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.
Chevrons in a boiler refer to the angled or zigzag-shaped elements found within the heat exchanger or economizer sections. Their primary function is to enhance heat transfer efficiency by increasing the surface area and promoting better fluid distribution. This design helps to maximize the contact between the flue gas and the heat transfer surfaces, leading to improved thermal performance and energy efficiency. Additionally, chevrons can assist in reducing fouling by directing the flow of gases more effectively.
The design formulas for a water tube boiler primarily involve calculations for heat transfer, pressure drop, and thermal efficiency. Key formulas include the heat transfer equation ( Q = U \cdot A \cdot \Delta T ), where ( Q ) is heat transfer rate, ( U ) is the overall heat transfer coefficient, ( A ) is the surface area, and ( \Delta T ) is the temperature difference. Additionally, boiler efficiency can be calculated using ( \eta = \frac{Q_{output}}{Q_{input}} ), while pressure drop can be estimated using Darcy-Weisbach or Hazen-Williams equations, depending on the fluid flow characteristics. Proper material selection and structural integrity must also be ensured through stress analysis based on operating pressures and temperatures.
when two material are brought to contact,so the space where they made contact is called interfacial area,it is usually considered in heat transfer calculation

No, it is not okay to put your oil central heating boiler outside. It should be in an enclosed area.
There is a wide variety of electric boiler ratings. This is because an electric boiler rating is based on the square foot area of the heating coils. The larger the system the more heating power will be needed.

Common signs of a boiler leak include water pooling around the unit, a drop in boiler pressure, unusual noises coming from the system, and visible corrosion or rust. Potential risks of a boiler leak include water damage to the surrounding area, reduced efficiency of the boiler, and the possibility of carbon monoxide leaks if the boiler is not functioning properly.
The heat transferred from flames to a boiler depends on several factors such as the temperature of the flames, the surface area of the boiler, and the efficiency of heat transfer. In general, the heat transfer occurs through convection and radiation, with the flames heating the boiler's surface which then heats the water inside.
I'm not sure what you mean by the definition but here is the formula: Area = ½ × b × h
