2019 best electrical industrial china boiler on sale
Description of the main steam pressure 2019 best electrical industrial china boiler on sale and boiler auxiliary equipment related to what is: the main steam pressure in the boiler, the relevant factors, there is what? For the new boiler, which prior to use, what needs work? As well as different types of boilers, auxiliary boilers on whether the same? These issues will be raised, its main purpose is to solve, so below, without further ado, to proceed immediately to save time and improve everyone's learning efficiency. 1. The main steam pressure boiler, and its related factors? Main steam pressure in the boiler, associated factors, and if, to generalize summary, then, there are mainly the following, are as follows: Factor 1: combustion boiler, which is enhanced or diminished. Factors II: specific changes in the heat transfer in the boiler, is has been enhanced or weakened. Three factors: the boiler heating surface, leaks and other issues, such as which waterwall leak or superheater. Four factors: the boiler feed water temperature has changed, or the burning flame height changes. Five factors: the boiler safety doors and pressure relief valve action, whether there will be corresponding changes or abnormalities.
Gas 2019 best electrical industrial china boiler on sale fault detection and troubleshooting if there is a problem in the gas-fired boilers used in the process, then we have to detect what is faulty, and to find a solution. When gas boiler failure, we want to all parts of the boiler to check to see if you can normally use, and then repair and replacement. Check whether the gas pipeline flow; ignition solenoid valve control circuit is in good condition; ignition operation of the solenoid valves; ignition operation of the solenoid valve, valves for operation. Inspection method: gas boiler operation to the ignition, the ignition solenoid terminals was measured with a voltage of 220V, line problems excluded. Removed after firing the solenoid valve, the power, the operation of the solenoid valve back, the valve body can be visually open, after the bypass valve is forced to open the main solenoid valve, normal ignition of gas, the gas may be excluded and the ignition solenoid failure. Gas to the ignition operation of the boiler, the ignition electrode with a 220V voltage at the terminals, after disassembling the burner, ignition electrode to ignition electrode terminal line is normal, the ignition electrode negative line problems. Careful observation some fouling ignition electrode and a flame detector probe above a measurement probe with a multimeter serious interruption, whereby to determine the cause of the misfire of the furnace because the ignition electrode fouling does not result in breaking an ignition signal. Solution: grinding with gauze and flame ignition electrode surface of the detector probe until complete removal of soot, with a multimeter, not all the surface of the probe disconnection. After putting out the fire main gas valve open normal combustion, wind turn opened fire door. Fault Analysis: Gas; demolition inspection gas through the main valve, the main valve and solenoid valve can work, can work regulator relief valve, the main valve is not working properly excluded, the front and rear ends of the regulator valve can be normal pressure, maintaining stable, excluding gas fault.
Use steam 2019 best electrical industrial china boiler on sale steam boiler explanation Di high efficiency, strong firepower, Di is a common production equipment, but also has some of its own Di dangerous if used improperly, it will cause unnecessary trouble. So familiar with the instructions for use steam boiler is necessary Di. So then, the editors based on years of experience, will use the specifications are summarized below. When the company receives a steam boiler, boiler Di for normal use, as well as business operators Di their own safety, we must strictly abide by the "Production Safety Law," "Boiler and Pressure Vessel Safety Supervision Provisional Regulations" "Steam Boiler Safety Technology Supervision" about provisions. This applies to a fixed pressure steam boiler water as a medium, comprising a coal-fired steam boiler, a steam boiler fuel, gas steam boiler. Use of the boiler plant Di technology should have the appropriate certificate, have both technical documentation and construction quality boiler installation supporting information. Enterprises must attach great importance to the boiler safety. Appoint a full-time staff responsible for managing the boiler equipment, improve the management of the use of boilers in accordance with code requirements. Formulate ensure the safe operation of the boiler structure according to the type of boiler, combustion and explosion-proof requirements and procedures, fire prevention, anti-virus and other security management system and the accident approach, in accordance with its strict implementation. Do not drink alcohol and posts and off-site. Boiler should be regularly repair and maintenance, the unit can not be forced to use any security risk boiler. Should be repaired before construction drawings and technical solutions. Repair of technical expertise required reference standards and relevant technical regulations boiler. After completion of repairs, should the pattern, material quality certificate, a certificate of quality inspection and repair and other technical information is stored in the technical archives plant boilers. Non-boiler room operator banned from entering the workplace. Foreign workers must be allowed to enter or be accompanied by the relevant approval of the leadership.
Recently, the letters and the ecological environment unit, the letter of "2019 best electrical industrial china boiler on sale air pollutant emission standards" in the "gas boiler exhaust pipe predetermined height of not less than 8 meters, within 200 meters from the building around the radius of the new boiler room chimney when was the tallest building in which the chimney should be higher than 3 meters "requirement questions.
First, the new urban gas boiler chimney should be performed outside the specified height is 3 meters above the surrounding buildings (there are many communities within 200 meters around the building height higher)?
Second, on the 20t / h steam boiler and above, and more than 14MW hot water boiler to be installed pollution-line monitoring equipment, this means that a single 14MW boiler or boiler means the total audience of 14MW?
Third, for example, I have more than 2MW heating station natural gas hot water boiler 7 units, exhaust gas through the two exhaust pipe emissions, the need to install pollution monitoring equipment?
A "boiler air pollutant emission standards" (GB13271-2014) states that "fuel, gas boiler stack height of not less than 8 m, particularly boiler stack height is determined by the EIA document approved. Chimney around the new boiler room when there is a building within a radius of 200 meters, the tallest building in which the chimney should be higher than 3 meters. when there is a building within 200 meters around the new boiler house chimney radius, "according to the provisions in the new urban area gas boiler should be implemented", the chimney should be higher than the provisions of the tallest buildings in more than 3 meters, "the.
Two, 20t / h steam boiler and above, 14MW and more hot water boiler must be installed in the line monitoring apparatus contaminants "14MW and more hot water boiler" means a single boiler.
Third, on the "exhaust gas through the two exhaust pipe emissions, the need to install pollution monitoring equipment" problem, according to "People's Republic of China Air Pollution Prevention Law" Article 24 "key sewage units should be installed, using air pollutant emissions automatic monitoring equipment, and environmental protection departments to monitor network devices, monitoring equipment to ensure the normal operation of public and emissions information in accordance with law. "provisions, as well as the" State Council on the issuance of three-year action plan to win the blue sky to defend the notice "(Guo Fa [2018 ] No. 22) "outfall height of over 45 meters of elevated source, as well as petrochemicals, chemicals, packaging, printing, painting and other VOCs emissions from industrial sources focus, the focus of sewage into the Directory of key areas should be basically completed by the end of 2019 to install flue gas automatic monitoring facilities, the country should be basically completed by the end of 2020 the automatic installation of flue gas monitoring facilities. "requirements, if the exhaust pipe where the company was listed as key units of sewage, flue gas monitoring facilities should be installed automatically, otherwise, no installation.
