wood biomass coal fired hot water tube steam boiler for Laundry

Introduction

coal fired steam boiler dopts light chain belt grate, it has high automatization, strong dust removing function, less environmental pollution and it has good comprehensive economic and technical indicators . It has lots of advantages such as quick installation, saving time and material, compact structure, small occupied area, high reliability, high thermal efficiency and strong overload capacity and so on.

Technical Parameters

Performance characteristics

Extremely flecible and simple installation.Just place the boiler on the foundation.

• Heating area is the closely-aligned round coils.Heating area is arranged sufficiently to reduce the surface heat load of pipe and handle the heat transfer oil safely.

• Size of hearth matches the combustion flame.Use the barotropic combustion to increase the radiation heating efficiency.

• Compact boiler saves the space of boiler room greatly.

• Air preheater is mounted at the tail of large boiler to improve the efficency.

Advantage 

1.With efficient special designed spirally corrugated tube----Making boiler’s actual capacity is 10-15% higher than name plate capacity
2.It uses new hearth with large volume, ----Improving boiler efficiency,reducing fuel consumption in largely
3. Most advanced technology for arch ---- Boiler's hearth has a dust separation reversing chamber,it ensures that the original dust discharge concentration is lower,protection enviroment
4.Optimally designed steam separator ----facilitates vapour gravity separation,and makes the steam humidity lower than 1%, obviously lower than international standard of 4%;

Applicable fuels

This is Applied for Textile Mill,Food and Beverage,Chemical,Medicine,Light Industry,Rubber,Printing and Dyeing Plant,Paper Mill,Wood Processing,Garment and Laundry etc.

FAQ 

1.What are the spare parts for DZL/SZL series coal/biomass fired boiler?

Generally, the spare parts are instrumentation valve, grate plate, gasket, etc.

2.What are the differences between vertical type boiler and horizontal type boiler with the same capacity?
1.Structure of vertical boiler is compact, occupy a limited area,
2.Convenient on installation and removal.
3.Low cost and investment on capital construction. Steam exhausted fast and sufficient.
1.The combustion space of horizontal is big, fuel can be burned completed.
2.The thermal efficiency is higher than the vertical boiler,
3.Horizontal type: less thermal loss, stronger output, and higher steam quality.

3.What are the limitation (size, humidity, chemical element concentrations) of coal fuel/solid fuel/wood fuel?
Size requirement of coal:6-25mm
Size requirement of blending coal: <50mm (the coal less than 6mm should less than 30%)
Diameter of biomass particle: 6~10mm, length: 25~50mm, water content < 15%, ash content < 2%, sulphur content<0.07%, chlorinity <0.07%, nitrogen content < 0.5%

4.What is the size of furnace door and blower hopper?
Size of furnace door:
Standard elliptical furnace door:300*800*1500
Blower hopper size:
2 tons conical hopper: 1400*800*1500
4 tons conical hopper: 2200*1400*1500
