2, June 2018 period from 1 July to 31 December 2018 for gas central heating area is built up or coal-fired boilers and other combustion facilities within the scope of the regulation into the second period, to be completed by 31 December 2018 out of the transformation.
Program remediation requirements:
1, the boiler must get out of the transformation of the city of Quality and Technical Supervision issued by the migration, retirement, cancellation of certificate or change a new boiler fuel use permit after; furnace, stove eliminated after the transformation of environmental protection must apply the change.
2, central heating is completed, it must use natural gas, liquefied petroleum gas, electricity and other clean energy combustion facilities outside the area out of coal-fired boilers, etc. after the transformation continued use.
3, central heating boilers planning area must use the central heating (gas) after the completion of the heating zone, will not have the heating conditions can use natural gas, liquefied petroleum gas, electricity and other clean energy as a transition.
4, into the "scattered pollution", high pollution and high emissions from industrial boilers and enterprise-wide to be eliminated.
5, for failure to complete boiler or eliminated within the rectification period, the Municipal Environmental Protection Bureau in accordance with the requirements of relevant laws and regulations and strict enforcement of its Municipal Quality Supervision Bureau will be canceled.
1, the safety valve should be mounted vertically in a high position in the pot business, set box.
2, between the safety valve and the drum or header, not equipped with access to the steam outlet pipe and the valve.
3, the lever-type safety valve should prevent movement of the self-apparatus and the weight limit leverage deviant guide tube, a spring safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly.
4, the rated steam pressure less than or equal to 3.82MPa gas steam boiler safety valve throat diameter of not less than 25mm; power greater than the rated steam pressure 3.82MPa boiler safety valve throat diameter not less than 20mm.
5, the safety valve and coal-fired steam boiler tubes, the cross-sectional area not less than the cross-sectional area of the valve inlet. If several valves installed together with a short tube directly connected to the drum, the cross-sectional area of the passage should not step short tube to 1.25 times the area of all the exhaust valve.
6, the safety valve should normally be installed exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust.
7, the safety valve exhaust pipe at the bottom should have received a place of safety posturing of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve.
8, rated evaporation to 0.5t h coal-fired steam boiler /, at least two safety valves installed; Rated evaporation 0.5t h less than or equal to electric boiler /, mounted on at least a safety valve.
Gas hot water boiler gas hot water boiler water quality standards and parameters of different capacities, in accordance with various operating conditions, the level of water treatment technologies and different long run, have different quality standard requirements. For details, see table below: This table is our current national standard "industrial boiler water quality" performance standards (GB1576-2008) mentioned. 1, the outlet for the rated steam pressure <2.5MPa, water as a medium, and a fixed soft drinks dual boiler hot water boiler, general use outside the boiler water treatment chemical, boiler water and feed water quality should meet the requirements of the table. 2, the rated evaporation <2t / h, and the rated steam pressure <1.0MPa gas hot water boiler of the boiler may also be employed and soft drinks dual dosing process in the boiler, the boiler must structure, corrosion and quality strengthen oversight, good dosing, sewage and cleaning, water quality should meet the requirements of the table. 3, pressure hot water boiler feed water for boiler water treatment should be carried out. 4, for hot water boilers and pressure hot water boiler rated power ≤4.2MW, you can also do the dosing process inside the boiler. 5, Feedwater should be outside the boiler water treatment chemical. 6, waste heat boiler water quality indicators and electric water boiler should be consistent with the type of required parameters with the boiler
Steam boiler is too many forms, take an ordinary fast-packed 4-ton steam boiler. Water is heated into steam in the drum and heat is emitted by fire in the furnace, which is the principle of the steam boiler. Say the boiler first the pot. The boiler is a drum boiler with water cooling. Two return pyrotechnic tubes are arranged in the left and right parts of the drum, and the front cigarette box in the front part of the drum is turned back. Between the drum and the bottom box, there is a drop tube and a water-cooled tube, forming the frame of the combustion chamber. There is a steam separator on the top of the drum to reduce the water produced by steam. The heating surface of the boiler is the lower part of the drum, water-cooled pipe and pyrotechnic pipe. The combustion part consists of a chain grate and a drive device, Add the boiler frame on the grate of the composition of the combustion chamber composition. Surrounded by refractories. Coal from coal hopper, there are coal gate to control the thickness of coal seam while sealing the front of the air. The lower part of the combustion chamber is the place where the blast enters, and this kind of boiler has great resistance and needs forced blast. Cinder, discharged from the back of the grate through hawk iron and sent out of the furnace by the slag extractor. From the back of the boiler, the flue gas goes forward from the first return pipe of the boiler, the second return pipe returns to the rear part of the boiler, and then goes into the dust collector to separate the ash, and then through the draught fan, it is discharged from the chimney. The induced draft fan is not only the exhaust gas, but also necessary for the negative pressure operation of the boiler. Steam boiler is pressure capacity Device, safety device is necessary. Essential water level gauges, pressure gauges, safety valves, thermometers, electric pumps that can replenish water under pressure, and steam pumps that can also be used in the event of power outages. Boiler water must be softened and water treatment equipment.
