big size energy save steam boiler

The problems in big size energy save steam boiler operation and the start-up of magnetic driven centrifugal pump will encounter many problems, among which the main problems are low temperature corrosion, slow exhaust speed, steam and water supply pipe damage and so on. The low temperature corrosion occurred on the low temperature heating surface of steam boiler has several main points: chemical corrosion and electrochemical corrosion. These two kinds of corrosion occur basically on the wall at lower temperature than the acid dew point. Ash deposition on the heated surface of evaporation can sometimes accelerate corrosion. The reasons for the slow exhaust rate are as follows: outlet filter core obstruction; too small cross-sectional area or long pipeline of piping; filter mesh blocking at the inlet end; reverse stop The valve won't open. Solutions to this type of problem: replace the outlet filter core, replace the larger cross-sectional line, or shorten the distance of the line; clean the filter and install an air filter at the inlet; check the spring of the reverse stop valve. In addition, steam boiler is easy to appear steam, water supply pipe damage phenomenon: when the pipe leak slightly, make noise, insulation layer wet or leakage steam, dripping water. When the pipe blasting, make a significant noise, and spray steam, water. The change of steam or feed water flow rate is abnormal, the blasting site decreases before the flow meter, and after the flow meter, the flow rate increases. A drop in steam pressure or feed water pressure. When feeding jellyfish tube blasting In 2000, the water level of the operating furnace dropped. The main causes of these phenomena are: steam pipe overtemperature operation, creep expansion beyond the standard or running time too long, metal strength reduced. Steam pipe heating pipe is not sufficient, resulting in serious water shock. The poor quality of water supply results in corrosion of pipe wall. The local scour of the water supply pipe causes the wall of the pipe to be scrubbed. Abnormal operation of the water supply system, excessive pressure fluctuations, water shock or vibration. Bad installation, manufacture, material and welding. The solution is: if the water supply pipeline leakage is slight, can maintain boiler feed water, and does not expand the fault quickly, can maintain short-term operation, put into the spare boiler as soon as possible, if the fault is added Drama, a direct threat to the safety of personal or equipment, should stop the furnace. If the water supply pipe blasting, we should try to detach the faulty pipe section from the system as soon as possible, and if it cannot be unlined and unable to maintain the drum water level, the furnace should also be shut down. If the steam pipe leakage is mild and does not enlarge the fault quickly, it can be maintained for a short period of time and put into the spare boiler as soon as possible. If the failure aggravates, it should be shut down if the failure directly threatens the safety of the person or equipment. If the boiler steam pipe blasting, unable to supply steam or direct threat to the safety of persons and equipment, should also stop the furnace. In the case of steam pipe blasting, an attempt should be made to unlist the faulty pipe segment from the system as soon as possible.

Application pressure hot water boiler sure they know what local initiatives have to opt for a professional operator to take care of, although now pressure hot water boiler has been reached will be fully automated intelligent control, but the operator on duty is still necessary, like to be able to quickly detect when the unexpected danger, it can lead to more serious reduce wear and tear, to guard against danger. Application hot water boiler fuel gas-fired boiler need to understand what matters | fuel boilers | big size energy save steam boiler Environmental Equipment Co., Ltd. We are definitely initiative to choose the person responsible for senior guard, even if today's oil hot water boiler has to reach intelligent automatic manipulation, but Head of duty or important, so you can quickly detect when unexpected problems before they can lead to more severe prevent wear and tear, to prevent accidents caused.

We produce big size energy save steam boiler is a very important part of the device, this provides a quick way to our gas steam boiler, after use, we found an excellent energy-saving effect boilers, flue gas discharge temperature is lower than the previous boiler equipment many, in line with national environmental provisions of the boiler equipment. --customer feedback

10 tph WNS series condensing gas-fired big size energy save steam boiler project for agriculture industry

Confronted with the increasingly severe environmental protection policies, ZOZEN has made progress in the research and development of technologies in recent years. WNS series gas-fired boilers with features of high efficiency and low emissions are preferred by the industrial boiler market. This series of boiler uses a radiant heating surface to increase the heat transfer coefficient. Besides, the boiler adopts high-efficient threaded flue tubes to slow down the flue gas flow rate and fully absorb heat. In addition, energy-saving devices are equipped at the tail of the flue to increase the thermal efficiency to above 98%. The efficiency is superior to international energy efficiency standard. Moreover, the advanced low NOx burner greatly reduces the emission of NOx to 30 mg/m. The ultra low emission provides guarantees for clean production and sustainable development of enterprises.

The hotter the heat exchanger the more heat you get. Down sizing nozzles may give higher calculated efficiencies but in most cases they give less delivered efficiency. The only time lowering the nozzle size could save is if the bigger nozzle was firing lousy or set up bad. 2.5gph instead of 6.5gph has to be costing 25% to 35% more energy.
