Fangkuai Boiler is a clean-up boiler equipment based on various excellent scientific and technological advancements, focusing on product development, manufacturing, and manufacturing that are more efficient, environmentally friendly, and energy saving, and meet the basic national conditions of environmental protection in China. In order to promote the rapid development of the heating furnace manufacturing industry, people-oriented, consider the specific requirements of customers in the manufacturing industry for heating furnaces in various industries.

Gas china steam boiler manufacturers which safety devices 1, real-time monitoring water: water with electronic detection devices, real-time monitoring .2 boiler water level, time setting function: the user can be freely set in combination boiler stop time from .3, leakage protection: the control system upon detection of leakage electric heating elements will automatically cut off power .4, water protection: when the time to cut off water gas boiler burner control circuit to prevent the occurrence of dry damage the burner, while the controller sends missing .5 water alarm indicator, power protection function: gas steam boiler immediately stopped .6, overpressure interlock protection: when the boiler pressure exceeds the user set value, the burner operation is prohibited and the alarm .7, pressure controller, water level alarm, safety valve, low water level alarm and other multiple security .8, and the complete gas train protection system: to provide the filter, regulator, solenoid valves and accessories such as a complete gas train to ensure that the gas .9 safety, flue gas monitoring means can automatically monitor the exhaust gas temperature of the boiler, more easily grasp the combustion boiler.

Safety precautions when using electric boilers hot water boilers has many safety precautions, especially hot water boilers, it is more to pay attention to some of the security detail during use. In operation hot water boiler must be put in line with the provisions of clothes, carefully check all parts of the boiler system, such as pressure gauge, safety valve, gas pipe fittings, water level, etc., everything is correct before continuing work. Must pay attention not to water one-handed operation, one hand and water in one hand and the door is open water steam valve, when the water column to a predetermined level, the first valving then off Watergate, this order can not be reversed, and the valving face when not to It is on the water, to prevent splash injuries face. In the boiler has been at work, surrounding someone must guard the moment the water level and pressure gauges, there can be no neglect of duty, if the night shift work, be sure to have a good rest during the day, so that when the work will not fall asleep at night, because once any carelessness, accidents will happen. And every night the boiler sewage treatment, water table should clean up once every night. For motor and other mechanical equipment have always been its inspection, if any abnormal findings, the investigation must be immediate. Weekly safety valve should be checked whether it is safe.

The main components of the boiler: boiler lot of people know, but do not always understand the boiler, even customers who have purchased the boiler is not very understanding of what are the component parts of the boiler. Today to look at a detailed analysis of boiler components which mainly consists of: 1, drum. Its role is to collection, storage, and supplementary steam feedwater purification. In water-tube boilers usually 1 to drum 2, the drum is called a steam drum (drum), referred to below water or mud drum drum. The inner drum has a uniform distribution of the feedwater tank, and the water separation means the continuous blowdown apparatus. Internal boiler drum water tube assembly and a separator and the like. The outer drum containing the main steam valve, the sub-steam valve, safety valve, air valve, water level gauge, sewage connection pipe and pressure gauges. One end of the head or top of the drum was Manhole. One end of the drum head with the open manhole bottom with periodic discharge means. In many riser and downcomer (bundle) connected to form the entire structure of the elastic member between the upper and lower drum. 2, water wall heating surface. It is disposed around the furnace radiation heating surface. Boiler tube made of φ51 × 3 ~ φ63.5 × 3.5mm in industrial boilers generally used rust, while the main heating surface of the water tube boiler. Radiation heating surface absorption of radiant heat and flame shield the furnace wall, and thus play a protective role in the furnace wall; the same time, as more endothermic, the furnace temperature can be reduced, as well as to prevent burning effect coking coal seam. 3, header. It is a collection of tubes arranged in the main element is coupled, and a dispensing action of water drawn, its location has upper header and a lower header or inlet header and the outlet header bin of. A header welded seamless steel pipe is generally greater diameter and two end caps. In recent years, some manufacturers shut spinning tube ends, substituted welded end cap, a more rational structure. 4, the convection heating surface tubes. Convection convection bank known as the drain pipe, located between the upper and lower drum, generally by a boiler φ51 × 3mm steel composition, the main heating surface of the water tube boiler. In order to sufficiently absorb heat, convection bank usually intermediate, separator trap wall consisting of a flue or turns back and forth, increasing the flow of flue gas, and smoke at high speed across tube bundles. 5, the pyrotechnic heating surface tubes. Smoke tube heating surface is the main fire tube smoke-tube boiler and a combination boilers, its role is as high temperature flue gas generated from the combustion furnace flows through the inner tube, the outer pot of water continuously on the heating tube, it gradually becomes steam (or hot water). Smoke tube is typically mounted pot shell, fixed to both ends connected to the tube plate by welding or expansion. Because of its limited number of installations of the boiler shell, plus content of the tube is easy to plug fouling, easy outer tube fouling, it is not practical for large boilers. 6, the superheater. Economizer and air preheater, which belong convection heating surface. Superheater convection superheater addition, there are radiation superheater, economizer and a preheater rest are mounted boiler backpass. Their role in the main exhaust gas temperature is further reduced, improving the thermal efficiency of the boiler.
