Coal fired chain grate boiler has DZL coal fired chain gate boiler and SZL coal fired chain grate boiler for sale. Coal fired chain grate Boiler is consisted on two major parts, the upper main body and lower grate part. The Upper main body part including two drums, water tubes, steel structure and packing sheet, all of which will be mounted in workshop.

What is considered to meet the criteria of a good gas boiler it?

First, manufacturing materials

Shandong Mining Group in the six months after the boiler use, users submit a report to our company, our company started in 2017 using WDR0.5-0.8-Ⅱ electric fast Boiler Co., Ltd. of heating steam boiler. Large output, stable and reliable, high degree of automation, simple operation, do especially in terms of security is in place. After-sales service is very timely response to our technical consulting reply quickly and accurately. Whether it is party party products or fast fast service. My company is very satisfied. --customer feedback

The problems in 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.
