It is understood, Shaanxi Province, 2018 - Continuing to promote the 2019 inspection work in key areas of defense sky war, now in its third phase. November 22, according to the requirements of the program of work for the inspection team to carry out all the Guanzhong area of Shaanxi Province counties (cities, districts) inspection work, inspected 262 units, identify problems and 49, have been transferred to the supervision of Shaanxi Province 20 .
20 environmental issues in the supervision, accounting for 8 in Xi'an, Weinan City, accounting for 7, Baoji City accounted for two, accounting for two Xianyang City, a Korean city of Tongchuan City, Yangling Demonstration Zone and the New West Ham is not problem found.
More units found the problem, companies of "scattered dirt," the one, accounting for 5%; industrial pollution prevention and control 10, accounting for 50%; a coal-fired boiler renovation, accounting for 5%; comprehensive management of dust 1 , accounting for 5%; complaints 4, accounting for 20%; at three open burning control, accounting for 15%.
Can be checked by the quality of the installation commissioning of boilers manufacturers in punes, auxiliary equipment, control systems and other equipment; ensure that the pipe surface clean and free of debris inside the pipe; a preliminary understanding of the main operating characteristics of boilers and other auxiliary equipment; inspection of boiler control systems, protection systems rationality and reliability; initial inspection of boilers and auxiliary equipment full load capacity; found important deficiencies of boilers and auxiliary equipment, etc., in order to take timely and effective measures; but also trained personnel to know about running and running on the system performance the initial adjustment for trial production and commercial operations in future.
Nowadays, the use of gas-fired steam boiler has become more and more frequent, and the boilers all over the country have changed the use of gas-fired boiler with each passing day. Although the domestic professional gas-fired steam boiler is stable in operation and less energy-saving and consumption-reducing in sewage discharge, it is necessary to use proper maintenance in the case of long-term non-use in order to carry out normal use. Specific gas-fired steam boiler maintenance methods in the case of not in use and see below for detailed analysis of the following:
1: dry maintenance of gas-fired steam boilers should remove the boiler water after shutdown, and then thoroughly remove and rinse the dirt from the interior. And keep the oven dry so as not to be seduced. You can dry the chamber with a light fire, but not with a fire. Also be careful to close all hand-hole piping valves and place the quicklime tray in the drum. Check the boiler at least three months without using a gas-fired steam boiler for a long time. If the quicklime in the chamber is crushed into powder, the new lime needs to be replaced immediately to ensure that the drying protection in the furnace of the gas steam cooker is not corroded by moisture.
2: in addition to dry maintenance, wet maintenance of gas-fired steam boilers can also be done by means of wet maintenance, which is to remove internal dirt after discharging the water in the furnace, and to fill the chamber with treated water and then heat it to the required temperature. The gas in the water is then discharged out of the furnace and all valves are closed. In this way, the furnace is filled with water to complete maintenance. Of course, wet maintenance should not be used in cold weather to prevent water icing and damage to the tank. It can be seen that the gas-fired steam boiler in the case of not in use is mainly dry and wet method of maintenance, which kind of specific use Maintenance method according to different site and climate conditions to make flexible choice.
Matters needing attention and standard flow of boilers manufacturers in pune periodic sewage discharge operationOperational notes and standardized procedures for boiler periodic discharge: 1. Periodic Sewerage notices 1. The main value of the furnace should be contacted before the discharge is discharged, and the steam turbine can be approved before it can be carried out. 2. When discharging water level is normal, after discharge, check whether each sewage door is closed tight. 3. Sewerage doors should not be opened to more than 30s, can not open two or more sewage doors at the same time, in order to prevent damage to the water cycle. 4. Open the drain door slowly in case of water shock. In case of water shock, close the valve until the shock disappears, and then slowly open the drain door. 5. When operating the valve, you should stand on the side of the valve, strictly prohibited Right to the valve. II. Discharge operation flow 1. After receiving the scheduling task, labor protection supplies dressed neatly, with a special F wrench, on the spot open the general gate. 2. Open all the doors, contact the DCS screen of the furnace to open the corresponding discharge electric door, after the discharge, first close the second door, then close the door, one by one, one by one. All sewerage is over, close once door of each discharge and main gate of sewerage 3. When discharging water, we should pay close attention to the water level. If there is any abnormal water level or accident, the discharge should be stopped. For 2 hours, the door cores of each discharge door shall be checked for leakage, and if the drain is lost, the drain door shall be opened promptly once. Note by removing residue that may be stuck in the core of the door (boiler principal value should be contacted before operation): the whole drainage process should be in close contact with the DCS operator.
