11t oil fired hot water boiler steam boiler
Gas and coal-fired steam boiler steam boiler compare what are the advantages of (1) from the traditional economic point of view and our energy structure, coal-fired boilers due to the low one-time investment costs of popular people favored, especially in the rich coal resources , green area less demanding people prefer to select it. But in resource-poor coal, coal prices are not low areas of oil, gas and coal compared to a certain competitiveness. Another reason people like coal stove is easy to operate. But coal-fired boiler pollution: waste, emissions, waste water, "three wastes" and taste, governance Yijiao difficult (especially desulfurization, coal-fired boiler desulfurization technology currently has achieved some results, but the high investment costs, complex operation, covers an area of large), from the social perspective should limit the use of coal-fired boilers. Soot emissions (2) oil-fired boilers, although lower, but its emissions of harmful NOX, SOX gases are causing "photochemical smog" and acid rain culprit, you want to be like governance as coal-fired boiler soot emissions control. (3) gas boiler has a small footprint, less pollution emissions advantages, but also the cost of the boiler room is not set up, the use of natural gas fuel prices, operating costs lower than oil-fired boiler. (4) not only set in three furnaces comparison, gas boiler lower costs and operating costs, and its social benefits are incomparable. Natural gas is the cleanest fuel, is the least polluting fuel emissions, gas-fired boilers will be the development trend of boiler final.
The temperature difference between the wall surface of the vertical steam boiler steam is generated during the vertical steam boiler generates steam, and pressure in the heating, when the temperature is higher than the outer wall temperature of the inner wall, the wall temperature is higher than the temperature of the lower wall, and wall thickness of the vertical bubble there is a temperature difference between the walls, i.e., the inner wall temperature of the bubble is higher than the temperature of the outer wall, the wall temperature is higher than a temperature lower wall, an outer wall and inner wall temperature is higher than the temperature of the inner wall temperature is higher than the outer wall temperature, the wall temperature is higher than the temperature of the lower wall , the wall temperature is higher than the outer wall temperature, the wall temperature is higher than the temperature at the wall, the inner wall temperature is higher than the outer wall temperature. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass 11t fired hot water boiler steam boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. In order to prevent excessive thermal stress, it is necessary to slow the vertical steam boiler booster. Vertical steam boiler ignition and boosting process conditions steam parameters, each component level and also changing. Therefore, in order to effectively prevent the occurrence of abnormal conditions and other hazards, it is necessary to arrange closely monitor vertical steam boiler various instruments directive professionals change. Since the vertical steam boiler water temperature continues to rise, the metal wall temperature of the bubble and the evaporator heating surface begins to rise at any time, it is necessary to pay attention to temperature and thermal stress of thermal expansion of the bubble, since the bubble wall thickness is relatively thick, so vertical the main problem in the steam boiler heating thermal stress. At the same time, also considering the overall thermal expansion problems, especially vertical tube steam boiler heating surface, since the wall thickness, length of problems in the process of heating the whole of the problems of thermal expansion, it should also be noted that the thermal stress. Prevent inadvertent failure caused.
Our emphasis on increasing green, local governments also boiler operation produces nitrogen oxides and smoke emission requirements become more stringent. Fast boiler followed by the national trend of development, deepening of cleaning boiler product design and development. Lulu as a representative of business development of the national beverage, and hope to find a set of boiler energy conservation and clean in one, for drink production process of fermentation, sterilization, drying, curing and other processes. After many visits and market research, in October 2017 and entered into boiler fast boiler purchase contracts, purchase two 10 tons of steam and a whole 20 tons of steam condensing steam boiler. The two sides this cooperation is the other quality fast condensing gas boiler highly recognized, has proved a powerful strength fast boiler in the boiler production and service of gas condensate from the side.
Solutions and prevention of gas oil-fired boiler flameout Today we'll resolve what about gas fuel boiler flameout solutions and prevention fuel gas-fired boiler flameout Solution: First, the furnace pressure gauge indicates the value suddenly increases, the furnace black can not see the flame, burning furnace sounds disappear, extinguishing the flame supervision devices emit a signal; the temperature dropped sharply atmospheric pressure, the water level dropped after the first rise, and so are flameout phenomenon. Auxiliary flame caused by an accident, such as a fan, blower power interruption, there is an accident signal emitted; fuel supply as a result of intermittent, the boiler is oil or gas pressure drops to zero, only a single burner flame, the furnace may also be thrown skew central flame extinguished burner pressure change; as a result of the fuel supply interruption, the extinguished burner pressure or hydraulic indication may drop to zero, and the fuel consumption, the gas pressure is increased other operating burner. Causes gas boiler flameout are: sudden increase in gas pressure caused from the fire, the solenoid valve malfunction the gas supply interruption, the gas composition has changed so much moisture content is too high and so on. Blower, fan failure, the load is too low furnace pressure is too large excessive leakage and other excessive wind, so that the furnace temperature is too low can also cause the boiler flame. Cause misfire has oil-fired boiler: oil pump failure, the oil surface is exposed inhalation tube, clogging of the oil filter or oil supply pipe, a solenoid valve malfunction or misoperation caused by oil running intermittently. During transport the fuel with steam by heating water; inappropriate position inhalation tube with the pumping of water; improper contaminated oil floating on the water; poor dewatering tank drain plug such that the fuel with water. After the explosion should be taken to prevent the furnace boiler flameout, it must immediately cut off the fuel supply to the furnace, and then block the electromagnetic valve of the gas supply valve to seal off the fuel supply to run the burner. When the action to be fast in order to avoid inheritance or restore fuel supply during operation, causing the furnace explosion. And identify the cause of boiler flameout troubleshooting find a good job and then start the preparatory work. Before starting the boiler should be enhanced ventilation purge, purge time is more than 5min, then procedures ignition. It is forbidden to send fuel directly to the high-temperature furnace without using an ignition spark ignition device to prevent furnace explosions. If due to fan failure caused when the flame should be quickly cordoned off the fuel supply line of each valve, with special attention because the valve is not tight blockade caused by leaking fuel. Ventilation and purging of the furnace and flue in accordance with the approach of an emergency shutdown. Ignition step by step in the recovery operation after the fan. Single burner flame burner only block the fuel supply valve, the burner off a small damper identifying and troubleshooting and then re-ignition by the ignition process. Boiler flameout of prevention: For oil-fired boiler should minimize the possibility of fuel transport, storage and handling of water in all sectors. Tank initiative measures should dehydration and dehydration on schedule. In any case, it should ensure the security of oil supply. The supply of oil and acceptance testing, cutting oil change when the master species. When a large change in oil types, varieties and the need for the oil tank to store the original varieties contaminated test to determine whether the same storage tank, to prevent the density and viscosity differences between a large number of decomposed oil mixed insoluble material, clogging oil pipeline. For the operation of the gas boiler should be closely monitoring the evolution of gas pressure, the timely processing of exceptions thrown up air pressure, ensure the supply pressure in the normal range. To always understand, repair gas composition, gas composition changes when large, to take the necessary adjustment measures on the boiler operation.
