DHS(DC) Skid-Mounted Condensing Gas Steam Boiler
1. Integrated FIR low-nitrogen burner technology, corner tube technology and plate and shell deep condensation technology.
2. Unique “ultra-low nitrogen internal circulation technology”, with gas consumption per ton of steam ≤ 74.5 Nm³.
3.Deep condensation, with flue gas temperature ≤ 48°C (in the condition of no condensate water recovery);
4. Multi-unit group control to avoid “large horse pulling small cart”
5. Small in Size, flexible to be mounted.
Description
Product Name: Skid-Mounted Condensing Gas Steam Boiler
Product Model: DHS(DC) Series
HS Code: 84021900
Manufacturing Standards: ASME/EU/GB
Packing: Main body in nude packing, auxiliaries in steel frames for bulk vessel.
Application Range: 4t/h≤D≤6t/h; P≤3.82Mpa
Feature – More Energy Saving
1. Deep condensation, smoke temperature ≤ 48℃. By comprehensively applying various enhanced heat exchange technologies and making full use of flue gas condensation heat, thermal efficiency of boiler is up to 103%, which can save 4-6 m3 natural gas per ton of steam than common condensing boiler, more energy saving.
2. Large boiler drum space & unique design of steam drum internals provides better steam-water separation effect with steam dryness achieving ≥ 99%. Low pipe losses with high energy efficiency.
3. Fast steam generation (Steam can be generated in 5 minutes from cold state). Multiple boilers can be connected in parallel with a wide load adjustment range and more energy saving operation.
