2500 kg industrial boiler cost
Common steam 2500 kg industrial boiler cost overpressure accident approach: 1, the phenomenon (1) steam boiler overpressure sharp increase in steam pressure, exceeds the allowable working pressure gauge pointer over the "red line" safety valve after the pressure is still elevated. (2) the operation of the device is the interlock overpressure protection, should send overpressure alarm signal, stops the air blowing, the wind, coal. (3) steam temperature and steam flow rate reduction increases. 2, to treat boiler overpressure (1) weakened rapidly burning, manually open the valve or bleed valve. (2) increase the water supply, while the lower reinforcing blowdown drum (It should be noted at this time to maintain the normal water level of the boiler), in order to reduce the temperature of the boiler water, thereby reducing the pressure in the boiler drum. (3) as a safety valve malfunction or all of the pressure gauge damage, emergency shutdown, safety valves and pressure gauges are to be repaired after the boost operation. When endanger the safe operation of (4) Boiler excessive pressure, blood pressure should take measures, but too fast buck is strictly prohibited. (5) boiler overpressure eliminate serious, to the boiler furnace internal and external inspection, to eliminate the overpressure caused by deformation, leakage and other safety accessories and maintenance unqualified. Steam boiler accident and the type of treatment and the boiler safe to use common sense
The method of mounting the valve 1 gas hot water 2500 kg industrial boiler cost, hot water boiler gas valve position to facilitate installation and maintenance operations taking nice. When mounted horizontally, the stem should be facing, but not downwardly. The valve on the pipe height, can be installed horizontally. 2, the same room, the valve on the same device should be neatly arranged symmetrically, suitable height on the riser the valve is 1.0-1.2 m. Alongside the valve riser, which is preferably the same as the central elevation. 3, when the heavier mounting of the valve is provided a valve holder. It is noted that the valve mounted in line with the arrow pointing direction of the pipe. 4, when the valve mounting flange, should ensure that the two end faces parallel to each other and concentric flanges, can not use double gaskets. For ease of disassembly, the valve should be equipped with a one threaded joint. 5, when the valve mounting flange, threaded bolt diagonally noted, forced uniform asbestos mat to prevent deformation of the body or cause meandering. When the valve is connected with the pipe flange, the valve should be closed. When a welded connection, the valve should be slightly opened.
Recently, market supervision bureau issued the Notice on Strengthening the National Energy Board within the scope of the power station 2500 kg industrial boiler cost piping material quality safety risk prevention and control (the "Notice"), to further enhance the quality and safety supervision and management of boiler tubes, effectively preventing security risks, protect the power production safety , as follows.
First, carry out the verification of boiler tubes
The electricity business, special equipment manufacturers to immediately organize boiler tube inspections, to verify whether the focus of the pipe to meet the technical conditions stipulated orders, including the source, size, quantity, quality certificates, raw material procurement contracts, procurement contracts and other piping components. For imported pipe material, but also the verification of the customs declaration, commodity inspection report (proof of entry inspection and quarantine of goods), combined with the production, inspection and testing during use and operation of the situation, in-depth investigation pipe quality boiler safety issues and risks.
Second, effectively prevent security risks
Boiler pipe quality and safety hazards or other problems threatening the security and stability of power station boilers, power companies, special equipment manufacturers to take practical measures immediately, the complete elimination of quality and safety problems; there are significant quality and safety problems, it should stop running generator sets , boiler or stop production and sales of the pipe elements, and replace the boiler pipe complying with relevant standards.
The actual boiler pipe manufacturing unit is unknown or if there are doubts, the relevant information or data can not be traced authenticity, power enterprises, special equipment manufacturers to immediately in accordance with industry standards, inspection and testing institutions have entrusted the appropriate qualifications for boiler tubes were identified test. Test results show that failed boiler or pipe quality does not meet the technical requirements stipulated in the order, power companies, special equipment manufacturers to eliminate hidden dangers in a timely manner or be replaced.
Third, strengthen the source of control boiler pipe
Special equipment manufacturing enterprises, power enterprises should strengthen boiler pipe source control, in strict accordance with the standard provisions of China's relevant laws and regulations and orders technical conditions agreed to carry out boiler pipe design and manufacturing, procurement orders, admission acceptance, inspection and testing, installation and commissioning work, resolutely eliminate substandard or counterfeit boiler pipes enter the field of electricity production; to strictly implement the special equipment safety supervision and management regulations, establish and improve the technical archives and long-term care, to ensure that relevant information can be traced back.
Special equipment manufacturing enterprises, power companies are finding there are significant quality and safety risks of boiler tubes, to report to the local market regulators, power management departments and the National Energy Board sent energy regulators, and to take effective measures to thoroughly rectification to ensure the safe operation of generators . Provinces, autonomous regions and municipalities and Xinjiang Production and Construction Corps Market Authority (Hall Commission) should work together with the same level of power management departments, the National Energy Bureau sent energy regulatory agencies and other units, the organization of supervision and inspection, supervision and hidden rectification, effectively preventing security risks.
Industrial Steam Boiler in Thermal Power Plant Efficiency
The percentage of total heat exported by outlet steam in the total heat supplied by the fuel is called industrial steam boiler efficiency. It includes with thermal efficiency, combustion efficiency & fuel to steam efficiency. Industrial steam boiler efficiency depends upon the size of boiler used. A typical efficiency of steam boiler is 80% to 88%. Actually there are some losses occur like incomplete combustion, radiating loss occurs from steam boiler surrounding wall, defective combustion gas etc. Hence, efficiency of industrial steam boiler gives this result. Industrial steam boiler for sale in ZG Boiler is with the complete combustion, least loss, and it is high efficiency industrial steam boiler.
