It is contemplated that inhibiting scale to generate, reducing corrosion of piping problem, complete machine parallel-adder settle-out time prolongs significantly compared with plain cylindrical furnace when design
Long, maintenance cost reduces.Complete machine uses modularization framework, and mechanism is simple, and maintenance is convenient.
(2) support multi-machine interaction and clustered control: the control of whole set equipment design size long 1600mm, wide 600 ~ 800mm,
Within high 2000mm, separate unit per hour steam quantum of output in 1-2 steam ton range.Using 50 tons of reclaim paper papermaking lines as reference, need
7 ~ 9 such equipment are wanted, then can be directed to mating one of each drying cylinder of papermaking line, realize that gas supply is installed in drying cylinder side nearby；
It by more steam generators and can also connect to generate bigger steam and export.Systems control division sets up separately in respect of RS485 and RJ45
Ethernet communication interface can be by communication modes by more when multimachine, which is combined, to be supplied to an equipment (such as above-mentioned paper machine example)
Steam generator and gas equipment master control system are connected by network mode, according to the technique of each process of gas equipment
It is required that or gas consumption how much realize flexible online control.Such as: certain drying cylinder (such as above-mentioned paper machine example) needs higher drying speed
Degree, when not changing the output of corresponding steam generator, appropriate amendment increases the steam output of forward-backward correlation drying cylinder, reaches
To final effect；Or complete machine linear speed tunes up or slow down (such as paper machine thread-changing) and can be synchronized by all steam generators of network-control
It is turned up or reduces steam output.

Steam pressure can discharge rapidly, danger caused by accumulating there is no heat accumulative and residual pressure.Simultaneity factor is using maturation
The problems such as low pressure medium frequency induction power supply, there is no electromagnetic radiation, interference.
(4) economical and energy saving: complete machine uses multinomial energy conservation measure such as flashed vapour utilization and recycle, heat recovery technology, same defeated
Heat (referring to boiler) energy consumption is few out.Electromagnetism heater high conversion efficiency, speed are fast simultaneously, using a variety of energy-saving and frequency-variables
Component makes complete machine itself, and low energy consumption.Maintenance output need to be only generated after equipment operation, there is no conveying headroom loss.Control
Fast response time processed does not need preheating or cooling, reduces idling consumption.Condensing hot air furnace is used again, reduces urban water demand.
(5) environmentally friendly: complete machine is powered using standard power frequency electric, and common softened water supplies water.It is main to generate steam and discharge less
Condensed water is measured, problem of environmental pollution is not present.Using versatile material, there is no at material mostly in complete machine manufacture and installation process
