lk s cast iron triple boiler table

Exhaust heat loss factors determines the size of the three: the exhaust gas temperature, excess air coefficient, and the cold air temperature. Wherein the excess air ratio of gas lk s cast iron triple boiler table is a major factor. Excess air ratio is too large a tremendous waste. A lot of cold air into the furnace inside, first reducing the temperature of the furnace, combustion conditions become unstable, but also increases the flue gas volume, increased heat losses. Calculations show that when the excess air ratio is increased to 3.0 from 2.0, heat losses to 4.5%. While increasing the drum Fan burden, so power consumption increases. In order to improve the gas boiler thermal efficiency, we must pay attention to and raise awareness of the serious dangers for the high excess air ratio caused by combustion in the regulation strictly control the excess air ratio, which is currently heating industry in areas often overlooked.

Natural gas industrial lk s cast iron triple boiler tables produce condensate water hazards natural gas industrial boilers produce condensate water hazards natural gas industrial boilers produce condensate water hazards 1, the corrosion of condensate water boiler heating surface major harm to the natural gas industrial boilers is the corrosive effect on the heating surface of the boiler. Condensate corrosion WNS rear of the boiler heating surface of the bottom of the tube focus, mainly iron oxide corrosion products. Condensate corrosion can cause intense side wall thinning, strength weakened. (1) condensation with the flue gas evolution corrosion, some CO2 is dissolved in the condensed water, CO2 generated in case of weak electrolyte H2O H2CO3, ionized hydrogen ions, so that a weak acid condensate, and another part of the nitrogen oxides and containing a very small amount of sulfur dioxide dissolved in the condensate, enhances the acidity of the condensate, the pH of the condensed water as in table 1 were lower than the position of the drum 4.3. iron hydrogen evolution corrosion can occur in the acidic solution, and the strong acid, the reaction The faster rate. (2) Since the oxygen etching gas during combustion boiler need to ensure a certain air ratio, combustion flue gas contains oxygen. When the steam condenses, some oxygen will be dissolved in the condensed water, causing corrosion of the metal heating surface of the oxygen. 2, when the cross-sectional area to reduce the flue gas flow type gas boiler industrial boilers operate at low load, the heated surface of the flue gas, the condensed water gathered in the smoke tube, the resulting corrosion products accumulate in the bottom of the tube, even clogging of the pipe part, thus reducing the flow area of ​​the flue gas, the flue gas resistance increases, and increase in power consumption of the blower. 3, the furnace temperature is lowered, damage to the burner within the examination of natural gas in industrial boilers, often find a certain amount of condensed water. We found condensate discharge tube boiler such severe congestion, resulting in condensed water in the lower furnace does not discharge, and refluxed for aggregation. When the boiler is started, the heat accumulated in the furnace absorbs the condensed water and evaporated fuel combustion, thereby reducing the furnace temperature. If the furnace condensate accumulated too much, and even dipped into the burner, causing damage to the burner. Suddenly turn off the boiler, the boiler does not start, because the burner too much condensation water immersion, affecting the safe operation of the boiler. 4. Effect of boiler condensate generated on the heat sealing material penetrates into the sealing material of the boiler insulation, the point of the arrow indicated gas tank gas boiler WNS industrial boilers. Sealing condensed water immersion insulation material for a long time, the insulation effect will be weakened or even physical damage, increased heat loss. Meanwhile, the condensed water will make the sealing material deformation aging, sealing capability weakened, leading to a certain amount of flue gas emissions, which not only be dangerous, can also cause a certain amount of heat loss.

Advantage of Fire Tube Boiler

From a maintenance standpoint, fire tube boilers are typically have lower operating costs comparable to a similarly sized water tube boiler. Fire tube boilers have easy access to the boiler’s firesides and tubes can easily be replaced without additional repair of the boiler. Although fire tube boilers are smaller in design, they have a larger water volume than similar size water tube boilers, causing them to take longer to bring up to operating temperature from a cold start. Once a fire tube boiler is started up and is operating at its desired pressure, a fire tube boiler can handle a sudden upward load surge better than a water tube boiler because of the large steam disengaging area. The drawback to this feature is once the pressure of a fire tube is dropped, it takes longer to catch back up. With less water volume, a water tube boiler has the ability to follow load swings more precisely and generally has better turn down than a fire tube boiler.

Best Cast Iron Boiler? Heating Help: The Wall

A cast iron boiler is much less sensitive to low flow rates than a low mass type. Think of the last 60-80 sq ft room you saw on a zone all by itself and what the boielr did when that zone called for heat. A typical cast iron boiler is a much less complex design in both the heat exchanger and burner design.
