On the outskirts of the gas pipeline construction is temporarily unable to reach enterprises in the region, while ensuring security compliance cases, it can be in the form of non-natural gas pipeline, and implement an orderly transition after the completion of the pipe network. Encourage alternative gas supply business enterprises to provide gas price discount for the gas boiler.

10KV for the implementation of alternative electric boiler, 35KV and other business expansion project, to which the power supply capacity of the electrical part of the boiler, according to the city's non-resident business expansion project quota standards, engineering fees charged by half.

Environment departments to strengthen law enforcement and inspection of boiler units, fuel use, operation and maintenance, equipment maintenance, inspection, non-functioning facility once found, according to the law severely punished; at the same time, strengthen supervision and monitoring, if it is found excessive emissions, according to law strict punishment.

Boiler units and boiler mentioned standard transformation service units bear the main responsibility for the boiler safety issues involved. Site construction unit must have the appropriate boiler manufacture or installation (reconstruction) qualification, boiler commissioning personnel must have the appropriate special equipment operator certificate. Prior to the construction site mentioned standard boiler units to implement the transformation, boiler location should be informed in writing of special equipment regulatory authorities.

The district government is the responsibility of the main boiler to mention the transformation of the standard, according to the "ground principles" to promote the transformation of the boiler. Combined with the actual circumstances of the district reform implementation plan, accelerating the construction of facilities to ensure timely completion of the task of transformation, to ensure that policies and financial support in place.

SZS series oil and gas fired d type water tube fired boiler with D-type double drum-type packaging water pipe structure, less occupied area, but also make the fuel fully burned. It also uses a high heat-resistant material as a thermal insulation layer, good insulation properties, the back of the boiler installed with flue gas condensing recovery device, improve the thermal efficiency.

What is the main danger steam d type water tube fired boiler? The main danger emergency steam boiler 1, surveillance, hazard control boiler steam boiler regular inspection tours, and monitor pressure, water level, temperature and combustion conditions to control the boiler operating conditions. And to take timely measures to ensure safety. 2, the processing operation of the steam boiler in special circumstances: (1) water shortage phenomenon: When the boiler water, the water level below the water table level limits not visible, low water level alarm emits an alarm, bell lights, low interlocking means so that the water level blower, fan, etc. closure operation; boiler exhaust gas temperature rise, a serious lack of water, lake taste top coke production, the door can be seen from the red-hot waterwall tubes, tube deformation or even explosion pipe, can be heard blasting sound, smoke and steam discharged from the door to see the fire door. Treatment: When judged as a serious water shortage, should an emergency shutdown, non-serious water shortage boiler water to the boiler. Immediately stopping the supply of fuel, the wind stops blowing weakened, the front portion of the coal grate furnace Pa, the maximum switch the grate, combustion slag hopper falls quickly, with irrigated off, after extinguishing the fire, stop the wind, open ash door, the door to promote accelerated cooling. Note: Do not feed water to the boiler, shall take measures to prompt blood pressure, prevent the accident, to refrain from watering methods to the furnace fire put out the fire. (2) boiler overpressure phenomenon: a sharp rise in steam pressure, exceeds the allowable working pressure gauge pointer over the "red line", the safety valve, the pressure is still elevated, issued overpressure alarm, steam temperature and steam flow rises cut back. Processing: weakened rapidly burning, manually open the vent valve or safety valve, to increase the water supply, sewage increase (normal water level at this time to keep the boiler), thus reducing the temperature of the boiler water a boiler drum pressure decrease. (3) boiler tube phenomenon: the waterwall tubes blasting significant audible pops or jet sound, until the furnace by the combustion pressure becomes the negative pressure combustion, flue gas and steam and has viewed from the fire door, the door does not close, etc. discharge, although the water supply amount is increased, but difficult to maintain the normal water level and the pressure reduced, the amount of water to abnormally greater than the amount of steam, the exhaust gas temperature decreases, the chimney white smoke, the furnace temperature is reduced, or even extinguished, water flow out of the bottom of the boiler. Treatment: furnace tube rupture is not serious and can maintain the water level when the accident not to expand, may reduce short-term load operation, serious burst pipe and the water level can not be maintained, must be an emergency shutdown. But the wind should not stop, should continue to Sheung Shui, lower wall temperature. Such as: lack of water wall overheating, while burst pipes, emergency shutdown should be prohibited to the boiler feed water, the withdrawal of the furnace over the fire as soon as possible, reducing the furnace temperature, reducing the degree of superheating boiler. (4) steam boilers will produce full of water, such as priming scene of the accident, should take timely and effective measures to eliminate given. (5) boiler operation, in the event when one of the following circumstances, should immediately shutdown :( a) boiler water level below the lowest water level gauge visible edge; (b) increasing water supply and other measures, but the water level continued to decline; (iii ) boiler water level exceeds the highest visible level, the drainage can not see the water level; (iv) to pump all the water system failure or malfunction, not bottled water to the boiler; (e) all of the water table or valve failure; (vi) is set in a stripping all space gauge failure; (vii) damage the boiler element and endanger the safety of operating personnel.

Note the use of the gas d type water tube fired boiler which has a new gas boiler is used for heating boiler equipment, now this device has demonstrated its exceptional thermal performance in many areas of our country, and want to make a reasonable quality in use gas-fired boiler to play the best features you should master the operation of the Notes, the following small series tell you about the use of gas-fired boiler precautions have what? (1) selection of good thermal and oxidative stability, strong anti-coking HTF. Be careful not to choose scented and deep color when purchasing gas boiler conducting oil conducting oil. HTF with the life of carbon residue, an acid value, flash point, viscosity 4 which measure. Consumers need to make semiannual oil testing the use of gas-fired boiler, conducting oil to grasp the good quality operation. Found in gas boiler runtime problems timely replacement of heat-conducting oil, and find out the cause and prevention of deterioration of thermal oil in advance. At the same time we must strictly do HTF different product numbers do not mix. (2) strict quickly and decisively, always observe the rules should be in accordance with the use of gas-fired boiler, anxious to avoid the fire to heat up, over-temperature, over-pressure, to take urgent measures to shutdown the expansion tank the oil level and oil temperature, such as lack of oil should be added to prevent air and water into the oil circulation system. And direct contact with air after the heat conducting oil will accelerate the reaction it is necessary to prevent direct contact with the air temperature oil. (3) improve the thermal efficiency of the gas boiler hot oil boiler, timely removal of grime on the gas boiler furnace line the inner wall and the wall plate to ensure good heat transfer, and should as far as possible the use of better quality coal, the combustion gas boiler furnace temperature must be reduced to the specified range in order to shut down the circulation pump when the heat generated by coal timely and comprehensive transfer to the HTF (4) shall not be closed for oil circulation pump shutdown boiler insulation, each time you turn the gas boiler should be asked to turn on the circulating pump. In case of a sudden power failure or circulatory failure, in addition to using external cooling ventilation must be replaced with a cold heat transfer oil. The above is several precautions to use gas-fired boilers, and consumers regular cleaning conducting oil pipelines, gas-fired boilers to reduce the impact attachments generated at high temperature for conducting oil quality, the only way to ensure the most professional presentation gas boiler optimum heating efficiency to help consumers get a better life.
