Performance characteristics of hot water boiler:
1. The flue gas process adopts the form of three-pass, symmetrical
wet back structure, the furnace bladder is a corrugated bladder,
the radiation heating area is large, and can eliminate the thermal
stress of the furnace, the furnace bladder is a centrally symmetric
structure, and the convection section smoke pipe adopts threaded
pipe or Light pipes to optimize heat transfer.
2. This hot water boiler adopts advanced burners, firepower
controllers, and flame monitoring, automatic purge and flameout
protection function, the harmful components in the flue gas are
lower than the national standard (No≤150mg/m3), which is an
environmentally friendly product.
3. Optional advanced touch screen + PLC controller, digital
monitoring system, with timing control work record, leak detection
alarm, pressure protection, temperature control, water shortage
protection and other functions, and can add factory timing lock,
can reserve host computer communication The interface is now
integrated control.
4. Perfect shape design, unique structure, bright appearance,
elegant color, fashionable and value-for-money.
5.100mm aluminum silicate insulation felt + mirror reflective glass
wool insulation, covered with 0.9mm outer skin, beautiful and
generous.
6. boiler condenser is added at the end of the flue, and the
thermal efficiency can reach 98%.
