industry boiler in vietnam

Gas hot water industry boiler in vietnam safe operation Code: People can not do without domestic water heating and gas hot water boiler, due to the special nature of the performance of the need to comply with strict safety operation of the Code. Then, gas hot water boiler needs to run how to protect their safety performance? 1, after carefully checking gas hot water boiler water supply, drainage, gas pipe fittings, safety valve, pressure gauge, water level gauge is sensitive Haoshi before work, make sure it is safe to operate. 2, with both hands to manipulate when Sheung hand to open the door of water, whereupon the other hand the water injector and valve open, water flows naturally into the furnace. When stopped, the steam valve should be closed first, then turn off the water door, switch and valve, the front face must escape in order to avoid accidents caused by soft drinks out. 3, gas hot water boiler in operation, to pay attention to all parts of the check, and observe whether the water pressure in the normal range. Fireman can not leave their posts without permission, when night work, avoid dozing off, but not allowed to sleep, to avoid accidents. Boiler blowdown, a class must be properly adjusted before the sewage water level, slightly higher than the normal water level of 2/3 of the standard, then the sewage. 4, the water level table class must be flushed once. Flushing, according to a predetermined program, the first closing valve and open the drain valve, flushing steam valve, when attention is blocked steam origin; steam valve is then closed, when attention is blocked antecedents water. Flushing valve, until the water becomes steam, some a little longer, in order to guarantee no false water level. Hot water boiler fuel gas safety checks must be carried out to prevent the presence of explosive materials in the fuel to prevent the risk of explosion.

To protect the economic development of enterprises, production safety running smoothly, according to Qingyang County in Anhui Chizhou municipal government air pollution control requirements, coal-fired industry boiler in vietnam inspection pull the plug on a regular basis in October 2018.

Qingyang County Market Supervisory Authority for the county a number of companies were visited research to understand the company's current production operating conditions and problems, start from regulatory functions, for enterprise development to provide quality services, reduce business costs.

Special equipment boiler pressure is high risk, than a regular inspection cycle must immediately stop using, but they are also necessary for the production of business equipment, once the shutdown enterprises will face shutdown. Looking at business owners anxious eyes and counties actively discussing with the city center expert special inspection, and according to regulations, to quickly determine a set of effective programs and promptly inform each enterprise.

Through contact with the surrounding counties and cities to understand the relevant units of the boiler fuel change fees and counties take the initiative and boiler companies approached agreed upon with the use of rehabilitation programs, a significant reduction in transformation costs. Up to now, Qingyang County has completed 12 boiler fuel change work, the cumulative cost of more than 60 million.

Features WNS type gas pressure hot water industry boiler in vietnam WNS What are the characteristics of the type of gas pressure hot water boiler which features WNS type gas pressure hot water boilers have what? Boiler by the boiler tubes, and double-wave oven can return flue composition mixed with the air to ignite the fuel rod electronic ignition burner, injection waveform burner, high temperature flue gas to the combustion chamber of the furnace two convection bank state, the sub-packets into flue economizer (optional), a boiler feed water preheater, while further reducing the temperature of the boiler exhaust gas, and finally discharged to the atmosphere through the chimney flue. WNS type gas pressure hot water boiler Features (1) the use of CAD computer graphics software to optimize the design to ensure good water circulation, small flow resistance. Heating surface heat transfer coefficient is fully optimized, high thermal efficiency. (2) Special Equipment Association of Henan Province drawing safe and reliable. (3) downstream of the body is a horizontal wet return all three structures, a large heat transfer area, the thermal efficiency is much higher than the normal center structures, (4) primary compression element is butt-welded to ensure the welding quality. (5) interpolation spoiler smoke tubes, high thermal efficiency; (6) furnace bile formation, the use of special materials to protect the furnace. It can also ensure that the water is clean and clean. (7) furnace open manhole, hand hole to facilitate maintenance; (8) burner equipped with imported Italian Baird burner valve group including filtration devices and leak detection devices. Combustion and good regulation performance, safety and efficiency; (9) with a dry boiler combustion apparatus, in order to prevent damage to the boiler water.

In addition to transforming the traditional industrial coal-fired industry boiler in vietnam into a natural gas steam boiler, the following natural gas steam boiler energy-saving measures can also be taken in the operation of the natural gas steam boiler.

1. Reasonable selection of the rated power of the natural gas steam boiler: According to the amount of steam needed in industrial production, the rated power of natural gas steam boiler and the number of boiler stations are reasonably selected. The higher the matching degree with the actual use, the smaller the exhaust loss, and the more obvious the energy saving will be.

2. Full contact of fuel with air: The optimum proportion of fuel and air can not only improve the combustion efficiency of fuel, but also reduce the emission of polluting gases, and achieve the goal of double energy saving.

3. Reduce the exhaust temperature of the natural gas steam boiler: The efficiency of the boiler is 85% and the exhaust temperature is 220? 230 ℃ when the waste heat produced in the exhaust gas is used to reduce the flue gas temperature of the boiler. The efficiency of the boiler is 85% and the exhaust temperature of the boiler is 220 ℃. The boiler efficiency can be increased to 90% by setting the economizer and so on, when the exhaust heat is used, the exhaust temperature is reduced to 140 °C and the boiler efficiency is increased to 90%.

4. Recovery of heat from boiler sewage: The purpose of energy saving of natural gas steam boiler is to raise the feed water temperature of pruriant water by heat exchange and utilize the heat in continuous discharge water.
