new combined gas steam boiler for medical industry

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.

How to use cheap coal-fired boiler, gas boiler and hot water boiler: gas new combined steam boiler for medical industry burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, slowing exhaust speed, increase heat transfer, high thermal efficiency, reduce user costs of coal-fired boilers, gas boilers, to achieve environmental protection, energy saving effect. Dust content of exhaust gas can be reduced by 30% to 40%. Mounting position: the oil pump is mounted between the nozzle and the combustion chamber or the ambient temperature should not exceed 360 ℃. Combustion apparatus exhaust gas discharged air pollution is greatly reduced. An exhaust gas of carbon monoxide (CO), nitrogen oxides (NOx), hydrocarbons (HC) and other harmful components greatly reduced, harmful exhaust gases reduced by 50%.

The inlet speed of gas-fired hot-water boiler before start-up should not be too fast, usually no less than 4 hours in winter, and 2-3 hours in other seasons, especially in the initial stage of water intake. The inlet temperature of a gas-fired hot water boiler is generally 50 °C, so the difference between the feed water temperature and the steam wall temperature in the drum is less than 40 °C. For gas-fired hot water boiler, the inlet water temperature can be equal to that of steam drum wall without complete cooling, otherwise the inlet water speed should be slowed down. When feed water enters the drum, it always first touches the lower part of the drum. If the difference between the feed water temperature and the drum wall temperature is too Large, the inlet speed is fast, and the upper and lower walls of the drum, the inner and outer walls will have a large expansion. Bad, on the drum caused a lot of additional stress, resulting in drum deformation, serious cracking. Due to the thickness and slow expansion of the drum wall, the tube wall connected to the drum wall is thinner and expands faster. If the inlet temperature of the gas-fired hot water boiler is too high or the inlet speed is too fast, the expansion will be uneven, the welded joint will appear cracks and the gas-fired hot water boiler will be damaged. The inner diameter of the decompression tube is usually φ 7~13mm (water and steam), and its length should not be too long (< 60m). Straightness of pressure pipe If the diameter is too small and the length is too long, it will affect the dynamic transmission of pressure measurement and increase the dynamic error. The inner diameter is too large to be easily maintained and installed. Pressure pipes should not be placed in the horizontal part to prevent the accumulation of bubbles (when measuring liquids) and water columns (when measuring gases). The pressure tap shall be perpendicular to the flow of the medium. Pressure faucet must not have chamfer, flange and burr. When measuring the hydraulic pressure of an electrically heated new combined steam boiler for medical industry, the pressure outlet should be removed from the lower part of the pipe to prevent the gas in the liquid from entering the pressure guide pipe; When measuring the gas pressure, remove the pressure splice from the upper part of the pipe to prevent dust and dust in the gas The droplets enter the ignition line. The installation site of the electric heating steam boiler pressure gauge (pressure transmitter) should meet the environmental conditions (temperature, humidity, vibration, etc.) used by the instrument, and should be easy to observe, repair and ensure safety. Insulation should be laid on pressure pipes in high temperature media to avoid burning during flushing. Pressure lines are equipped with needle valves (for cutting off pressure in the event of pressure line failures during operation), auxiliary needle valves (for use with instruments, stopping, replacement), condensing coils and elbows (isolation elastic elements from high-temperature media), Easy to install sealing gaskets) as well as sewage valves and sewers. For special pressure measurements, it's still pressing. Install discharge valve, isolation room and so on in the force pipe.

It is reported that in March 15, Chifeng City, a special inspection of the pressure to carry out an internal inspection of industrial gas and new combined steam boiler for medical industry upgrade skills than the ability to test cum activity. Chifeng City, the special prosecutor, deputy director Jiao Wenxiang, deputy chief engineer Wang Shusen, deputy chief engineer Zhang Yulin and a pressure test of all personnel to participate. The ratio of the activity is divided into document review, site inspection, inquiry exchange three links, the city of Chifeng hotel comparison site inspection in WNS4-1.25-Q type of boiler.

In the field, compared to persons in accordance with the "boiler periodic inspection rules," "Boiler Safety Technology Supervision" and other relevant standards, test preparation equipment industrial gas steam boiler inspection, the document review, site inspection programs, projects, methods, inspection found defect assessment and treatment, inspection records and test the views of notice to fill in field operations and other aspects of comparison. Then the referee group of inspectors to participate in the comprehensive assessment ratio, the final nine inspectors compared the results were satisfactory. The ratio of inspectors to participate have said, by building a mutual learning platform for the exchange ratio of activities to enhance their own inspection techniques, in order to better carry out the annual inspection lay a solid foundation.

After comparison, the assessment team for each ratio of staff present in the actual operation problems raised rectification, so that each person than to recognize their lack of inspection in the presence of, as well as their ability to enhance the tailored inspection Program. In the future, I will continue to strengthen and enhance the inspection capabilities, adhere to the bottom line of thinking and problem-oriented, to provide a solid technical support for the safety of special equipment to hold the bottom line.
