china coal fired hot water boiler seller

It is reported that since December 2018, with the market in Hefei, Anhui Province Lujiang County prison within the jurisdiction of the range 15 "coal to gas" boiler unit in the course of a full range of checking the newly installed gas boiler, while ensuring the area range within the boiler unit making a smooth transition "from coal to gas," the process, but also to ensure the safe use of the newly installed boiler.

The boiler before proceeding with the installation, install the unit you want to inform the local boiler installation of special equipment safety supervision and management department, inspection units installed during the installation and installation personnel qualification documents related strictly require the installation of the unit perform the required safety specifications and related standards, strict Charles undocumented and undocumented installers to install the unit.

When commissioning the boiler, the gas company and do the docking unit installation and use of the tripartite unit personnel to ensure the safety of boiler commissioning and trial operation of the boiler installation inspection, and actively promote the boiler unit boiler handle registration certificate and make contingency plans .

Note the choice of industrial boilers from the first industrial revolution to develop microbial technology, and upgrading various products continue to emerge, led us to the development of human civilization from the original backward to technological civilization, to the boiler, for example, since the last century, there has been a cylinder since the boiler-shaped, with the needs of science and technology and production, from simple to complex, from single to serialization, boiler technology are developing rapidly, the good reputation of industrial boilers companies choose to share precautions industrial boilers; first, the coal use; the design of the cell structure based on coal boiler components as the design basis, select the boiler should pay attention to adjust to the type of coal in the region. It recommended new, high-efficiency, high-tech, high-quality, durable industrial boilers; second, parameter selection; industrial efficiency boiler work normally when approaching the highest efficiency rating, as the load decreases efficiency has declined. Boiler capacity is generally selected: it generates a large steam than the actual gas consumption, such as the required parameters and actual parameters difficult to match industrial boilers, high boilers in this case a gear selection parameter. Selection of auxiliary boiler should also refer to the above principles, to avoid the "big horse car"; third, the number of choices; normal maintenance of industrial boilers and boiler shutdown is a number of factors, but also pay attention to: the boiler room shall not exceed the number of boiler economizers work load, install boiler economizer device purpose is to avoid too much heat when the smoke away. Improve the thermal efficiency of the boiler, is provided in the back pass boiler economizer heating surfaces, the use of flue gas heating boiler feed water, to save energy, economizer after the installation, the boiler increases the thermal energy required for heating the feedwater, boiler water and so reducing the temperature difference between the water supply, reduce the burden of heating boiler feed water. Cause excessive number of boiler economizer can not play a role, resulting in waste of energy; These are high-quality industrial boiler company to share some notes selected industrial boilers; vast land of our country, many places are rich in coal, resulting in different types of coal , which has also become a basis for selection of parameters and select the number of boilers enable us to be more effective in energy conservation, to achieve a win-win.

Steam boiler overpressure phenomenon and treatment of steam boilers refers to water heated to a certain temperature parameters and the production of industrial steam boiler, the water in the steam drum is heated to become vapor, fire emits heat in the furnace, it is the principle of the steam boiler. Steam boiler belongs to special equipment, design, processing, manufacturing, installation and use of the boiler must be supervised by technical supervision departments, users only get to use the boiler permits to use steam boilers. The fuel steam boiler (electricity, oil, gas) can be divided into an electrical steam boiler, steam boiler fuel, gas steam boiler three kinds; constructed according to the steam boiler can be divided into vertical, horizontal steam boiler, steam boiler mostly small and medium sized single , double the return of the vertical structure, large steam boilers and more horizontal structure of three return. Steam boilers and boiler overpressure phenomenon processing method, the phenomenon of over-pressure boiler steam pressure ⑴ sharp rise exceeds the allowable operating pressure, the safety valve pressure gauge pointer over the red line pressure is still elevated. When the interlock ⑵ overpressure protection device operation, overpressure alarm should be issued to stop the air blowing, the wind, coal. ⑶ steam temperature rises and steam flow. 2, boiler overpressure treatment ⑴ weakened rapidly burning, manually open the valve or bleed valve. ⑵ increase the water supply, while strengthening the lower drum sewage (you should pay attention to maintaining normal water level boilers), to reduce the boiler water temperature, thereby reducing the pressure drum boilers. ⑶ safety valve pressure gauge malfunction or all of the damage, emergency shutdown, safety valves and pressure gauges are to be repaired after the boost operation. When ⑷ endanger the safe operation of the boiler overpressure occurs, the buck should take measures, but too fast buck is strictly prohibited. The ⑸ serious boiler overpressure eliminate, to the shutdown of the boiler internal and external inspection, to eliminate the overpressure caused by deformation, leakage and other safety accessories and maintenance unqualified.

You have to know the energy consumption of boiler problems (flue gas oxygen content) 1, reasons 1.1 boiler leakage problems may increase the furnace exit of excess air ratio. 1.2 preheater leakage large. 1.3 or coal boiler load changes, wind, dust adjustment is not timely. 1.4 auxiliary burner throttle opening degree command deviations. 1.5 burner type, operation mode unreasonable. 1.6 determine the optimum boiler oxygen value is not accurate. 1.7 oxygen inaccurate measurements. 2, measures to address the problem of operational measures 2.1 2.1.1 Check to see if the fire door, be sure to close tight. 2.1.2 appropriate control the furnace pressure, amount of air leakage reduction furnace. 2.1.3 boiler load, when the quality variation, adjusting one, two air flow to maintain the optimal oxygen amount boiler control value. 2.1.4 maintain the normal water level in the water seal bottom, bottom to reduce the amount of air leakage. 2.2 carry out leakage test and damper characteristics before and after the test boiler maintenance routine maintenance and testing 2.2.1. 2.2.2 adjusted to optimize the combustion tests, the optimum value of oxygen boilers. 2.2.3 regularly test the air preheater leakage, provide the basis for air leakage control. 2.2.4 Periodic calibration of oxygen measuring devices to ensure the accuracy of measurement. 2.2.5 timely check and adjust the position of Flue Gas baffle system (such as: an auxiliary burner class inspection throttle opening degree, etc.), the identify problems in time. 2.3 2.3.1 downtime and a wear liner release duct, deformation, cracks, wear inspection process. 2.3.2 flue pressure test done to check the tightness of handling the leaking part. 2.3.3 flue damper position, the opening degree of chipping, deformation, loose seal, astringent card check process. 2.3.4 corrected assist air and the fuel damper flap opening position. 2.3.5 boiler, air preheater Leakage leak plugging. 2.3.5.1 boiler: furnace wall, roof sealing, see the fire holes, Manhole, bottom sealing plate is deformed, corrosion and tank leakage inspection process. 2.3.5.2 air preheater seal gap measurement adjustment, the deformation of the sector plate and curved plate, wear control check, the sealing gap adjustment mechanism inspection process. 2.4 2.4.1 transformation and a duct liner wear loose, deformation, cracks, wear inspection process, replacement, and a bluff body concentrator ceramic sheet, and silicon carbide wear measures. 2.4.2 boiler, air preheater, leakage leak plugging treatment. 2.4.3 the internal structure and the sealing means to transform the preheater, reducing air leakage. 2.4.4 boiler, flue joints and other advanced seal plastic material, to reduce leakage.
