flow, and damage inside the original electric boiler, there may also be a serious security risk, so in a timely manner to solve the water shortage in the electric boiler system is still very important. Check the electrical system of the boiler water level from time to time, ensure that the water has been able to solve this problem very easily above the water line and electric boiler itself as well as automatic protection function, the alarm automatically, so please do not worry too much, regular electricity boiler, the system checks it. Electric boiler tube reasons: 1, the heating tube during use, the voltage is unstable, while voltage increases as the current increases the heating tube cause breakdown. 2, using heating tube during dehydration can cause breakdown of the heating tube; 3, the temperature control system malfunction, breakdown can also cause the heating tube; 4, heated tube surface fouling, reach a certain receiving, heat is not good, will heating tube causing breakdown.

Henan present gas fire tube boiler package type fuel ratio control and debugging problems 1.Henan gas boiler fuel ratio irrational: ejector conventional gas boiler burner, resulting in the air-fuel ratio adjustment can not maneuver. Most of the gas boiler uses a mechanical blower burner, causing the air-fuel ratio irrational factors are the following: air-fuel ratio unreasonable divided into two situations: when the excess air from time to time, there will be plenty of cold air is superfluous heating, resulting in increased energy boiler, boiler thermal efficiency decreased; when there is insufficient air, there will be incomplete combustion phenomenon, resulting in the boiler thermal efficiency. 2. Boiler factors Henan gas air-fuel ratio include: changes in ambient temperature lead to changes in air density and the density of the gas, fluctuation of gas pressure in the pipe causes the amount of gas injected into the furnace is increased or decreased, the throttle opening degree at some time after the operation offset, etc., can lead to imbalance in air-fuel ratio. These factors are always constantly changing, therefore, it is necessary to adjust the air-fuel ratio is continuous, uninterrupted. Autoregulation limitations burner: Burner simple conventional air-fuel ratio adjusting means arranged, by adjusting the air-fuel ratio mechanical linkage, environmental factors can not solve the problem of air-fuel ratio variation due to frequent fluctuations. If the air-fuel ratio imbalance, the burner is not self-diagnose and self-correction function. 3. Henan gas boiler fuel ratio control and debugging: In most cases, was observed with the naked eye are commissioning adjusting the fuel valve and the air damper opening degree of flame color and shape manually, it can not determine whether the air-fuel ratio in an optimal position. Even at the time of commissioning flue gas analyzer to adjust the air-fuel ratio is good, but due to the many changes in the external environment factors will lead to continued volatility combustion conditions, even a one-time adjustment of the air-fuel ratio accurately, but after a short time (a few hours or a few days means after), will soon air-fuel ratio imbalance.
Oil-fired fire tube boiler package type body heating surface long-term maintenance methods: dry and wet. Dry maintenance method should be adopted when furnace is stopped for more than one month, and wet maintenance method can be used below one month after furnace shutdown.
1 dry maintenance: After the oil-fired boiler shut down, remove the pot water, thoroughly remove the internal dirt, rinse clean. Dry in the hearth with a light fire (be careful not to use a fire), then pack the 10 / 30 mm lump of quicklime into a tray and place it in the pan, without contact with the metal. The weight of quicklime is calculated in terms of the volume of the drum per cubic metre of 8kg, and the weight of the quicklime is calculated in terms of the volume of the drum per cubic metre of lime. Then close all manholes, hand holes, piping valves, check every three months, replace quicklime if crushed into powder, and remove quicklime and tray when oil-fired boiler re-operates.
2. Wet maintenance: After the oil-fired boiler is shut down, the boiler water should be cooled below 70 ℃, and the internal dirt will be thoroughly removed and washed clean. All the manholes, hand holes, pipeline valves and so on will be closed tightly, and completely isolated from the oil-fired boiler in operation with blind plates.
Boiler Types According to tubing methods Ther e are two main types of boiler Fire tube boilers and Water tube boilers. Fire tube boilers are those boilers in which fire or flue gases are inside of the tubes and water is on the shell side.Learn More
High capacity package boilers B&W also provides higher capacity package boilers for both oil and gas firing. These units feature multiple burners for increased capacity.

In a water-tube boiler, it contains a minimal amount of water at any given time. It may be just one-tenth the volume of a fire tube boiler, which requires a larger volume of water to act as a heat shield so that metal in the boiler doesnt melt and create problems. When fire tube boilers run low on water, the metal in the boilers shrinks.Learn More
