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...
A condensing boiler can condense the water vapour in the flue gases and withstand the corrosive and acidic qualities of the flue gas condensate. Although most boilers can condense the flue gasses, only boilers that have heat exchangers constructed from materials able to withstand the corrosion should be used in condensing application. Condensing boilers with primary and secondary heat exchanger do not work well as they are not able to fully condense and defeat the purpose of using a condensing boiler. Also, boilers with this arrangement are prone to condensation in the primary heat exchanger at lower firing rate which can cause damage to the heat exchanger.
For a boiler to operate stably and efficiently, all links must be properly coordinated without making mistakes. For gas-fired boilers, it is necessary not only to have softened water treatment facilities, but also to carry out regular sewage discharge, which cannot be ignored.
For an industrial boiler with reasonable structural design, its thermal efficiency is relatively high, and its exhaust gas discharge temperature is relatively low, so we must carefully consider the boiler property report form when purchasing the boiler.
In the operation of gas-fired steam/hot water boiler, it need continuous water supply to ensure the water volume in the drum. Once water shortage occurs, it will cause the boiler dry burning problem, which will further result in the boiler failure and other problems.
Boiler is a piece of equipment with large energy consumption. Therefore, both boiler manufacturers and purchasers regard energy conservation as an important indicator of boiler performance. The daily energy-saving measures of the natural gas fired boiler are mainly as follows.
