steam boiler

1.        Brief

The upper blowing type boiler avoids the defections of damage from scaling and part overheating of traditional side blowing burners, which will cause it impossible for the flame to completely spread, and cause the flame directly burn the water band on the opposite side formed with boiler forge and boiler hull. By installing the burner on the top of boilers, the flame will extend completely downwards with the merits of long flame and complete combustion.

The water bands are added around the burner of the upper blowing boilers, which will not only cool the fire tube of burners, but also preheat the makeup water of boiler. As the water-cooled band of burners can be dismantled, it is extremely convenient to maintain the boilers.

With vertical type tubular structure, three strokes for smoking, top arrangement for bunrers, boiler forge, and buffer plate, the effieiency of heat exchanging is enhanced.

High water capacity, high thermal efficiency , quick steam generating, suffcient steam, long working life. The high quality famous -brand combustor and pressure pump will ensure full combusting, timely water supply and low noise.

Equipped with self diagnosing computer automatic controlling system. When experiencing malfunction, the boiler will alarm with sound and light signal and indicate the cause of malfunctionm , which provides convnience for inspection and repair.

2.        Features:

◆ Top-blown boilers to avoid the past side-blown type burner flame can not be completely carried out, directly opposite the furnace washed bile, resulting in the drawbacks of non-uniform thermal stress, top-blown burner boilers will be installed in the boiler at the top, flame top Department of down and fully carried out, the flame combustion process and the full length;

◆ body manufacturinag in line with the "security technology to monitor the boiler point of order" and "General technical requirements of industrial boilers." In full compliance with the requirements of welding process, and by the rigorous testing and pressure testing, to ensure that the quality of the quality of the boiler;

◆ Vertical structure, compact and beautiful area of small, elegant shapes;

◆ Wave oven using oven gall gall bladder, both to strengthen the flue gas of the disturbance, but also increases the radiative heat transfer area; both increase the stiffness of gall furnace, but also effectively reduced the thermal stress of furnace gall; not only enhance the effect of heat transfer and promotion of fuel combustion in the furnace;

◆Boiler water capacity less steam production quickly to meet user needs;

◆Built-in drum separator device, ensure the ready availability of high quality steam;

◆More hands-hole layout, hole cleaning, convenience and to meet the maintenance needs of users;

◆Equipped with high-quality safety valve, stop valve, pressure gauge and pressure controller (Danfoss import) and other components to ensure safe and reliable operation of the boiler.

◆The rear of the flue can be installed energy-saving heat exchanger, waste heat recovery to achieve to improve the boiler efficiency.

◆After pre-purge function, to improve the working conditions of the burner, the extension of life expectancy;

◆Special insulation materials and extra-thick insulation layer to reduce surface temperature, increase the boiler thermal efficiency.

3.        Protection device

(A), function

1, patented technology, automatic sewage functions: on the water control system for real-time detection of ion concentration, when the concentration exceeds a set value, the solenoid valve automatically open sewage, sewage automatically, start the infusion of new water pumps, heating surface so that scaling is not easy.

2, the water level real-time monitoring function: equipped with electronic water level detection device, real-time monitoring of boiler water level.

3, the time set function: users can be set to stop the time from the boiler.

4, before and after outsourcing are covered in vivo, the replacement of the heating pipe maintenance operation more convenient and more efficient.

(B), the protection of boielr

1, proprietary technology, scale detection devices: the furnace once the standard scale, the system will alarm

2, leakage protection: control system to detect leakage electric heating elements will automatically cut off power supply.

3, water protection: When the boiler water and timely control circuits cut off the heating to prevent the occurrence of dry heating pipe damaged, dry warning issued at the same time the controller instructions.

4, power protection function abnormalities: an immediate cessation of operation of the boiler.

5, overpressure protection chain: the boiler pressure exceeds a set value, and to prohibit the heater alarm.

6, over-current protection: When the boiler overload (high voltage) work, leakage circuit breaker disconnect automatically.
