4000 Kg/H Coal Fired Industrial Steam Boilers For Carbonated Beverage Production

Product Specification

4000 kg/h coal fired industrial steam boilers for carbonated beverage production line

DZH type steam boiler is a kind of horizontal three return water - fire tube boiler.Rows of water wall tubes are arranged on the left and right sides of the furnace, and two groups of tubes are arranged in the drum to form two return trips. The heating surface of this type of boiler is sufficient and the economizer of the heating surface at the end is equipped., and equipped with drum, induced draft fan to achieve mechanical ventilation.Layered combustion.The coal has wide adaptability and good smoke elimination effect.Equipping with high efficiency cyclone dust collector, the concentration of smoke and dust discharge can meet the environmental protection requirements of the second class area.The smoke passes through the upper combustion chamber of the rear arch, from the combustion chamber upward through the rear shed tube smoke chamber into the first tube bundle to the front smoke box, and then from the front smoke box into the second bundle to the rear smoke box, through the induced draft fan pumping into the flue, dust collector and chimney, and finally discharged to the atmosphere.The boiler automation level is high, the boiler feed water automatic regulation, high and low water level alarm, low water level interlock protection, lead, fan interlock protection.Complete supporting auxiliaries.

Boiler Structure 

Combustion process:

The fuel enters the furnace and burns on the grate. The flue gas from the production enters the convection tube bundle on both wings along the bottom of the boiler barrel through the smoke outlet on the middle partition wall, enters the threaded smoke pipe through the front smoke box, passes through the dust collector, and is pumped and discharged into the atmosphere through the chimney by the induced draft fan.

Technical features

(1) The pot barrel is composed of arch tube plate and threaded smoke pipe, so that the pot barrel is changed from a quasi-rigid body to a quasi-elastic body structure, and the stretch parts in the tube-plate area are eliminated to reduce the stress.The smoke pipe in the tube plate is changed from two return journey to single return journey, which solves the problem of crack in the tube plate.

(2) The bottom of the pot is arranged with an ascending pipe row, which eliminates the stagnant area at the bottom of the pot and makes the mud residue not easy to deposit. The high temperature area of the pot can be well cooled to prevent the bottom bulge of the pot.

(3) High efficiency heat transfer threaded smoke pipe is adopted to enhance the heat transfer effect and achieve the characteristics of boiler heating up and rapid pressure boost, thus improving the thermal efficiency of the boiler.

(4) Compact structure, compared with the same type of boiler, the shape size is small, save investment in boiler house infrastructure.

(5) Stable operation, convenient adjustment and sufficient output.

(6) The threaded smoke pipe is used to enhance the heat transfer, which improves the heat transfer coefficient and thermal efficiency, because the smoke has a disturbance effect in the pipe.Smoke tube is not easy to accumulate ash, play the role of cleaning.

(7) The eight-character wall in the furnace and the smoke window at the exit have a certain dust-lowering effect.The original dust emission concentration of the boiler is controlled below the standard to ensure that the soot emission of the boiler meets the national environmental protection regulations.

(8) The unique double-layer secondary air design improves the ignition condition of biomass fuel, adopts the independent air chamber, achieves the reasonable distribution of wind, forms an aerodynamic field favorable to combustion in the furnace, and makes the combustion temperature and combustion efficiency high.

Application for biomass steam boiler

Wood fired steam boiler is suitable for painting room, drying box, drying tower painting line and other purposes.It is especially suitable for central heating in urban residential areas, industrial production, enterprises and institutions, schools, hotels, bath centers and other places where heating, hot water and steam are needed.
