The flue classification for a solid fuel boiler typically falls under the category of "Type B" or "Type C" flues, which are designed to handle the specific combustion gases and particulate matter produced by solid fuels like wood, coal, or biomass. These flues must comply with relevant building codes and standards to ensure proper venting and safety. Additionally, they should be constructed with materials that can withstand the corrosive effects of the flue gases and high temperatures associated with solid fuel combustion.
The correct flue classification for a solid fuel boiler connected to a brick flue is typically classified as Class 2. It is important to ensure that the flue meets the necessary building regulations and safety standards to prevent any potential hazards. Professional installation and regular maintenance are recommended to ensure the system operates safely and efficiently.
The correct flue classification for a solid fuel boiler connected to a brick flue is usually Class 1. This type of flue is designed for solid fuel appliances and provides a high level of safety and performance. It is important to ensure that the flue meets building regulations and is installed correctly by a qualified professional.
If the boiler fuel contains Sulphur (and most do) combustion products in the flue gas will include Oxides of Sulphur (SO2 and SO3). SO3 combines with water (H2O) to make Sulphuric Acid (H2SO4). If the temperature of the flue gas falls below the dew point, the combination of the acid with the moisture in the flue gas causes corrosion of the flue gas duct work. Bypassing the economiser in the early stages of a boiler start keeps the flue gas temperature above the dew point.
Economizer is an accessory of boiler that recovers the waste heat from the flue gas blown out of the boiler. Thus it actually "economizes" the operational cost or in other words, improves the efficiency of fuel utilisation in the boiler. The temperature of the flue gases ( the mixture of burnt fuel & air ) depends up on the steam pressure ( temperature more precisely ). Higher the steam pressure generated, the higher is the flue gas temperature. Economizer is a heat exchanger which exchanges heat between water ( which is fed in to the boiler ) & the flue gas. It means it increases the temperature of the feed water using the otherwise wasted heat of the flue gas. So the water entering the boiler has higher temperature compared to the one without this economizer. This higher temperature of water requires less amount of heat to generate steam so the operation becomes "economical". Similarly the economizer can also work to heat up the air entering the boiler through the flue gas heat, instead of heating the water.
Solid fuel boiler can be purchased from Nextag, eBay, Amazon. One should check with their local energy company for a better deal and service for this product.
Solid fuel flues generally last for 15 years +. Oil or gas flues are prone to build ups of acid inside the flue and therefore have a shorter life expectancy.
Solid fuel back boilers are less common due to environmental concerns. Boiler Hut provides more efficient and eco-friendly alternatives.
boiler efficiency calculation methods:Input-output methodη = Output / Input Output is defined as the heat that is absorbed by working fluid. Input is defined as the chemical heat of fuel plus the heat that is added to working fluid, air, gas and other fluid circuit in which the fluid circuit across thin layer.Heat Loss MethodHeat loss method is the method that is used to calculate the percentage amount of heat which is not useful. This method is very effective used in an attempt to find potential savings of boiler with heat balance. There are several factors act as the source of heat loss combustion. These factors will be used to calculate boiler efficiency based on heat loss method. The source of heat loss can be seen as following below:a. Heat loss due to dry flue gasHeat loss due to dry flue gas is the heat loss which is contained in dry flue gas such as CO2, O2 and N2. These gases are one of causes of heat loss in combustion process. The high temperature of flue gas coming out from boiler affect amount of heat loss.The weight and heat loss of dry flue gas of combustion of coal can be calculated as following formula:Wdfg = mCO2 + mSO2 + mO2 + mN2Eloss dfg = Wdfg x Cp x (To - Ts)Where:Wdfg = weight of dry flue gas (kg/kg coal)Eloss dfg = heat loss in dry flue gas (kJ/kg)To = temperature of dry flue gas coming out from boilerTs = temperature of surroundingby Gajanan Nalegaonkar
boiler are working on same principal but automatic and manual boiler has difference that manual boiler working at single element loop and automatic boiler work at three element loop.single loop means when fuel increase mean load increase on boiler by adjusting fuel operator has to adjust steam drum level manualy , while automatic means when load increas, fuel increase steam drum level adjust automaticaly by watching fuel consumption.

A commercial gas boiler may keep backfiring due to several reasons, including improper air-to-fuel mixture, which can lead to incomplete combustion. Additionally, issues such as a blocked flue, malfunctioning burners, or gas pressure fluctuations can contribute to backfiring. Regular maintenance and inspection are essential to identify and resolve these problems, ensuring safe and efficient boiler operation. If the issue persists, consulting a qualified technician is recommended.
