Steam Boiler For Food Industry Production
Group multiple departments quality systems, technology department, production systems, development systems, with the assistance of outside experts, please, to overcome the difficulties, overtime, and fulfill all the preparatory work. Assessor staff often give up personal time off from work carried ASME study and training, frontline staff overtime for practical operation of the exercise. All those involved in the trial personnel in the company "professional life, work lean" under the guidance of the core values of continuous fighting, the various problems couplet review group proposed were closed, one-time passed the ASME certification.
Hazard Ultra-low-load operation of the boiler What? Coal-fired boilers is 70% to 100% of rated load, fuel gas boiler 60% to 100% of rated load. Ultra-low-load operation is deemed to run below this range. Then the ultra-low-load operation of the boiler harm What? Fuel gas-fired boiler factory and you came to talk about it! 1. difficult to guarantee the quality of steam: with the boiler load decreases, the steam temperature and humidity will be affected, in particular for a boiler with a superheater, boiler load is reduced, resulting in reduced exit steam temperature is difficult to maintain rated steam temperature, steam quality deterioration. When the superheated steam temperature drops below nominal, soda heating surface system conditions will enter the danger zone, when the load is low zui called technically permissible load. 2. boiler water circulation decreased reliability: fuel gas circulation usually natural circulation. Ultra-low-load operation, because a small amount of fuel into the boiler, the temperature drop across the furnace, the heated water wall weakening, boiler water circulation flow rate will be reduced, reliability is lowered circulation. 3. The rear of the boiler heating surface acid corrosion aggravated: Ultra load operation, the furnace temperature was decreased to varying degrees departments, the exhaust gas temperature will be reduced. It is easy to make the heating surface of the metal wall of cryogenic temperature below the temperature of the vapor *** sulfuric acid, sulfuric acid vapor condensation heating surface will be at a low temperature, resulting in low corrosion of heating surfaces. In summary, fuel gas-fired boiler ultra-low-load operation this issue, we can not be ignored.
Recycling coal-fired steam boiler for food industry production type selection and steam: Steam boilers, if the fuel is coal, then on the specific species, should be how to choose? This kind of boiler, garment factories used, which has a specific purpose? In addition, the steam boiler on, what the problem is we do not know and understand? Ask these questions, its main purpose is to be completely resolved, so that we can be deepened in the familiarity of the steam boiler, so that would not have been at a standstill. 1. coal-fired steam boiler steam boiler in which one of its kind in the coal, what should I be selected? Specific types of coal fired steam boiler, in which the furnace is to look at the main selection and specific requirements, if it is a manual type, and has a dust removal system, then, should be used bituminous high calorific value, no dust removal system, then , it is for the high calorific value of anthracite. Further, if a mechanical grate, which corresponds, for the bituminous coal of low calorific value.
Ignition gas steam boiler for food industry production should pay attention to what is the use of gas steam boiler before us is to do the work of an ignition device, so as to provide for the heat needed, therefore very important, but at the time of ignition are a lot of issues need attention the only good attention to these in order to fully guarantee the final results, gave you pay attention to the following points about the firing, so there is not any problem when in operation. the first is to pay attention to good gas steam boiler inspection, whether internal or external device, we are working to do before ignition checks in order to determine the normal ignition when no dangerous goods, so as to ensure there is no problem in the operation of the process followed prior to ignition for some security parts we are good to check to ensure that all components are in good working condition, so that when the ignition is in order to achieve a better protective effect, there would be no danger happened, and we at work be sure to check good, so we can more fully guarantee the final ignition safety A. When we ignition of a gas steam boiler must pay attention to good account the above considerations, so there is no problem.
