The dzl series biomass steam boilers are fire tube boiler in which hot flue gases are inside the tubes and water is surrounding the tubes. Thermal efficiency up to 89% and higher because of an optimized heating surface and the optional supply of economizers. The wide boiler heating surfaces enable a better heat exchange. A bigger water volume gives to the boiler a better steam supply flexibility and stability of the steam pressure and water level.
Rated steam capacity: 2-10 ton
Fuel type: biomass pellets, palm shell, rice husk, bagasse
Application: food factory, palm oil factory, sugar factory, paper and pulp mill, refinery, etc.
Method of water circulation: natural circulation
Furnace position: internally fired
Boiler Mobility: Stationary(The boiler is fixed at one location and cannot be transported easily it is known as stationary boiler)
Safety valves: The function of the valve is to blow off the steam when the pressure of the steam in the boiler exceeds the working pressure
Water level Indicator: Its function is to indicate level of water, its upper and open in steam space and lower and opens to water space
Pressure gauge: It is for indicating the pressure of steam in a boiler
Steam stop valve: It stops or allows the flow of steam from the boiler to the steam pipe.
Feed check valve: It allows or stops the supply of water to the boiler
Blow off cock: It is for removal of sediment periodically collected at the bottom of the boiler
Man hole: It is provided in opening from which a man can enter in a boiler for cleaning
Fusible plug: Its function is to extinguish fire in the furnace of a boiler when the water level in the boiler fails to an unsafe extent thereby preventing the explosion which may takes place furnace plate
Economizers: Using economizer some of the heat recovered
Air pre-heaters: Air pre-heaters is installed between the economizer and the chimney and it abstracts heat from the five gases and transfers to air a portion of the heat that otherwise could pass up the chimney to waste.
Super heaters: Steam consumption is reduced with the use of superheated super heater heats the steam produced also production in condensation losses takes place.
Feed pumps: It is used to pump the water from storage to boiler.
Dust collector: The boiler dust collector refers to the equipment that separates dust from flue gas. It is to remove particulate fumes from boiler fuel and combustion exhaust gas
Injectors: It is also used to pump the water with for to the boiler.
