What Is Your Natural Gas Boilers?

As the name indicates, natural gas fired boilers use natural gas as fuel. In other words, they run on natural gas, which is one of the least contaminated fuels used for boiler operation. Thus, it is no surprise that natural gas is rapidly replacing coal as the fuel of choice.

Natural gas consists mostly of methane (typical >85%), with the balance varying being amounts of ethane, propane, butane and some inert components (nitrogen, carbon dioxide, and helium). Natural fired steam boiler doesn’t generate dirty emissions or causes unpleasant odours when burning, making it an eco-friendly alternative.

What Are The Pros Of Your Commercial Natural Gas Boilers?

There is a range of decisive advantages of gas steam boilers, but here are the most significant reasons to know:

  • Save energy:
    Natural gas boilers for sale help to save energy. They use the least amount of fuel compared to electric and oil-fired boilers, making them the most economical choice in terms of fuel cost.
  • Save money:
    A major attraction to propane steam boiler is that they can help cut costs. Because it is highly efficient, it will cost less to heat your facility. Plus, its units are relatively cheaper when compared to other types of boilers.
  • Help the environment:
    Natural gas is a clean fuel that emits a very small amount of flue gas after combustion. Because it doesn’t produce hazardous gases and fumes in the use of the process, it is a great option for the environment to reduce environmental pollution.

In all, if you’re having trouble determining the size that’s right for you, reach out to us at Yongxing to help out.

For Natural Gas Boilers, How It Works?

One of the questions many people often ask is ‘How does a natural gas boiler work?’ A gas heat boiler is essentially a water tank mounted over the top of a massive heat element. The heating source (in this instance, natural gas) is pumped through a pipeline, either from a city line or a propane tank.

The natural gas is ignited by a pilot light that heats the reservoir tank of the boiler. When the thermostat signals it to or when you turn it on manually, there is a free flow of gas into the chamber where it is ignited. The mechanism is usually a smaller piece of gas piping filled with many holes to create a flame jet effect.

Once the flame is formed, it is maintained to heat the water tank above it to the desired temperature. When it gets to the proper temperature, an electric pump moves it out of the tank and via a series of pipes that run throughout the building to a set of radiators.

By the time the water returns to the boiler again, it has lost a lot of heat already, and the boiler reheats it again.

How About Your Natural Gas Boilers Burner?

The burner is a critical component of your boiler as it performs the function of providing the heat input by combustion of the natural gas. Gas is supplied to the burner at a pressure sufficient to induce a supply of air to mix up, leading to combustion. The burner does five major things:

  • Delivers gas to the combustion chamber
  • Delivers air to the combustion chamber
  • Mixes the natural gas and air
  • Ignites and burn the mixture
  • Removes the products of combustion

What Is The Design Of Your Natural Gas Boilers Furnace?

Does Your Natural Gas Boilers High Efficiency?

The simple answer is yes.

Gas-fired steam boilers burn natural gas or liquefied petroleum gas as a fuel to produce steam.

This type of boiler is very efficient and is usually able to produce steam at 90% efficiency.

However, this does not mean that it achieves 100% efficiency every time. Occasionally, there are problems that can reduce efficiency.

For example, if the water level in the boiler is too low, this can result in some of the energy being wasted.

Also, if low-grade natural gas or LPG is used, the efficiency can be reduced.

Fortunately, it is possible to maximize the benefits of a boiler by using and maintaining it properly.

Under normal conditions, a gas-fired steam boiler can typically produce steam at 94-96% efficiency if it uses high-quality fuel and maintains a normal water level.

As stated earlier, At Yongxing Boiler group, natural gas steam boiler efficiency is higher than other types of boilers.  They offer you excellent results higher than 94% and help in producing hot water and steam for industrial purposes.
