Product Description

    Heating supply chain grate type horizontal coal fired biomass hot water boiler

    

  Heating supply chain grate type horizontal coal fired biomass hot water  boiler has a

compact structure,The furnace wall light ,light weight beautiful appearance,high strength,

grate thick,long life and other advantages.Long steaming cycle,complete specifications,

can achieve different thermal environment,Is an advantage such as steam boiler safe and

reliable operation, better steam boilers,energy saving, environmental protection,low water

quality requirements, air distribution characteristics of reasonable,

flexible adjustment Can be adjusted accordingto the actual situation.Combustion conditions,

mechanical operation,low laborIntensity,reasonable structure,strong power, It has the following

advantages: high degree of automation, high thermal efficiency, equipped with  dust  removal

equipment to   reduce   environmental  pollution.  verticalCoal-fired energysaving steam boiler

DZL4t,DZL8t,DZL10t,  widely used in hospitals, universities,  hotels, supermarkets,  garment

factories paper  mills,  food processing  plants and  so  on. Industrial  and  mining enterprises,

organs,schools and occupational services.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

1. The use of circular tube plate and threaded pipe composed of the drum, the drum made

of quasi-steel quasi-elastic structure, the removal of the tube plate area of the pull, reducing

the boiler stress. Tube plate within the plate back from the two back to solve the problem of

tube plate crack.

2. Boiler feed water using the spray device, so that the number of water into the decline of

several times, thereby greatly improving the speed of the riser to ensure the safety of water

cycle to solve the single pot pot of water and fire tube boiler water supply reasons.

3. The furnace body is arranged on both sides of the convection tube and is heated by the

convection tube bundle so that the intake air temperature of the exhaust pipe is greatly

reduced (not less than 700 degrees). O Front tube sheet prevents cracks.

4. Efficient heat transfer screw pipe use, get enhanced heat transfer effect, to achieve

the boiler heating, improve the characteristics of fast, improve the boiler thermal efficiency.

5. Compact structure, compared with the same type of boiler, small size, saving boiler room

infrastructure investment.

6. Stable operation, adjust the intensity, there is sufficient 110% overload capacity.

Fuel.

Anthracite class II ,biomass fuel

 

1. Biomass pellets fuel calorific value, calorific value of 3900~4800 kcal /kg or so, after carbonization of heat

    up to 7000 - 8 million card /kg.

2. Biomass fuel particles of high purity, without other heat generating debris, the carbon content of 75 - 85%

    3 - 6% ash, water content of 1 - 3%,  absolutely  free of coal gangue, stone and other  impurities without

    heating instead of heat consumption, it will directly reduce costs for enterprises.

3.The biomass pellet fuel does not contain parathion, so it does not corrode the boiler, and can prolong the

    service life of the boiler, and the enterprise will benefit greatly.

4. Because the biomass pellet fuel without parathion, does not produce sulfur dioxide and P2O5 combustion

    thus it will not lead to acid rain, won't pollute the atmosphere and environment.

5.The biomass pellet fuel is clean, sanitary, convenient for feeding, reducing the labor intensity of workers,

   greatly improving the labor environment, and enterprises will reduce the cost of labor.

6.After the biomass pellet fuel burns, the ash ballast is very few, greatly reduces the place where piles up

   The coal ballast, reduces the mucking expense.

7. Biomass fuel ash, whcih is recyclable,after combustion is high grade quality organic potash.
