metallurgy gas water boiler manufacturers

Horizontal hot metallurgy water boiler manufacturers a few precautions, overpressure accident 1 boiler, steam boiler overpressure phenomenon of (1) a sharp rise in steam pressure, the pressure exceeds the allowable working pressure gauge pointer over the "red line" is still working pressure safety valve l high. (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 shutdown of the boiler internal and external inspection, to eliminate the overpressure caused by deformation, leakage and other safety accessories and maintenance unqualified. Second, an accident boiler water, boiler water shortage (1) below the minimum safe water level line, or can not see the water level, the water level gauge glass (plate) as a white. (2) as a full-color water level gauge vapor instruction color. Low water level alarm signal (3) water level alarm occurs. (4) low water interlocking means, the water level should be below a prescribed value blower, Fan, grate reduction motor stops running. (5) a sharp rise in the superheater steam temperature, higher than the outlet steam temperature. (6) boiler exhaust gas temperature rises. (7) the water flow is less than the steam flow, causing Should the water tube due to tube cracking or economizer, an opposite phenomenon occurs. (8) When a serious water shortage, can smell the burnt smell. (9) When a serious shortage, the door can be seen from the red-hot waterwall tubes. (10) a serious water shortage, the furnace tube may rupture, then can hear the explosions, smoke and steam from the door, watching spray the fire door. 2, boiler water treatment (1) through the "waters", sentenced to severe water shortages, emergency shutdown must be prohibited blind to the boiler feed water. (2) through the "waters" sentenced to a slight lack of water, it should reduce fuel blast, the wind, and slowly feed water. Third, full water boiler 1 accident phenomenon (1) above the maximum allowable water level line, or can not see the water level, the water level gauge glass (plate) dark color boiler filled with water. (2) all of the water phase as a color level gauge indication color. High-water alarm signal (3) water level alarm occurs. (4) decreased superheated steam temperature. (5) water flow is not normally greater than the steam flow. (6) water in a large number of sub-cylinder, severe trap operation. (7) with a large amount of water steam severe, increased salinity, water hammer occurs in the sound of the steam pipe, the steam connection flange outwardly dripping take place. 2, steam boiler full of water treatment rinse water table, determined to be minor or serious full of water full of water. Method: Close water table, the water pipe connected cock, then open drain cocks As can be seen from the decreased water level, indicating a slight full of water, the water supply is stopped, the drain valve open, put to the normal water level. Such as severe filled with water due to take emergency shutdown measures.

2019, Nanjing for more stringent ozone pollution, for volatile organic compounds, governance and control measures nitrogen oxides unabated.

Nanjing Ecological Environment Agency staff members at atmospheric introduction, with the recent temperature increases, there has been a trend in some parts of ozone exceeded. This summer, the environmental protection department will introduce stricter air pollution control measures, starting from the two aspects of governance volatile organic compounds and nitrogen oxides to reduce ozone pollution.

It is understood that Nanjing will be completed this year 44 companies VOCs governance and thermal power, cement, bricks and other building materials industries fugitive emissions-depth treatment in the city in batches with a gas-fired boiler 936 units, the implementation of the nitrogen oxides governance Sector Engineering; city station 475 to achieve ultra-low emission particulate biomass boilers, for the privately polluting fuels blended biomass boilers embodiment eliminated. It is worth mentioning that the revised "Nanjing Atmospheric Pollution Prevention Act," to be implemented next month. Among them, organic solvents, paints use, as well as volatile organic compounds corporate governance and management have put forward new demands.

Electric steam boiler flue of accumulating a certain amount of soot how to deal with? Electric steam boiler furnace cleaning backpass long-term non-stop, accumulating a certain amount of soot or carbon black. Solution: When the temperature drops below the flue 50 ℃, check before entering the flue tail heating surface, and should completely remove the flue soot. If not burning, can be re-started ignition; if burning, should be replaced, repaired burning member; large negative pressure of the combustion chamber, so that gas will be no time to burn into the electric steam boiler tail. Solution: When the exhaust gas temperature close to the temperature of the injected steam, or less than 150 deg.] C and more stable during 1h openable inspection hole inspection, after checking element determines the source of fire, the ventilation fans before starting. When shutdown or electric steam boiler fire, air gun valve is not closed. Solution: strengthen the electric steam boiler feed water and turn on the water, open the valve or economizer recirculation tube to protect the economizer being burnt; lower start, the furnace temperature during shutdown, unburned fuel in the furnace . Solution: fire extinguishing devices immediately into steam, carbon dioxide or other fire extinguishing devices; burn improperly adjusted, with insufficient wind or with the wind unreasonable. Solution: Close the flue duct and baffle around the door opening, start sending prohibited, induced draft fan.

the fuel used in the horizontal boiler is natural gas which is transmitted to the boiler room through the gas pipe.The gas is convenient and less pollution. But in the using process, the probable leakage not only increase the fuel costs of enterprises, but also contain security risks, the following is the solving measures proposed by engineer:

1. the natural gas leakage treatment. For outdoor buried gas pipeline leakage, the Gas Co should be immediately informed to cut off the gas source, and the person in charge should report to the responsible departments. According to the natural gas leakage emergency treatment, indoor gas leakage: emergency shutdown, open the emergency air exhaust machine, cut off the total valve of boiler room, and report to the responsible departments, according to the natural gas leakage emergency treatment.

2. strictly regulate the industrial boiler gas design construction, uses the high quality boiler,burner, valves and other accessories, prevent gas leakage, strengthen management, regular inspection, must according to specification of the installation of gas leakage alarm device, and regular inspection. smoking and playing mobile phone in the industrial gas boiler room, no dumping any inflammable and sundries, real domestic demand the use of electric welding, gas welding operations, in strict accordance with the operation procedures, construction work by professional on-site monitoring, all those who enter the boiler room personnel are required to wear anti-static overalls.

4, when the industrial gas boiler gas leaks, gas concentration in the lower explosion limit before also need water spray extinguishing system protection. Using dilution water spray, the gas concentration decreased, can play the role of fire effect. Fire water and fire hydrant in good condition, especially in the cold winter, to prevent the pipeline freezing.
