Measures food factory gas boiler fire prevention measures which have food factory gas boiler fire prevention measures which food factory gas boiler fire prevention have what? For food plants are some dry goods. If the improper use of the boiler, is likely to cause a fire. In this case, that will cause great losses. So, for food plants, it must be for measures to prevent fires do carefully. Otherwise, if indeed there is a fire, then the loss caused by the food factory is immeasurable. 1, fire prevention measures (1) when food factory gas boiler ignition before combustion, as in the gas boiler has been filled with combustible gas remaining, so before combustion, to be launched first delivery, induced draft fan forced ventilation 5-10 minutes, plenty of gas replacement in the furnace, the eradication of combustible gases in the furnace to boost the normal combustion, a combustion burner from scratch unsuccessful demand, must be ventilated before combustion to the hearth again, plenty eradicate combustible gas. When selecting manual burning, manual and commissioning is difficult to ensure accuracy, according to the rules of supervision regulation, gas boiler active protection device to device, including active combustion, flame protection, burning and automatically adjust the necessary proactive alerts protective equipment. (2) When the furnace temperature is low or when wetter, difficulties due to combustion, the need to take appropriate measures to preheat the furnace. (3) in the intake pipe in front of combustible gas nozzle, the device should the pressure gauge. (4) If the calm flame, the combustible gas is fed immediately discontinued, only for air, the ventilation, then the combustion operation. (5) To prevent the onset of bursting gas boiler during combustion, it is necessary to check before the gas pressure in the combustion in the intake pipe, when the pressure to meet the requirements, then the furnace was purged using a blower, eradication explosive mixture in the furnace. Should strictly abide by burning first combustion gas after opening the guidelines. 2, food factory fire prevention measures (1) prevent gas boiler work off the fire: combustible gas burner output is too large, the flame will disengage burner, too many episodes of incomplete combustion of the combustible gas, a lot of memory product in the furnace blast mixed gas, there is a risk of explosion at any time. Therefore, we should pay attention to fire off phenomenon, specific measures are: a, stable embodiment of the flame; B, to adjust the air-fuel ratio near the theoretical mixture ratio; C, artificially increased combustion speed; D, adhere to stable pressure of the combustible gas; E, reducing the discharge velocity of the fuel. (2) prevent tempering: flammable gas output is too small, the flame will be retracted into the combustor, the boiler operation and stable flame without flame. After the moment continuously into a combustible gas, the combustible gas reaches the limit blasting, blasting rattling. Prevent tempering phenomenon approach are: a, the minimum discharge rate increase; B, it is necessary that the fuel discharged from the nozzle velocity greater than the burning velocity, i.e. adhere to the furnace pressure (3) into the post-combustion process until a stable condition , the supervision to be good combustion conditions, pay attention to conditioning the combustion air flow, stable combustion pressure, a stable flame can burn. (4) to cut chimney smoke, the Mars and pollute the environment, flaming chimney should be comprehensive treatment, such as smoke and dust removal equipment and Mars quell equipment. (5) in normal operation, can not pay attention to cold and hot temperatures, to prevent the onset of bursting. 3, to prevent severe food shortage in gas-fired boiler plant boiler severe lack of water or dry out somethin 'somethin' is a kind of chemical, oil-producing boilers throughout the attack. Fireman to supervise closely the timing of the water level in the boiler operation time in Sheung Shui, the water level indicator to check whether a job is often normal, the sewage discharge dirt cleaning process.
To get gas boiler energy-saving operation, the measures to be taken in recent years, the national ambient air quality for more stringent supervision, the country more regions have entered an important period of development of environmental governance. Boiler to provide energy as the main force, the regulatory environment is the main object of regulation. With clean gas boiler, environmental performance advantages, widely used in all walks of life. This paper made a brief discussion on the gas boiler in the operation of existing problems, as well as the experience of the energy-saving operation. A gas present in the energy-saving operation of the boiler main contradiction required for combustion, in addition to combustible material gas, together with sufficient oxygen, oxygen is mainly from the air. In addition, a sufficiently high temperature is essential. In general, the combustion conditions comprises: a proportion of combustible material, oxygen molecules and a certain temperature. The energy conservation law, the release of gas entering the boiler system total energy q, should be equal to the total energy flowing from the boiler system comprising a furnace heat absorption water q1, bad water absorption cycle heat q2, loss of incomplete combustion Q3, Q4 heat, smoke q5. That is: q = q1 + q2 + q3 + q4 + q5. We can see from the above equation, it must be reduced in order to achieve fuel savings Q3 loss of incomplete combustion, and heat loss due to heat q4 q5. Among them, heat losses q5 that is where the greatest energy loss, and most have a recycling value. To make full use of the energy produced by combustion of the fuel, it is necessary to minimize the exhaust gas temperature. However, reducing the exhaust gas temperature in the actual operation of the boiler will produce such a large amount of condensed water, causing corrosion to the boiler thereby shortening the life of the boiler. Boiler flue gas temperature is lower condensed water is greater, the greater the harm caused by the boiler. That is the lower the boiler flue gas temperature, lower operating costs, greater harm to the boiler, the higher the cost; the higher the boiler flue gas temperature, higher operating costs, but less harmful to the boiler, using the lower the cost. This contradiction is the main problem, GAS boiler operation impact. Second, the method of reducing the exhaust gas temperature of the boiler route 1 increased tail heating surface, i.e. the installation of the boiler economizer (or condenser) to reduce exhaust gas temperature. After entering the boiler economizer outlet flue gas from the rear of the boiler, the flue gas absorption part of the heat, out of the low-temperature economizer flue stack emissions reentry heat boiler economizer heating boiler return absorbed, thereby improving the return water temperature, while reducing the exhaust gas temperature and improve the thermal efficiency of the boiler. Boiler economizer arrangement there is a significant advantage to improve the economizer return temperature of the boiler, can significantly reduce the generation of condensed water boiler, a boiler body for protection, but the condensed water economizer itself is very large , so the corrosion generated is very large, but with the energy-saving boiler is arranged separately, leakage and other conditions of corrosion maintenance costs to replace the energy-saving device is far below the cost of running the boiler. 2, the exhaust arrangement (flue gas) heat recovery. Exhaust heat recovery from the flue gas passage to increase spray tower, heat exchange by spraying water mixed with the flue gas, a large amount of heat carried away by the fumes spray water, reduced exhaust gas temperature, high temperature spray water is pressurized by the circulating pump through a heat exchanger or other heating boiler return mechanisms, in order to achieve recycling of flue gas waste heat of exhaust gas temperature is reduced, saving energy and reducing the running cost and the fuel. Than the exhaust heat recovery economizer much better energy-saving effect, even some devices may be the flue gas water vapor latent heat recovery. But the exhaust heat recovery unit investment, more equipment, additional operating costs also, the failure rate is high. The economizer is simple and reliable, no mechanical component failure rate, operating costs are zero. Which method is more suitable for specific use, but also to all of you to choose according to their own characteristics situation. Third, reduce condensation water boiler operation measures by increasing heating surface or rear of the boiler flue gas heat recovery unit, may be fully recovered heat loss boiler. Improve when the boiler boiler load, reducing the number of operating units to minimize the situation of low load boiler running multiple online. Boiler flue gas temperature as high as possible, as much as possible to avoid the situation boiler produces condensation water appears to reduce the corrosion of boiler condensate, to extend the life of the boiler. Carried in the flue gas, the unused energy to the heating surface of the tail to be recycled, which saves the cost of using the boiler, but also save operating costs of gas consumption, thereby achieving energy saving purposes, increasing the economic efficiency of enterprises . With the continuous improvement and the rapid development of industrial level of our national economy, gas boiler applications more widely. Especially in recent years, air quality has become a major environmental problem the government is particularly concerned, in the promotion, use and development of a gas boiler future period will enter a new phase. Study and solve the issues affecting energy-saving operation of a gas boiler, and constantly improve the operating efficiency of the gas boiler, saving energy, reducing emissions, businesses and society as a whole will bring enormous economic and social benefits.
