The operating cost and gas consumption of a gas hot water boiler depend on several factors, including the size of the boiler, its efficiency rating, the cost of natural gas in your area, and how much hot water you use.
In general, gas hot water boilers are more efficient than electric hot water heaters, which can help reduce operating costs. According to the US Department of Energy, a gas hot water boiler with an efficiency rating of 90% or higher can save you about 30% on your energy b...
Gas-fired boilers use gaseous flammable gases (including liquefied combustible gases) as fuel. These gaseous fuels have relatively higher calorific value and less pollutant emissions, and are gradually becoming popular among corporate users.
An Interlock in the boiler’s control system is a programmed or hardwired condition that forces a device to be in a pre-determined or permissive state before the process can continue.
Depending on design pressure, fuel type, either liquid, gas or solid, all steam boiler require interlocks to sequence the operation and to prevent damage to the boiler. Examples of such devices are High or Low Boiler Drum Water Level, Low Boiler Feed Pump Pressure, High or Low Fuel pressure, High or Low Atomization pressure (oil fired), Proof of Ignition, Proof of Flame, FD and/or ID (solid fuel) Fan Motor Operation or combustion air pressure, Damper or Valve position and High Boiler Steam Pressure as well as O2 and furnace temperature.
In boilers, economizers are heat exchange devices that heat fluids, usually water, up to but not normally beyond the boiling point of that fluid. Economizers are so named because they can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler, thereby recovering more useful enthalpy and improving the boiler's efficiency. They are a device fitted to a boiler which saves energy by using the exhaust gases from the boiler to preheat the cold water used to fill it (the feed water).
Combustion is a process which needs constant air supply for its survival, but as we move up the earth i.e. at higher altitudes, things aren’t the same as they used to be at sea level. Due to decreased air density at higher altitude, it will consume the same volume of air but will not consume the same mass of air.
This results in less fuel consumption & less steam generation rate. Due to the reduction of mass flow of gases through tubes of a steam boiler, convective heat transf...
Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen (anaerobically), primarily consisting of methane and carbon dioxide. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas is a renewable energy source.
Biogas is a byproduct of the decomposition of organic matter by anaerobic bacteria. Biogas is typically composed of 60% methane and 40% CO2...
According to the Wikipedia, Second-generation biofuels, also known as advanced biofuels, are fuels that can be manufactured from various types of non-food biomass. Biomass here means plant materials and animal waste used especially as a source of fuel.
Advanced biofuels are renewable fuels derived from renewable biomass that achieve a fifty percent greenhouse gas emissions reduction over conventional biofuels. The definition of advanced biofuels includes cellulosic biofuels, biomass-bas...
People assume that owning a biomass boiler is no different from owning its less environmentally friendly cousins, the oil and gas boilers. Nothing could be further from the truth, and it is this very misconception which leads to abuse and neglect of the maintenance that a biomass boiler needs, if it is to retain its environmental and economic saving potential. This is especially true given the tendency of many installers to skimp on providing the proper support services and education to their customers.
