Wuhan Port District Social Welfare Institute (apartments for the elderly) is invested by the government pension services, with a total construction area of ​​38,000 square meters, 532 beds, mainly adopt destitute persons, social support on behalf of the elderly. Hope to provide welfare to the elderly year-round 24-hour hot water, the original boiler equipment can not meet this demand, therefore, require additional purchase orphanage combined fired hot water boiler dealer in africa. After much investigation, in cooperation with the welfare determined fast boiler, provides three integrally condensing gas hot water boiler (WNS1.4-1.0 / 95/70-Y.Q) by a fast boiler.

2. szs series oil/gas boiler

The SZS is a modern D-type water tube boiler design, with gas tight membrane wall construction for all furnace walls including the front wall to maximize heat transfer. Tube manipulations for burner and man door penetration maintains optimum circulation. Two stage separation within the steam drum ensures high quality steam.

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 the national standard of water quality standard, the water quality index of combined fired hot water boiler dealer in africa stipulates that the total hardness of water supply for chemical treatment outside furnace is less than 0.6 mmol / L. In recent years, in order to reduce the operating cost of heating units, some hot water gas-fired steam boilers have been overloaded due to the use of class Ⅲ bituminous coal as fuel instead of class Ⅱ bituminous coal designed to replace the designed type Ⅱ bituminous coal. During the maintenance in summer, it is found that the overloading boiler water wall tube fouling problem is more prominent, some boilers even occur tube burst accident. Why is heating hot water boiler overloaded, scale and even burst tube? Because the calorific value of class Ⅲ bituminous coal is higher, the type Ⅲ bituminous coal of the same weight is burned instead of the designed class Ⅱ bituminous coal. Bituminous coal increases the circulation of boiler riser is not absolute equilibrium, the geometric difference of riser and the heat load are different, so there is inevitably the deviation of flow rate between the risers. Due to the overloading operation of the boiler, some riser tubes are easy to overheat boiling because the flow rate is small, and the wall temperature is higher than the designed wall temperature, so that the scale and even the tube burst are easy to occur. How to prevent the boiler from scaling when overloaded? The heating hot water boiler operates under overload because of the scaling after the superheated boiling. Steam is produced in the process of superheated boiling. The water quality requirement of gas steam boiler is less than 0.03 mmol / L, which is much lower than that of hot water boiler. Water quality requirements. Based on the above reasons, the feed water hardness of heating hot water boiler is reduced, and the scaling phenomenon is eliminated by reducing 0.6mmol/L to 0.03mmol/L.
