low pollution fir tube boiler
The type of fuel gas steam low pollution fir tube boiler heat exchanger which heat exchanger fuel gas steam boiler are the following:? 1, shell and tube heat exchanger, the most widely used, the advantages of low cost, stable, moderate efficiency, cold pressure difference on both sides can heat. The disadvantage is that bulky, heat exchange efficiency is better plate heat exchanger; 2, plate heat exchanger, used in the thermal type tube slightly inferior, but the application of more heat exchange in the chemical industry, the advantage of small size, heat transfer efficiency. The disadvantage is the high price, the hot and cold sides of the small pressure difference is required; 3, volume of heat exchanger, substantially replace the two heat exchangers, seldom used, only the individual engineers also use sepia heart. Cost and volume of the tubular flat; 4, floating coil heat exchanger, a tubular outer shape slightly larger than the column, consistent with the principles of heat transfer tube type, but the efficiency is higher than the column tube below the plate. Since the service life is inferior tubular, is also substantially free of the use of such a heat exchanger; 5, soda heater, because there is no heat exchange process, so called soda heater. The principle is to use direct steam heating the water, so this process is used under certain conditions, rarely applied to the "heat" process, widely used for slaughtering, bathing, winter construction industry.
Carefully check the baby swimming pool oil-fired low pollution fir tube boiler fuel line if there is leakage, identify problems promptly. Ensure there is sufficient water in the oil-fired boiler, boiler dry to avoid the risk of occurrence. Do not place flammable items around the oil-fired boiler, should be preceded start the fan in use, running lights on bright indoor temperature controller, confirm ignition, after flameout function properly, start the boiler combustion. When the boiler can not start the fault lights, while the temperature display window display abnormal status code, when you restart 4-5 times still does not start, please contact the manufacturer or dealer for repair as soon as possible. 2. In the course should pay attention to:
Coal Pulverisers grind the coal to a very fine powder to make it burn easily. Pulverisers have steel rollers or steel balls which crush the coal between them into a fine powder. This powder is easy to burn. Coal contains moisture. Hot air form the Primary Air Fans dry the coal in the pulverisers. This makes the burning easy and efficient. This air also carries the dry coal powder from the pulverisers to the burners in the low pollution fir tube boiler furnace.In the burners the coal powder is mixed with the required amount of Combustion air and burned in the furnace.
Our paper packaging industry from the beginning of reform and opening up to today, we used 37 years to basically build a modern industrial system package. Bring a new era of paper packaging industry is a complicated international environment and arduous domestic reform, development and stability of the new normal, paper packaging industry is facing enormous challenges.
