china cheap natural gas fired steam boiler

At present several common boiler energy-saving technologies: usually for boiler manufacturers, it means that you are saving boiler to maximize the interests of customers, providing customers with unlimited fuel savings, the electricity consumption, water consumption and so on. But the wide range of energy-saving, does not refer to an aspect of optimization can save energy boilers, here's a look now common boiler energy-saving technologies: 1 furnace arch. Industrial boiler furnace arch is very important. Arch role is to cause the furnace hearth and the organization of the mixed gas and the radiation hot flue gas flow, ignition and combustion of the fuel in a timely manner. At present, the actual amount of industrial china cheap fired steam boiler with its rated load often do not match, the use of coal varies widely, but often with the design coal are quite different, so in actual use, often as necessary for the furnace arch modified to meet the needs of coals. Heteroaryl coal used by the inferior design coal, the boiler furnace exit gas temperature occurs is low (about 700 degrees), lower than 200 degrees design.

In mid-June, Yingtan City, Jiangxi Province issued a "Yingtan City People's Government Office on the issuance of three-year action plan to win Yingtan City Blue Sky Battle (2018-2020 years)", Yingtan City Market Supervisory Authority proposed by file stringent targets execution, to carry out a three-year coal-fired boiler special work within the city.

The special rectification, on the basis of thorough investigations within the jurisdiction of coal-fired boilers, the high standard, high-efficiency coal-fired boilers to complete the rectification work to ensure that by the end of 2018 as required successfully completed. 10 out of 21 local stations steam tons / hour and coal-fired boilers and started to build the city and out of the city of 35 tons of steam coal-fired boilers of work; involving the transformation of coal-fired boilers, technical testing organizations should strictly follow the relevant safety technical specifications strict technical clearance, and the overdue completion of the rectification of the enterprise be severely punished according to relevant laws and regulations.

Up to now, the council investigation of coal-fired boiler unit 16, a total of 21 Mopai boiler units, 12 units have been removed, and the rest are in the boiler rectification. Next, the council will further strengthen the regulation of coal-fired boiler follow-up supervision, to ensure that regulation effect.

Pressure boilers Products of the non-pressure hot water boiler, also called pressure boilers, boiler usually refers to the top does not bear the water column static pressure of the heating system. That is quite an open hot water tank. Meaning pressure boiler: boiler body opening to the atmosphere. In any conditions, the boiler at the water line are zero gauge pressure boiler. Pressure boilers Model consists of three parts, connected by a hyphen between the parts. Categories: pressure hot water boiler is mainly classified by fuel can be divided into CLDR (CWDR) often piezoelectric hot water boiler, CLHS-YQ (CWNS-YQ) pressure fuel (gas) hot water boilers, pressure coal-fired hot water boilers. Model: The first part of the model by atmospheric pressure boiler code, pot-type code, combustion equipment code, the rated thermal power four sections. Boiler pressure is represented by C code example: CLSG0.35; 95/70; W12 represents a vertical pipe fixed grate boiler pressure, the rated thermal power of 0.35 mW, rated outlet water temperature was 95 deg.] C, the nominal temperature of the water inlet. 70 ℃, burning anthracite class I, a second design of the boiler. Product Structure: The overall structure of pressure boilers and boiler auxiliary equipment including two parts. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Boiler body is in two main parts and drum furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. Furnace design needs to fully consider the characteristics of the fuel used. Each boiler should be fueled with the original design of the fuel. Boilers running economy and reliability are likely to vary greatly reduced when using the characteristics of fuel combustion. And the natural circulation drum is repeatedly forced circulation boiler receiving feedwater to the economizer, the coupling cycle and supplying saturated steam superheater cylindrical vessel. Simplified drum made from high quality steel plate, is one of the heaviest components of the boiler. Safety knowledge; boiler is a high-temperature, high-pressure thermal equipment, is one of special equipment, widely used in government agencies, public companies and all walks of life, are dangerous and special equipment. Event of an accident involving public safety, it will cause huge losses to the state and people's lives and property. For public safety, people's lives and property safety, according to the State Council, "Regulations on Safety Supervision of Special Equipment", the boiler should use full attention the following matters: 1, should be accompanied by safety technical specifications of the factory boiler design documents, product quality certification, safety and the use and maintenance instructions, supervision and inspection certificate (safety supervision, inspection and performance certificate). 2, boiler installation, maintenance, alteration. Engaged in the installation of the boiler, maintenance, renovation of the unit shall obtain special equipment installation and maintenance certificates issued by the Provincial Quality and Technical Supervision, before engaging in the boiler installation, maintenance, alteration. Construction unit before construction will be prepared for installation, maintenance, alteration in writing inform the special equipment safety supervision and management department of the municipality or district, and will start informing sent to the local county level Quality and Technical Supervision for the record, told immediately after construction. 3, inspection of boiler installation, maintenance, transformation. After construction, the construction unit To State Quality and Technical Supervision of Special Equipment Inspection and hydrostatic testing of the boiler installation supervisory inspection declaration. After passing by the State Quality and Technical Supervision, State Special Equipment Inspection, County of Quality and Technical Supervision involved in overall acceptance. 4, registration boiler. After the boiler inspection, the use of units must be in accordance with the "special equipment registration and use of management rules", fill "boiler (census) Registration Form", the State Quality and Technical Supervision to register and obtain a "registration certificate to use special equipment safety . " 5, operation of the boiler. Boiler operation must be performed by trained and qualified to obtain "special equipment operator certificate" certified personnel to operate, must strictly abide by the rules and eight systems, six record. 6, check the boiler. Periodic inspection of boiler once a year, not be used without safety periodic inspection of boilers. Safety accessories safety valve of the boiler regular inspection once a year, pressure gauge biannually verified, may not be used without the periodic inspection of the safety accessories. 7, non-pressure boilers will be installed for the boiler pressure.

How to choose a china cheap 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.
