What is the use of a boiler in the paper industry?
The steam produced in the coal fired steam boilers is used to cook wood chips (along with the cooking chemicals). Steam is sent to dryer cans or Yankee dryer to remove the water from the sheet that the drainage, vacuum, and mechanical pressing sections of the paper machine can't accomplish.The steam from the boilers is also used throughout the mill in heat exchangers, steam-traced piping, stock chests, etc.
Learn fired vacuum hot water boiler price vacuum hot water boiler is a safe and reliable boiler varieties, developed since 1975, gradually became popular worldwide. Also for his safe and reliable operation, long life, adaptability, and efficient energy-saving features, the annual market share has gradually increased. Vacuum hot water boiler furnace divided into two parts; the upper half portion of a vacuum chamber (vacuum vapor chamber), which is provided with a tubular interior space of the vapor - water heat exchanger for heating circulating water flowing through the heat exchanger . The operating principle: vacuum hot water boiler is running, the negative pressure in the vacuum furnace body heat medium water absorbs heat energy released by burning fuel, Boiling water circulating system encounters a stainless steel heat exchanger of the low temperature steam, low temperature steam rises, heating recycled water to users for heating or hot water. Itself is cooled steam condenses into water droplets fall to the surface again after the heating medium is heated, thereby completing the entire cycle. Heating medium water constantly in the body with a closed circulation heating evaporation == == == heat medium condensed water, condensed water without added thus, no danger of burning air. Vacuum hot water boiler using soda condensation heat, all heat exchangers operating condition, soda condensation heat transfer coefficient is the highest.
For a long time, the boiler and burner are attributed to two different sectors each R & D re-combination, but the overall performance of the gas boiler, there is a qualitative impact. Fang fast R & D team after two years, estimates adjusted 300 times, breaking the status quo burner and boiler production separate, optimized depth coupled combustion system and heat transfer system architecture, combined boiler and combustion system, combustion system and successfully developed the depth of the heat transfer system coupled "Euromonitor θ5", so that gas-fired boiler into a complete energy system, to achieve a qualitative leap. "Euromonitor θ5" additional air pre-heater, cold air through the heat exchange tubes and the body opening for the flue gas countercurrent heat exchanger, the exhaust gas temperature is lowered while saving fuel; using a condenser, economizer flue gas heat recovery, thermal efficiency of the boiler can be increased by 10%; the use of FGR flue Gas recycling technology and Ultraten wing technology, improve heat transfer efficiency, emissions of nitrogen oxides emissions standards in line with domestic cities.
Vacuum gas boiler low water level is broken down to produce how to do 1, vacuum gas boiler water level there is not normal. 2, the water level controller has no problem. 3, low water level control tube stuck. 4, China Unicom cylinder tube blockage due to the formation of scale vacuum gas boiler must do what several environmental flow gas boilers | oil-fired boiler |? Environmental Equipment Co., Ltd. steam boiler coal-fired boiler must do desulfurization dust, vacuum gas boiler as long as it has no water purification, treatment? vacuum gas boilers are environmentally friendly facilities, smoke no need other treatment. Involved in water purification, do not know which side are you referring to? Vacuum gas boiler feedwater sure to go through the soft water, avoid vacuum gas boiler scale formation. If the sewage discharge, simply lowering the temperature, the supernatant can be directly discharged. So, vacuum gas boiler without environmental protection facilities.
