1. Biomass fired furnaces (boilers)-ZG Boiler manufacture Biomass fired boilers( furnaces) is more environmentally friendly than other fuels. If it's a waste product of industry, burning it avoids sending it to landfill—so it's doubly good for the planet. What is biomass? Biomass is a fashionable, fancy word that really just means plants (or other once-living things) used as fuel (especially ones grown specifically for that reason). Wood fuel gathered by people in an African country is biomass; ethanol, used to make diesel for car engines, is also biomass; and chicken manure used to fire power plants is biomass too. The great thing about biomass is that it's a kind of renewable energy: plants grow using sunlight, which they convert into chemical energy and store in their roots, shoots, and leaves. Burning biomass releases most of that energy as heat, generate electricity, and fuel our vehicles. Biomass is more environmentally friendly and sustainable than fuels such as coal for three main reasons. 1.Unlike coal (which takes many millions of years to form from plant remains), biomass can be produced very quickly and we can easily grow new plants or trees to replace the ones we cut down and burn (in other words, biomass can be genuinely sustainable). 1.Plants absorb as much carbon dioxide from the air when they grow as they release when they burn, so in theory there is no net carbon dioxide released and burning biomass does not add to the problem of global warming. (That's why biomass is sometimes called a carbon neutral form of energy.) I say "in theory" because in practice growing, harvesting, and transporting biomass may use energy and that reduces the overall environmental benefit. 3. Biomass is often simply wasted or sent to landfill. Burning something like waste wood off-cuts from a lumber yard or chicken manure from a poultry factory not only gives us energy, it also reduces the waste we'd otherwise need to dispose of. What is a biomass furnace? People tend to burn biomass in two ways. The simplest method is to use a wood-burning stove, an enclosed metal box made from something like cast iron, with opening doors at the front where the fuel is loaded up and a small smokestack called a flue to carry away carbon dioxide, smoke, steam, and so on. This generally provides heat in a single room, much like a traditional coal fire. A biomass furnace is a more sophisticated option that can heat an entire building. Unlike a wood-burning stove, a biomass furnace does the same job as a central-heating furnace (boiler) powered by natural gas, oil, or electricity: it can provide hot water and it can even power modern underfloor central heating. It's not like a dirty and labor-intensive coal-fire and doesn't require huge amounts of starting up, cleaning, or maintenance. All you have to do is load in your biomass (generally, you'd use wood pellets, wood chips, chopped logs, cereal plants, or a combination of them) and periodically (typically every 2–8 weeks, depending on the appliance) empty out the ash, which you can recycle on your compost. While wood-burning stoves have to be manually filled up with logs, biomass furnaces are often completely automated: they have a large fuel hopper on the side that automatically tops up the furnace whenever necessary. Unlike with a coal fire boiler, you don't have to mess around trying to get the fuel lit: biomass furnaces have simple, electric ignition systems that do it all for you. It's perfectly possible to run a system like this all year round.

2. Biomass boiler furnaces and wood-burning stoves are generally considered to be far more environmentally friendly than home heating systems powered by fossil fuels, but one drawback is worth bearing in mind: burning biomass is cleaner than burning coal but still produces air pollution. If you're considering buying a biomass boiler or furnace, ask about emissions (sales brochures usually mention how much dust, carbon monoxide, and oxides of nitrogen appliances produce); and be sure to find out whether there are pollution or other planning restrictions in your area before you commit yourself to an expensive purchase.
