three pass wet back structure gas steam boiler

In the near future, at home and abroad more than hazardous chemicals, major accidents have occurred, causing casualties and property losses. Is a profound lesson, Henan Energy Regulatory Office will co-Provincial Development and Reform Commission issued the "Notice on alternative transformation of the province's coal-fired power business major hazard (liquid ammonia tank)" and actively promote the province's power industry ammonia tank alternative transformation.

"National Development and Reform Commission and the National Energy Board to implement the views on the promotion of electricity reform and development of the field of safety of" clearly "to strengthen the major hazards source control, there are significant hazards during the production of coal-fired power generation enterprises should study the implementation of major hazards alternative rehabilitation programs. " Henan Province TV as fire, liquid ammonia tank safety risk management and control situation is grim. To actively implement the "opinions" requirements, Henan Energy Regulatory Office investigation and carefully combing the province's power industry the basic situation of major hazards, and actively carry out reconstruction work research initiative to communicate the situation with the Office of the Provincial Development and Reform Commission, the provincial emergency management, efforts to promote reconstruction work as soon as possible. "Notice" requirement province of the power generation enterprises should further enhance political stance, overcome difficulties, vigorously promote the major hazard (liquid ammonia tank) and Improvement, under the premise to ensure safe production, the province's coal-fired generating units and strive to 2020 in liquid ammonia tank renovation completed before the end of December. New coal-fired power generation projects should all use the technical route no major hazard.

Next, Henan Energy Regulatory Office will replace liquid ammonia around the transformation as an important safety regulation. For failure to complete the transformation of liquid ammonia replacement power companies, to be included in the list of key regulatory target, for there are significant risks or accidents in accordance with regulations to be strictly punished according to law, and urge enterprises to strictly implement the main responsibility to effectively prevent accidents, efforts to increase intrinsic safety level of the enterprise.

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. .

Run time, and the thermal conductivity of the gas boiler gas boiler after its long run, inevitably its scale and corrosion problems in the use of the process, the main reason the gas boiler scale formation is due to the water with ingredients hardness, high temperature, high pressure continuously concentrated by evaporation. Gas boiler furnace in which it is running a series of chemical and physical reactions will occur during use will effectively form a dense and hard scale on the heating surface, which would lead directly to lower the heat exchange efficiency and due to corrosion under the scale factors, it will lead to reduced boiler water wall furnace heat absorption. The outlet temperature of the gas boiler furnace during the course of an increase, so that losses will increase in the boiler, it will be effective to reduce the heat transfer in the water wall fouling equipment, so it is very likely to cause the water-cooled wall tube wall temperature results in an increase of the thermal conductivity of scale squib gas boiler waterwall at runtime only a few tenths of a steel material, when its heating surface fouling, so that the heat transfer will be impeded, in use process in order to maintain a certain boiler output, it is necessary to raise the temperature of the fire side. During the washing process gas boiler which may be employed in an efficient and environmentally friendly non-corrosive cleaning agent for cleaning the boiler, so that the device will expose the metal tube primary colors, because the reduction of algae and biological sludge fouling effect. Note that after the need for effective gas boiler furnace during ignition of smoke was observed and the temperature of the main steam temperature, the case where the pressure rise of the main steam, which is encountered after the boiler ignition temperature of tobacco will significantly increase the speed of the smoke or temperature Pianman It does not rise to the herd to immediately check the oil gun fire conditions.

Oil-fired boiler and gas boiler as the difference between the early stages of construction to complete our economy, our people's spiritual and cultural efforts to increase investment, with the attendant is demanding on the environment, air pollution is coal-fired boilers of large, first in the state it's now a rigorous, but the attendant is it a substitute for oil-fired boiler and gas boiler, that they have any difference? They belong to energy saving equipment, the combustion products of carbon dioxide and water, will not pollute the environment. The biggest difference is that they use different fuels, gas boilers use natural gas, city gas as the fuel, light oil, heavy oil which is used as fuel. In contrast gas boilers, boiler fuel cost is much higher than gas boilers, therefore, it is common for companies do not have a gas boiler operating conditions or institutions to use. Oil-fired boiler and gas boiler difference between: 1, different fuel: the former light oil, heavy oil as a fuel, which uses natural gas, city gas, liquefied petroleum gas as fuel. 2, the burner different: the former use of oil burners, gas burners later use. 3, different cost: the former high cost, about 1-2 times the cost of the latter. The same point fuel boilers and gas boiler: 1, the same boiler: the same tonnage same three pass wet back structure steam boiler or hot water boiler of the boiler body. 2, the same auxiliary components: in addition to the burner, auxiliary oil-fired boiler and gas boiler accessories equivalent tonnage same. 3, the same production process: The process of production and processing were carried out in accordance with the same process and production standards. These are the difference between the oil-fired boiler and gas boiler, want to help you choose.
