10 ton gas fired steam boiler

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.

Recently, Dongguan City, Guangdong Province, announced the embodiment of combustion facilities out of the transformation of coal-fired boilers. Continued efforts to implement air pollution control operations, blue sky to win the battle to raise the overall urban air quality, promote the construction of beautiful Dongguan.

Program execution object: the end of 2018 or for the gas central heating has been completed and all coal-fired boilers, furnaces, stove and other combustion facilities within the region.

Remediation program goal: to complete the gas before the end of 2018 has been for central heating or combustion facilities have been built out of regional coal-fired boilers and other renovation work. among them,

1, 2018 May 31, the gas supply has been built up, or central heating coal-fired boilers and other combustion facilities within the region, incorporating the first period regulation, must be completed before the phase-out renovation work in October 2018 31

2, June 2018 period from 1 July to 31 December 2018 for gas central heating area is built up or coal-fired boilers and other combustion facilities within the scope of the regulation into the second period, to be completed by 31 December 2018 out of the transformation.

Program remediation requirements:

1, the boiler must get out of the transformation of the city of Quality and Technical Supervision issued by the migration, retirement, cancellation of certificate or change a new boiler fuel use permit after; furnace, stove eliminated after the transformation of environmental protection must apply the change.

2, central heating is completed, it must use natural gas, liquefied petroleum gas, electricity and other clean energy combustion facilities outside the area out of coal-fired boilers, etc. after the transformation continued use.

3, central heating boilers planning area must use the central heating (gas) after the completion of the heating zone, will not have the heating conditions can use natural gas, liquefied petroleum gas, electricity and other clean energy as a transition.

4, into the "scattered pollution", high pollution and high emissions from industrial boilers and enterprise-wide to be eliminated.

5, for failure to complete boiler or eliminated within the rectification period, the Municipal Environmental Protection Bureau in accordance with the requirements of relevant laws and regulations and strict enforcement of its Municipal Quality Supervision Bureau will be canceled.

How to choose a 10 ton fired steam boiler heat exchanger? Steam boiler heat exchangers are generally divided into two categories, one is a direct contact heat exchanger, and the other is an indirect heat exchanger. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. They are used to recover flue gas heat, to achieve energy saving effect of the separation device. In general, conventional steam boiler can be increased by a simple transformation of energy-saving effects, such as increased waste heat recovery installation, which is energy-efficient steam boilers advantage. To promote energy saving is largely the cause of the country, to create more profits for the company, cost savings. Choose a good heat exchanger is one way to achieve energy efficiency goals. Direct contact heat exchanger is a steam boiler with heat recovery and a high ability to remove pollutants in flue gas, but acidic water quality, not easy to use in hot water heating boiler. The so-called indirect heat exchanger, thermal energy means that we recovered from the condensed-called flue gas. Today, more and more people choose to use the steam boiler, the proportion of the market is also increasing. Such steam boiler flue gas discharged contains a large amount of steam, by condensation and release large amounts of latent heat of vaporization. Coal-fired boiler efficiency is much higher than coal-fired boilers. This boiler has a good effect on the selection of the indirect heat exchanger.

Why condensing boiler sales will increase every year? Under the influence of the modern concept of energy saving in the purchase of products like heating is more popular in condensing boilers, statistics confirmed that showed sales rising year by year in the state during the years of research and development come out of condensing boilers. So why year after year of rising sales of a full range of condensing boilers do? We will be analyzing the reasons for the rise in sales of condensing boilers below. One reason, can save heating costs are well known in the modern condensing boiler has not yet come before people in many parts of the device only by means of conventional boiler when heating is influenced by the principle of cause conventional boilers spend a lot of energy to release some heat . But they have very different condensing boilers and conventional boilers in the design and working principle of the above, the use of modern release can save heating costs on top of a relatively large amount of heat condensing boiler to a certain extent. Two reasons, can reduce the frequency of replacement of modern heating equipment currently on the market of raw materials existing ordinary boiler product is mostly copper, after long-term use of corrosion and thus vulnerable to a series of failures to be replaced. Condensing boilers produced material was stainless steel, even if the contact during operation of the steam does not affect their quality will be able to make virtually modern replacement frequency heating apparatus is controlled. Class three reasons, the release of a very small amount of nitrogen oxides during the operation most of the conventional type boiler in operation of heating equipment are required to coal-derived material as a raw material, coal or the like at the time of combustion of the material will release a large ships harm air quality material composition. While condensing boiler during operation of the steam is produced after combustion of natural gas as a raw material, and therefore the operation at the time of release of the content of nitrogen oxides is much lower than a predetermined standard. Analysis of the reasons condensing boiler sales rising year by year made temporarily come to an end. Through the above three reasons we can have some understanding of the advantages of using credible condensing boiler from the side, I believe that with these advantages condensing boiler different from the ordinary boiler heating equipment will continue to grow in future sales.
