Commercial Gas Fired Wet Back Steam Boiler in Da Nang
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.
In October 2016, my company and the China Dunhuang International Hotel signed a ZWNSL2.1-1.0 / W-Y.Q vacuum condensing gas hot water boiler to provide heating and hot water for the hotel. The boiler implementing the response to the national policy of environmental protection requirements and local environmental protection departments on a series of low nitrogen emission standard boiler requirements, in terms of design, manufacture, installation and other sectors have strict checks to ensure that the boiler safe and stable operation.
Gas-fired commercial fired wet back steam boiler in da nang FAQ boiler for your boiler sorted out 30 common problems and solutions, do not forget to share a small partner after learning finished oh. 6, the main factors which influence the rate of wear of? ① flue gas, the concentration of the surface shape of the particle size and hardness ② ③ material in the flue gas flow rate of the material is worn element, the direction of relative movement of material with the hardness of the wear element ④ greatest influence It is the speed of the airflow, proportional to the cube of wear and speed. 7, how to control the bed temperature between 850-950? ① ash does not melt at the temperature, thereby reducing the risk of slag settle ② The temperature nitrogen having a high desulfurization efficiency ③ combustion gases at this temperature ④ less of the gas at this temperature the coal is not an alkali metal sublimation can be reduced slagging of the heating surface. 8, why should the torch boiler? Soda boiler system equipment such as part of desuperheating water, startup bypass, superheater, reheater piping system, due to the structure, material, arrangement, etc. are not suitable for chemical cleaning, so newly installed inside the boiler required physically remove remaining debris before officially put into operation, it is produced using the steam oven of the present systems and devices torch soda process. 9, common maintenance method, which has several boiler (1) Wet protection: with ammonia, liquid ammonia method, a method to maintain water pressure, steam heating method, a method of alkali, trisodium phosphate, and a mixed solution of nitrite Protection Act;? (2) dry protection: drying method (with pressure drainage) and desiccant process. 10, what? (1) steam with water vapor causes of quality deterioration (steam pollution). Boiler feed water containing impurities. After heating into the boiler feedwater into steam, most of the impurities are also transferred to the boiler water, so many times the cycle, increasing the impurity concentration of boiler water. Boiler water containing a high concentration of impurities is carried with the steam is called saturated steam water vapor with a machine called water carried, the first reason is contaminated steam. (2) steam soluble salt. The boiler at a higher operating pressure steam dissolves some salts, referred to as selective carry steam soluble salt, which is the second reason steam contamination.
Gas commercial fired wet back steam boiler in da nang Gas steam boiler faults and fix problems economizer heat what is the reason? Acoustic cleaners using main function is used to remove fouling the heating surface of each gas-fired boiler, has the advantage of traditional mechanical cleaning, sootblowing steam and ash ball, etc. can not be compared, in the electric power, petrochemical, and other fIELD used widely, part of the solution superheater boiler system, the new non-contact heating surface cleaning method of cleaning economizer, an air preheater and a waste heat boiler, a heat pipe heat exchanger. Gas cylinder steam boiler Branch Church of the trap in what place? Gas-fired steam boiler cylinders trap points at the bottom of the cylinder, which is a standard valve, are design specifications. Horizontal Horizontal gas steam boiler and gas steam boiler how much money each one, with a good restaurant to what kind of horizontal gas steam boiler, the price is no way to determine because the size depends on your power ! And because different manufacturers offer different quality and technology will be different. So, boiler safety accessories must be required to regularly check. Gas-fired steam boiler itself flawed: When the pressure component aging, strength weakened, or leakage, corrosion, deformation, scale and other defects, not timely maintenance in order to eliminate hidden dangers, but let boiler "sick to run," and so on. Therefore, the boiler must be regularly tested according to national requirements. Poor management, fireman officer is not responsible or low levels, lead to misuse. So fireman must obtain operating permits required. Four gas steam boiler safety accessories limit how often examined once? Four steam boiler safety accessories means that safety valve, pressure gauge, water level gauge, thermometer. General safety valve check once a year. General pressure gauge check at least once every six months. Water level should be washed once per shift. After checking with the thermometer mounted least once a year. How to change the temperature of the steam boiler the steam pressure of the gas changes.
