1 tonne h capacity waste heat boiler
Dongguan condensing steam 1 tonne h capacity waste heat boiler paper mill paper mill prices are now also required to respond to the government's policy of low nitrogen emissions, paper mill for the enterprise, in the procurement of the boiler must be to choose clean energy as fuel, as well as with the procurement condensing the steam boiler is also necessary. Not only can reduce emissions of nitrogen oxides, more critical it is possible to improve the thermal efficiency of the boiler, for enterprises to reduce operating costs. Recently, there is a paper mill in Dongguan need to purchase a condensing steam boiler for the production of the fast boiler advice, but also accounted for technicians need fast boiler manufacturers have tonnage required. After accounting concluded that the paper mill with steam condensing boiler 4 tons of Taiwan is to meet the production. The model is currently in the party fast price is around 500,000.
Operation of the steam 1 tonne h capacity waste heat boiler problem and start the process of magnetic drive a steam boiler in question and magnetic drive centrifugal pump will encounter many problems start centrifugal pump during operation, the principle of which have low-temperature corrosion, exhaust slow, steam and water pipe damage and other problems. It occurred in the low-temperature low-temperature steam boiler heating surface corrosion there are so few points: chemical corrosion, and electrochemical corrosion. Both corrosion occurs on the wall surface temperature substantially lower than the acid dew point. Fouling of the evaporator heating surface, and sometimes can accelerate corrosion. Slow exhaust reasons are the following: Filter outlet obstruction; cross-sectional area of the pipe line is too long or too small; the inlet side of the filter blocked; check valve open. Solution to this problem: replace outlet Filter replacement pipe cross-sectional area larger, the distance or length of tubing; clean the filter, a means at the inlet end of the air cleaner; check spring check valve. In addition also prone steam boiler steam, water pipe damage phenomena: the pipe minor leaks, beep, insulation or damp steam leakage, dripping. The pipe bursting, issued significant sound, and the discharge gas, water. Steam or water flow abnormal changes, blasting site before flow meter, the flow rate reduction; After the flow meter, the flow rate increases. Steam pressure or water pressure drop. When a water pipe burst, the water level dropped furnace operation. The reasons for these phenomena are: over-temperature steam pipes run, creeping inflation exceeded the standard or run too long, reduce metal strength. Warm steam pipe tube is insufficient, resulting in severe water impact. Poor water supply and quality, resulting in wall corrosion. Water pipe wall causing scour book locally reduced. Water supply system is not functioning properly, the pressure fluctuation is too large, the water impact or vibration. Installation, manufacturing, materials and poor welding and the like. The solution is: Such as water supply pipeline leak slightly, to maintain the boiler feed water, and soon expanded without fault, we can maintain a short run, put the spare boiler as soon as possible, if the failure increased, a direct threat to the safety of persons or equipment should be shutdown . Such as water pipe bursting, pipe failure should seek to splitting with the system as soon as possible, if not running out but can not keep the drum level, should be shutdown. Such as steam pipe leak slightly, when a failure will not expand quickly, we can maintain a short run, put the spare boiler as soon as possible; if the failure increased, a direct threat to the safety of persons or equipment should be shutdown. Such as boiler steam pipe explosion, not for steam or when a direct threat to the safety of persons and equipment, should be shutdown. The mother tube steam explosion, the splitting should seek fault and the pipe system as soon as possible.
How to reduce the exhaust gas temperature after 1 tonne h capacity waste heat boiler operation it?
1, the use of an economizer and a condenser
The safety inspection operations will be based on "regarding the development of 1 tonne h capacity waste heat boilers and industrial emergency notification equipment and facilities safety inspection of" (Wei Safety Office Zi  No. 23) documentation requirements, earnestly implement the regulatory responsibility, and actively carry out arrangements, combined with Cravens practical, clear pressure boiler safety inspection work content and division of tasks.
In conjunction with the National Health City welcome the review investigation work, based on their job functions, all members of the team to take the sinking line, full package by, Division linkage approach, focusing on whether the boiler to handle the use of registration, whether periodic inspection, workers who whether induction certificate, the safety valves and pressure gauges and other safety accessories boilers are using the site regularly check verification, the highest level gauge whether there has been a minimum level of safety markings for verification. 54 boiler region's 24 units were one by one investigation. Up to now, all 33 units in the boiler are in an examination period, in line with the requirements. It has two boilers to handle the deregistration, and 19 boilers have long-term disabled, is now urging the use of units to seize deregistered.
While actively step up publicity and training efforts, and send more professionals to communities, cooperatives were the main person in charge of safety knowledge of professional training, to explain the basics of boiler and check focus, effective universal safety knowledge, improve regulatory efficiency.
