When the weather gets colder and colder, people will choose different ways of heating, one of which is more convenient is the fuel-fired boiler, but many people do not understand his use, so take a look at the following. Classified oil-fired boiler is a kind of boiler with many kinds of oil such as diesel oil, waste oil and so on. Its general structure and arrangement are similar to coal-fired boiler, and the common classification is mechanical type and steam materialized type. The characteristics of the bottom of the oil-fired boiler are to make the bottom of the furnace inclined to the back wall, which is the bottom of the heat preservation furnace, in order to obtain good combustion characteristics. This kind of boiler, for those who don't have a natural gas pipeline, Hope the boiler can run normally low cost, then the fuel-fired boiler is a very good choice. The fuel-fired boiler is an important symbol of the progress of the times, in order to serve the human being well and further perfect according to the needs of the people. Oil-fired boiler is designed in accordance with certain commercial standards, to a certain extent to ensure the excellent boiler, but also to a certain extent to improve the heat absorption strength of the boiler, then how should we use it? Design problems according to the oil-fired boiler inside the design of the boiler inner tank is larger, can store steam will be corresponding to more, suitable load capacity will become stronger, can be To meet the needs of different users, the cleaning of internal gall is also more convenient. The fuel-fired boiler with fire tube structure adopts the structure of triple-reflux fire tube, and the flame burns in the combustion chamber with high thermal efficiency, energy saving and consumption reduction, so it is economical and convenient to use. According to the unique design of the boiler, the use of the oil-fired boiler needs to find a set of operation steps suitable for the boiler and give full play to its function.
Technical characteristics: the overall cost of natural gas boiler is half the coal-fired boilers, and operation costs are four times as coal, a ton of steam needs to burn about 80 cubic meters of natural gas, and coal-fired no more than 0.185 kg, the economic accounts will be considered . Select the gas boiler it under certain conditions choice of last resort. As well as on the performance of the gas is better than coal. In principle, they are heat transfer equipment, the difference is that on combustion, complex grate or coal, coal preparation, etc. as well as coal needs, while gas only burner that simple. Use of cleaning gas boiler: boiler after a long run, the inevitable emergence of scale, mainly due to the scale of the problem of corrosion, formation of boiler feed water with hardness components, through subsequent high temperature and pressure continuously concentrated by evaporation in a furnace a series of physical and chemical reactions that ultimately form a hard heating surface, a dense scale, resulting in reduced heat transfer and the effect of corrosion under the scale factors, will result in reduced boiler waterwall furnace heat absorption, furnace outlet temperature of the boiler is increased, so that increased boiler losses. After scaling while reducing the heat transfer within the water wall, water wall tube wall temperature may lead to increased water wall lead to burst pipes, affect the safe operation of the boiler. The first of scale is detrimental boiler, the boiler is the main cause of accidents, the danger main problems: wasting a lot of fuel: Because only one of very few steel thermal conductivity of scale, so when the heating surface fouling will heat blocked, in order to maintain a certain boiler output, it is necessary to increase the temperature of the side of the fire, so that the external radiation and flue gas heat loss. Now it can be used efficient and environmentally non-corrosive cleaning agent gas boiler cleaning, cleaning Fu World Tektronix cleaning agent scale was completely dissolved, the equipment expose the metal tube primary colors, because the reduction of algae and biological sludge fouling effect. At the same time stripping the role of iron oxide and iron oxide Asia, extended gas boiler service life, reduce energy consumption and improve productivity.
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. .
Fangkuai Boiler has carried out a large-scale welding revolution, eliminating traditional manual welding operations with low efficiency, low accuracy and poor stability, and converted it to the use of mechanical welding equipment with high efficiency, high accuracy and high stability for automatic operation . Realize welding automation of all important parts from the drum to the tube sheet. The submerged arc welding, argon arc welding, carbon dioxide welding and other welding details of the process have also made corresponding intelligent changes, workers' welding environment is cleaner, and the quality of boiler welds is more guaranteed.
