Fire Tube Structure Gas Fired Hot Water Boiler

The preparation you need to do before the boiler is installed

The boiler is a device that supplies steam and hot water for industrial production or daily life. After the company purchases the boiler model, it needs to consider the installation problem. The installation of the boiler is directly related to the important steps of the smooth operation of the boiler, except for the installation of the auxiliary machine. Also need to pay attention to the preparation before installation.

1. Handling the registration of natural gas boiler installation: According to the “Safety Supervision Regulations for Steam Boilers”, the units that use the boilers should go through the registration procedures one by one. The boiler use unit shall have a person responsible for the boiler installation work, responsible for contacting the local boiler supervision agency and filling out the installation notice. When the boiler is installed, it must be attended by a furnace, and it is equipped with a pipeman, a fitter, a hoist, a cold workman, an electric welder and an auxiliary worker.

2. Determine the installation location and qualification of the boiler to determine the installation location. The boiler installation unit must have a boiler installation qualification certificate issued by the superior authority in accordance with the installation scope.

3. Inspection of boilers and accessories: Before the installation of natural gas boilers, the boiler body, combustion equipment, components, natural gas boiler auxiliary machines and accessories shall be inspected and accepted according to the drawings, and records shall be made. If it is found that the relevant standards are not met, it shall be promptly submitted to the factory. .

Phase out coal-fired boilers, promote air pollution control is an important measure to improve the air quality of the environment. Zhangjiakou City, Hebei Province, according to the central and provincial government deployment requirements, in-depth launched out of control for coal-fired boilers, and comprehensively promote the city's 35 tons of steam / coal-fired boiler sales and less "clear" work to ensure the city's air quality improved and enhanced.

The phase-out of coal-fired boiler from the following three points.

First, the coal-fired boilers carry out a comprehensive investigation work.

Depth investigation and the remodeling phase out coal-fired boilers and "coal to electricity", "coal to gas" and so on, electricity consumption by verifying the number of boilers and eliminated the need for the transformation of gas to develop a control list in 2018 coal-fired boilers to natural gas, electricity security for the ability to determine the "coal to electricity", the number of "coal to gas," the boiler. Do a boiler in a table, as well as finishing the complete elimination of the transformation of the way, rectification, acceptance, responsibility for people's list, to lay the foundation for the next phase out coal-fired boilers governance.

Second, carry out the phase-out coal-fired boilers.

Carry out a comprehensive phase-out 35 tons of steam / hour and below the coal-fired boiler, stove, operating a small coal stove, the main urban built-up areas and the urban fringe, and built-up areas within the county Economic Development Zone range, a ban on new coal-fired boilers other regional ban on new 35 steam tons / hour and below the coal-fired boilers. For central heating central heating in the official website of the area covered, when not incorporated central heating, heating mode using a variety of propulsion power, natural gas, industrial waste heat utilization, and energy from the source to control pollution.

Third, strongly promote the boiler-depth treatment.

Focus on pollution control bulk coal, comprehensive transformation of the use of coal boilers and generators. Stoker addition, stoker furnace, over the remaining 65 tons of steam / h coal-fired boiler to complete the transformation process ultra-low emissions, the city above 35 t steam / hour is then mounted boiler line monitoring devices, and environmental protection authorities and networking, production facilities and quality facilities simultaneously, real-time monitoring.

What are the advantages of the fire tube structure fired hot water boiler often a little later sure understanding of the principles and methods of using hot water boiler, Henan so fast boiler editor here is also not introduced because a little later thirty-two. If only the gas hot water boiler favorite words, web editor can explain a little later period of his merits, the following look at what advantages it fired hot water boiler in the use of step. Simple: bank up a fire, ash, add water, thanks to ignition this step, Fenghuo is the first time the ash, the ash cleared clean, then covered in coal bucket full of coal door only. Environmental protection services gas hot water boiler is sure to meet the economic and social development, and therefore, gas hot water boiler full of hospitality by everybody, and its requirements are very large, the advantages of gas hot water boiler itself Del it changes the space Philippine law is enormous. Automatically raised temperature, gas hot water boiler definition table is automatically significantly depending on temperature and water level, gas hot water boiler 24 hours stoker 2 can, like that gas hot water boiler can be controlled to maintain the temperature of day, is so out of use will be more convenient. Investment, low operating expenses: reasonable biomass combustion mechanism based sauce, renovation spending time low for a variety of equipment, heating profit down 60% lower than oil-fired boiler to run than gas-fired heating reduces profit down 40%, is hot air stove, oil furnace, gas furnace transformation of low-carbon environment, the most suitable replacement. Simple, fast and easy maintenance: the use of fixed-frequency automatic feeding, wind ash, simple operation, small amount of work, only single person on duty, biomass burner stove is a lot of companies the most appropriate. The fuel to the original wide: this burner to wood, wood pellets as a raw material, high calorific value, straw particles and avoids coking caused due to facilitate the situation. Heat is very high: the ability to quickly raise the temperature, but there is no dust, not to mention there is no cause smoke, like that of the nearby environment made it difficult to cause any damage. Application of Gas hot water boiler is very simple, he has a very unusual design, is so unique design can have a decorative role, but also there are gas hot water boiler structure is all very unusual . Hot water boiler obvious effects of eco-friendly low-carbon eco-environmental effects of environmental hot water boiler obvious: the secondary energy source is biomass fuel, maintain ecological use of renewable energy. High temperature press section ignition step, dust is low NOX, SO2, dust and sewage treatment, is gasoline and diesel (gas) burner, electrical heating etc. The most suitable alternative. Tar smoking, waste water and other waste water treatment: pyrolysis using pilot step, tobacco tar, or the like to immediately ignite a gaseous method, solving the high tar content of the biomass gasification bottleneck, avoiding hand caused by tobacco tar Water pollution gases. Heating temperature is increased: with the wind again using step, the furnace pressure in the jet region 500-700mm water column to ensure all of the normal stream. Continuously feeding the continuous production of flame stability, high temperature section temperature exceeds 1300 ℃, is added to industrial applications. Thus says the advantages of hot water boilers are very much hope that a little later steps in the application can make use of features to get plenty of shape.

Hot water boiler which is not equipped with no impact can cause demineralizer 1, the waste fuel boiler fouling occurs, resulting in poor heat transfer performance of heating surface, so that heat generated by the combustion of the fuel can not be timely delivered to the boiler water, but a large amount of heat is smoke away, resulting in exhaust gas temperature is too high, if the exhaust gas loss increases the thermal efficiency of the boiler will be reduced. In order to maintain the nominal parameters of the boiler, fuel must be increased, thereby wasting fuel. About 1 millimeter scale waste fuel ten percent. 2, the heat receiving surface is damaged due to deterioration of the heat transfer performance, fuel combustion heat is not quickly transmitted to the boiler water, resulting in the furnace and the flue gas temperature. Thus, the temperature difference on both sides of the heating surface increases, the metal wall temperature, a decrease in strength. Under pressure pot, bags and even blasting will occur. 3. Reduce heat boiler output due to the deterioration of the performance of boilers, need to consume more fuel to reach the nominal rate of evaporation. However, with the increase in the scale thickness, the volume of the furnace becomes large, the fuel consumption is limited. Therefore, it is possible to reduce the output of the boiler. 4, the corrosion damage to the metal: oxygen in the water, acid, base materials will corrode the metal surface of the boiler, it is thinned, recess or perforation, thus reducing the power of the boiler, seriously affect the safe operation of the boiler. 5, in addition to improper operation Priming outside, when the boiler water contains more sodium chloride, sodium phosphate, and silicides oil, boiling or evaporation process boiler water, boiler water occurs when soap and organic base when Teng because soda will produce compost. Foam liquid surface, formed soda pool. No softening, easily scalable. Due to the continuous evaporation steam, boiler of calcium, magnesium, high impurity concentration is 30-50 times that of natural water, fouling rate beyond our imagination, only six months to a year, from 1-2 mm.
