Generally, natural gas is often cheaper than oil for boiler fuel, primarily due to lower extraction and distribution costs. Additionally, gas boilers tend to be more efficient than oil boilers, resulting in further cost savings over time. However, prices can fluctuate based on market conditions, location, and availability, so it's essential to compare current rates in your area for a definitive answer.
A tangentially fired boiler has between 4 and 8 burners, placed in the corners of the boiler. These are sometimes angled vertically to maximize impingement of the flames. They are fired into the center of the boiler, not directly into the center, but at the wall to adjacent to them. This causes the flames to swirl inside of the boiler, causing an even distribution of flame throughout the boiler. This is shown pretty well here: http://www.alstom.com/power/coal-oil/utility-boilers/firing-systems This website also has a lot more detail than previously provided.
Use of water in a refinery is makeup for boiler feed. The chief uses of steam are for stripping, steam distillation, and vacuum distillation. The steam comes in contact with the products in these operations, and generally the steam condensate is so highly contaminated that it cannot be reused for boiler feed or for other purposes. Steam is also used for process heating, for pumping, and, in some refineries, for generating electric power
No, LPG fuel is not renewable. This is because LPG (Liquid Petroleum Gas) is recovered from the natural gas in oil wells, and since oil is not renewable neither is LPG.
About the most common application of flue gas is as a heat source. Recall that flue gas is the stack gas from plants fired with combustibles (coal, oil, gas, biomass, etc.), and it exhausts into the atmosphere. We spend a lot of money monitoring stack gas to keep the combustion process as tightly controlled as possible. That minimized emissions. The heat in the stack gas can be used to heat water or the like, and the preheated water can then be fed back into the boilers to create the steam that drives the turbines that generate electric power (which is one example, but a common one). The heating of the (boiler) feedwater with the flue gas increases the efficiency of the whole operation. It's classic steam cycle power generation, and the preheating of feedwater within the stack (by the flue gas) is a time-proven tactic to reduce costs.
Honestly, compressed natural gas is more fuel friendly than propane since propane is known to cause more pollution due to fuel outsourcing from oil.
is gas cheaper than oil
It depends on the current market prices, but generally, gas is cheaper than oil.
The cost of a boiler that runs on natural gas versus oil is similar. But, in the long term, you will save money by buying the natural gas boiler because the cost of natural gas is significantly less than oil. In addition, natural gas is cleaner and better for the environment.
Its a Boiler that is fitted with two or more heating sources. Say Gas and Oil Fired
Cheaper than what?
For vehicles, electricity has a lower cost per mile than gasoline. For home use, electric heating units are cheaper than those that use oil or a mix of oil and gas for home heating. Overall electricity can be created in more ways than gasoline so there are more sources of it whereas gasoline and petrol production is based on the cost per barrel of oil.
Gas is cheaper to maintain, burns cleaner, but is more explosive if it leaks. I would also base the final decision on how many heating days the area averages, fuel oil tends to be a bit cheaper by the gallon, if I remember correctly.Aacturally for the hot water boiler or horizontal hot water boilers , we can charge it by electric , it is more convenient,It is equipped with advanced touch screen controller, digital prosecution system to achieve automatic control of boiler operation, Zhangjiagang Wilford thermal Co,.ltd is committed to be the expert of this field.
Natural gas used to be much cheaper, but with rising oil prices its about on par with electric now. The price for gas will most likely continue to rise though. So, electricity is cheaper.
yes
Gas heaters are better. Gas heaters are cheaper and have a cheaper and easier maintenance, however oil heaters are less prone to leakage, but are more expensive and now steadily becoming outdated. Furthermore, oil heaters leave behind an odor and fewer personnel these days know how to deal with them, while most personnel that deal with heaters are trained in the matters of gas. Finally, gas is generally cheaper as oil heaters are far more expensive.
because it is less in quantity
Over the last several years the prices for oil have been cheaper that gas. There have been periods where the price of oil has risen sharply. Both are efficient methods of heating but a lot of people have been converting to gas recently because of incentives by gas companies. In reality, they are about the same. A lot of gas companies try to fool their customers into thinking that gas needs less maintinence/is cheaper than oil, which tends to be untrue. It is recommened for either device that one keeps a yearly maintenence schedule.
