A well designed and operated biomass boiler burning fuel within the specification of the boiler should not produce any smoke, but black smoke may be produced if the fuel is too wet for the boiler. All biomass boilers produce some oxides of nitrogen (NOx), particularly nitrogen dioxide (NO2). While NOx emissions from gas boilers have been reduced significantly in recent years through the use of low NOx burners which burn at a temperature slightly below that at which NOx forms, the nature of biomass combustion, and the need to ensure the complete combustion of wood gases, means that combustion takes place at a temperature where atmospheric oxygen and nitrogen can chemically combine. The better the quality of the combustion control system on a biomass boiler, the lower the NOx emissions will be. In general, biomass boilers produce less NOx than oil boilers. Biomass boilers do not produce any oxides of sulphur (SOx).
Radiation and convection losses will vary with boiler type, size, and operating pressure. The losses are typically considered constant in BTU/hr, but become a larger percentage loss as the firing rate decreases. Boiler design factors that also impact efficiencies of the boiler are heating surface, flue gas passes, and design of the boiler and burner package.
The heating load of an industrial boiler refers to the amount of energy required to generate a certain amount of heat in a specific period, usually measured in British Thermal Units (BTUs) per hour, kilowatts (kW), or megawatts (MW). Essentially, it's the amount of energy needed to heat the water or generate steam in the boiler for industrial processes or heating purposes.
Understanding the heating load is crucial for several reasons:
Boiler Sizing: Accurately determining the heating load is e...
Black smoke in gas-fired boilers is typically an indication of incomplete combustion, where the fuel is not being burned efficiently. This can happen due to several reasons:
Poor Air-to-Fuel Ratio: The most common cause of black smoke is an improper balance between the air and fuel. Too much fuel or insufficient air leads to incomplete combustion, resulting in black smoke due to unburnt carbon particles.
Dirty or Clogged Burners: Over time, burners can become dirty or clogged, affecting the ef...
The water level of steam drum can reflect the condition between feedwater quantity and evaporation quantity of boiler. If the two parameters maintain a stable balance, the water level also remains unchanged; otherwise, the water level will rise or fall. Besides, there is also a false water level phenomenon. How do we understand the false water level?
Is the molten salt heater a boiler? ZOZEN Boiler, a professional molten salt heater manufacturer, will answer this question. Boiler refers to the closed equipment that uses various fuels, electricity or other energy sources to heat the contained liquid to a certain parameter and bear a certain pressure, and its scope is defined as a pressurized steam boiler with a volume greater than or equal to 30L; Pressurized hot water boiler with outlet water pressure greater than or equal to 0.1MPa (gauge p...
Because a certain amount of air is usually dissolved in water, with the increase of temperature, the solubility of air decreases, and the gas is gradually separates from the water in the process of water circulation, and gradually gathers together to form large bubbles and even gas columns. Gas is often produced due to the water supplement, so the boiler exhaust valve must be used to avoid damage to the system.
New energy boiler fuel is a new clean and environmentally friendly fuel product. The fuel of new energy boiler is clean, sanitary, green and environmentally-friendly. No "three wastes" such as waste gas, wastewater and waste residue are discharged in the production process. It has high oxygen content, full incineration, no black smoke, no carbon deposit, no boiler black bottom, no residual liquid or residue. The waste gas from incineration is more than 80% lower than that of LPG.
