DZL series biomass-fired hot water boiler

DZL series biomass-fired hot water boiler


1. The thermal efficiency of the boiler is above 77%, which is higher than the standard of General Technical Conditions for Industrial Boilers.

2. The operation realized mechanization and reduced the labor intensity of the furnace workers.

3. Quickly install the factory, after the use of the site, install the valve instrument, drum, induced draft fan, flue gas duct, energy saver, dust collector, slag machine. The coal machine and water circuit can be operated, and it has the characteristics of quick start and fire.

4. Easy installation and movement can save a lot of infrastructure investment.


On the basis of the original mature laminar combustion technology, biomass boilers have overcome the problem of organizing high-temperature swirling dynamic field in the furnace and solved the problems of coking, burning out, smoking and so on. Its burnout rate is as high as 85%-90%. Biomass fuels are widely renewable, mainly including crop straw, sawdust, sawdust, peanut shell, corncob, rice husk, branches, leaves, hay and other direct crushing or compression molding, or direct combustion of bulk fuel. Its calorific value is 3600~5100 kcal / kg. It can completely replace coal and other fuels, and its price is low, and the cost of boiler operation is greatly reduced. As the fourth largest energy source besides coal, oil and natural gas, biomass fuel has been strongly promoted and promoted by the state because of its cleanliness, environmental protection and regeneration, which conforms to the national energy and environmental protection policy.
