Hot selling automatic industrial biomass boiler and wood chip steam boiler replacing coal boiler
Introduction:
1. For the users of industrial biomass boiler, it not only reduce costs, but also reduce environmental pollution. Straw fuel is a kind of biofuel. It uses straw fuel pellet machine to make sawdust, corn stover, peanut shell, straw, cotton stalk, branch, edible fungus waste and cow dung into high-density flammable high-quality granules.
2. Biomass combustion boilers are treated as “waste”, which has become a new direction for carbon zero emission and environmental protection. It is understood that biomass fuel boilers are designed for waste in various processing industries. The main fuels include waste wood, rice husks and corn cobs.
3. Biomass fuel boilers are widely concerned because they can treat waste as well as reduce fuel costs, zero carbon emissions, and generate environmentally friendly new energy.
Biomass boilers have the following advantages:
1. Wide range of uses. The boiler can cook, boil water and bath while heating;
2. Super conversion system. Start heat transfer temperature is low, heat transfer speed is fast;
3. Low installation cost, heating safety: equipment is universal, does not change the original heating equipment, pipes, radiators are common, use water circulation to achieve a wide range of heating materials, never exhausted, It can be taken anywhere (such as: chaff, corn stalk, rice straw, wheat);
4. Safe and environmentally friendly, work pressure is small, the use of very wide.
Features
1. According to the type of fuel given, the current internationally leading biomass fuel feeding technology is used.
Due to its low calorific value and low density, biofuels make the feeding system a key technology for bio-based direct-fired boilers. The feeding system introduced by company is highly automated, easy to use and has good reliability. In the conveying system, there is a fireproof, explosion-proof, anti-self-ignition, anti-blocking system, and a fire water device is provided, which has high safety.
2. A good material circulation loop is established inside the boiler, the fuel is fully mixed, the furnace temperature is uniform, the fuel combustion efficiency is high, the fly ash has a very low carbon content, and the air pollution is small;
3. A variety of technologies are used in the boiler design process to effectively avoid boiler ash and coking, so that the boiler has strong continuous operation capability;
4. In the boiler design process, the corrosion problem caused by biomass fuel such as straw is well solved, which greatly prolongs the service life of the equipment.
The working diagram about biomass boiler is below:
The comparsion and analysis of common fuels based on 1 ton steam boiler is list below.
According to the paraments in the table, it is obviously that overall performance of sawdust, straw, rice husk and biomass fuel is very high. So the biomass steam boiler is a nice choice for your factory.
