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.

Henan gas boiler tube leak detection device alarm Fault Henan furnace gas boiler tube leak detection device can be checked promptly internal gas boiler heating surface Henan leak case, can effectively protect other heating surface tube row, ensure the safe operation of the economic unit. 1. Symptom: (1) one side surface of the entire heating furnace tube leak detection alarm device. (2) concentration of several parts tube leak detection alarm device. 2. Analysis: (1) Henan compressed gas pipeline leak around the boiler emits different sounds. (2) sootblower valve lift Jam, steam leakage. (3) heating surface tube bank or weld leak squib. 3. Treatment: (1) contact electric inspection personnel. (2) no abnormal sound in Henan gas boiler furnace, whether near the flange of the compressed air line check alarm leak detection means has tube leaks and timely manner. (3) Check the tube near the sootblower alarm if a valve lift leakage detecting means there are leaks and timely manner. (4) such as opening hole to see the fire, obviously abnormal sound in the gas boiler furnace Henan, Henan description gas boiler tube leakage indeed, organizers prepare repair. 4. precautions: (1) strengthen inspection. (2) Electric regularly cleaned and checked Henan gas boiler tube leak detection means. (3) make Henan gas boiler tube leak repairs should be tight plan.

WNS type gas fire tube horizontal 6 ton steam boiler system control principle: ①, after WNS type gas steam boiler on the power switch, click on the pump control switch open position, after boiler feed water rises to the normal position, click-burner power switch, clicking the start button, the control system power is on, the burner into the working state, according to the operation program for the controller, to be re-ignition burner fires into the combustion state, the boiler enters normal operation this stage. ②, high output level when the water level rose to a high level alarm signal indicator light, when the water level rises to the pump stops running + 25mm, the water pump when the water level falls -25mmm automatic restart, when the water level falls -50mm, outputs a low level alarm indicator light, with bell sound, and cut off the power to the controller to achieve protection shutdown, -75 mm when the water level falls, the output signal of low water level indicator light. ③, when the pressure is raised 0.73MPa, the output signal of the first indicator light overpressure, combustion conditions and off the controller circuit, the controller stops the shutdown. Output when the pressure rises above a second overpressure 0.75MPa signal issued bell sound, alarm and cut off the power supply control system implemented emergency stop. Regulating the pressure when the pressure exceeds the upper limit, the controller output signal of a small fire fire closed valve, a valve to open the small kerosene ignition burner. When the lower limit pressure drops below the regulated pressure, the controller outputs the fire signal to open fuel valve fire, the fire to burn. ④, after the failure of the burner failure occurs, the burner control valve is automatically shut down to stop the oil combustion.

August 10, 2018, Shanghai Industrial Boiler Research Institute Co., Ltd. (hereinafter referred to as the working pot), the National Boiler and Pressure Vessel Standardization Technical Committee of Professional Committee of boiler energy conservation (hereinafter referred to as the Commission) was held in Chengdu, organizational GB / T16508 "shell boilers" revision of the second meeting of the reported revision of the second meeting, the main author of this standard, pot capacity standard Committee appointed sub-standard boiler, the special committee secretariat a total of 10 experts attended the meeting.

Organized by the Shanghai Institute of Industrial Boiler Co., Ltd. Deputy General Manager, committee chairman Wang Shanwu chair. He said the main author of the unit where the standard of support GB / T16508 standard revision of thanks and hope the standard revision process experts complement each other, support each other, the GB / T16508 benchmark revision as the boiler industry standardization work seriously treat, carefully modified. Amended in accordance with the basic principles of the first meeting to determine, in addition to technical support for the "Boiler Safety Technology Supervision" (referred to as "Boiler Rules"), but also take into account the needs of industrial boiler manufacturing enterprises, between consideration and GB / T16507 harmonization. At the same time listen to opinions, to further enrich the standard revision work force, give full play to industry leading products representative firm.

Yung pot boiler Technical Committee Standards Committee Secretary-General Zhang Rui introduced GB / T16507.1 "The first part of the water-tube boilers: General" and GB / T16507.2 "The second part of the water-tube boilers: material" revised draft of the general framework and main content.
