Main Features of screw pipe 3-pass furnace steam generator coal boiler

1. Feeding fuel with 3 types : hydraulic drive, manual and chain transmission.
2. Reasonable shape: using thermal insulation materials and advanced color plate for packing. Heat preservation and heat insulation.
3. Simply operation: All data have intuitive display on the boiler,just only see the gauge according to the requirement.
4. Energy saving : rational structure, USES the adiabatic combustion, high efficiency, energy saving, fuel costs.
5. Saving investment: Without ID and FD fan, saving electricity, packing type boiler,so installation is convenient.

Machine Parts

Name: Chain Grate

Brand: Sitong

Original: China

The scale chain grate boiler could resist the temperature as high as 1200℃, long working life. It has a low coal leakage because of the small gap. High automatic degree, decrease labor cost. Convenient for maintenance, it could be done without boiler shut down.

Main Features

Name: Economizer
Brand: Sitong
Original: China
Economizer is the boiler tail flue in the boiler feed water heated to the steam pressure under the saturated water heating surface, because it absorbs relatively low temperature flue gas, reducing the smoke exhaust gas temperature, saving energy, improve the efficiency.

Machine Parts

Name: Threaded Smoke Pipe
Brand: Sitong
Original: China
The boiler use spirally corrugated tube, the thermal transfer efficiency is high. The texture of it is 20# steel, it belongs to low-carbon steel, has high tenacity.

FAQ of screw pipe 3-pass furnace steam generator coal boiler

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 difference between DZL and SZL with the same capacity?
DZL
1. Usually for the boiler with capacity lower than 10Ton
2. Easy for transportation
3. Lower request on water quality
4. Low boiler room construction charges
5. Low requirement on water quality
SZL
1. Usually suitable for bigger capacity boiler
2. Good water circulation, small water volume
3. Warm up faster, higher steam quality
4. Higher request on water quality
5. Higher thermal efficiency
3. 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.
4. The combustion space of horizontal is big, fuel can be burned completed.
5. The thermal efficiency is higher than the vertical boiler,
6. Horizontal type: less thermal loss, stronger output, and higher steam quality.
4. 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%
