Natural gas boiler flue gas temperature requirements? Normal exhaust gas temperature of the boiler in about 180 ℃, the higher the exhaust gas temperature is low thermal efficiency of the boiler. Fast side gas produced advanced condensing boiler technology is added, the high temperature flue gas condenses, releasing heat again, while the exhaust gas temperature is also reduced, the following may be less than 120 ℃. From the energy point of saving money, it advocates the use of condensing gas boiler, energy-saving than ordinary gas boiler about 30%. Now there is no national regulations on exhaust gas temperature, gas-fired, but the above explanation, you know, the lower exhaust gas temperature, flue gas heat utilization fuller, higher fuel efficiency, higher thermal efficiency of the boiler, and finally to save energy to save money.

Recently, in Qinghai Province Jigzhi County Market Authority carried out a special inspection of boiler safety within the county, mainly in order to further strengthen the special equipment safety supervision, investigation and potential risks.

County Market Authority was held on June 8 special meeting to make arrangements for this special inspection work; the meeting, Secretary of this special inspections put forward specific requirements: Either the county government and relevant departments in accordance with the superior, all in the area to check boilers, boiler and disabled to look back, to verify the implementation of the rectification; the second is to designate a person to carry out checks to ensure that this special inspection into effect, produce results; the third is to check violations found to be severely dealt with according to law.

Subsequently, according to the spirit of the meeting, Jigzhi County Market Authority Board redoubling its efforts to carry out special inspections. 5 out of law enforcement officers were examined using 10 units. The county has been reported to stop the boiler After registering with and eleven inspection and verification. Focus on checking whether the boiler inspection, whether the registration, check whether safety accessories in place, whether fireman certificates and other issues, focusing on correct pressure boilers, waste heat and pressure tanks and other equipment as well as the use of pressure boiler overpressure operation and other illegal operations behavior, found hidden among all checks for disposal in accordance with law, to ensure the safe operation of the boiler county.

Next, the county will further increase the pressure in the boiler with supervision and do routine inspections and safety management, strengthen the use of units to pay a return visit found the problem of checks put in place to promote the use of the unit responsibility, and earnestly safeguard the life and property Safety.

Area gas boiler heating gas boiler accurate measurement method is now occupied most of district heating, but heating in the heating area, indeed never specifically talked about today Xiaobian find some relevant content to share to you, you can use to confirm. 1. Gas boiler heating area thickness measurement method. Thickness measurement method using a thickness gauge that the wall thickness of the gas boiler heating surface area wear or corrosion thinned tube, the tube is used to determine the degree of thinning. Method for checking the thickness measurement of various heating surface, particularly suitable for checking internal heating surface tubes corrosion. 2. A gas boiler heating area vernier caliper measurement. With a vernier caliper to tubes of the heating surface is easy to wear or swelling burn site was measured, in practice, typically superheater or reheater tube wall temperature measurements up areas, to verify whether the tubing expansion thick, wear or corrosion. Significance with a vernier caliper to easily burn the heating surface tubes wall temperature measuring swelling in that the heating surface tubes and the measurement site recorded measurement results, the values ​​obtained for the measurement at the same site compared with the next overhaul, gas heating surface tubes to determine readily fired boiler burning site bulge swelling tendency, as the basis for future maintenance. 3. A gas boiler heating area of ​​the spacer caliper measurement. Spacer caliper is in accordance with various specifications of the tube heating surface, a number of manufacturing a caliper fixed dimensions, the size of each pipe, the two or three different sizes caliper according to its production of pipe material . The caliper is the maximum value of the maximum thick carbon steel pipe expanding the outer diameter of not more than 3.5% or the maximum expansion of crude steel pipe does not exceed a predetermined outer diameter and 2.5% prepared, carried out with the maximum pipe diameter measurement caliper according to the material of the tube it can be determined whether the tube exceeds a predetermined expansion crude. The minimum caliper is the maximum amount of thinning of the tube wall thickness of the pipe does not exceed 1/3 of the fabricated, for the pipe diameter with the minimum calipers measured, based on the tube exceeds a predetermined amount is thinned. Employed, spacer caliper measurement exceeds a predetermined heating surface tubes, with high efficiency, high inspection speed, reduce labor intensity inspection personnel and so on. The maximum caliper is used to check gas boiler superheater or reheater tubes exceeds a predetermined expansion crude measurement tool, and the minimum caliper is used to check the superheater, reheater, economizer, or wear, corrosion exceeds a predetermined measurement tools.

Industrial boiler stoker boiler overpressure personnel, Water Shortage Accidents treatment of industrial boiler stoker boiler overpressure personnel, Water Shortage Accidents treatment of industrial boiler stoker boiler overpressure personnel, processing method 1 Water Shortage Accidents, industrial boilers appear overpressure accident boiler overpressure accident is due to the actual operation of the boiler actual pressure value exceeds the maximum working pressure caused. Boiler overpressure accident is an accident the most common accidents. Overpressure characterization: the boiler is running, when the pressure in the boiler is too high, the air pressure will be significantly increased, exceeding the safe working pressure of the boiler, boiler safety play a proactive action; boiler overpressure alarm will issue a warning signal; steam temperature rising Wait. Common causes of boiler overpressure are: gas fault does not operate normally with gas; valve failure, equipment failure alarm; relates to a boiler because defects result buck during use, the cross-sectional area of ​​the exhaust valve is not adjusted , still use the original terms of safety valves. Processing overpressure accident. Found boiler overpressure should be reduced combustion; if the boiler safety law does not work, can take artificial exhaust, or located vent valve on the boiler open for exhaust, to adjust the pressure of the boiler; maintaining an internal boiler water level is normal, reduce oven temperature; the oven before deciding to stop or resume operation, check the cause of the boiler overpressure and damage the furnace. 2, industrial boiler water accidents occur during use of the boiler, the boiler water shortage accident was mainly due to the boiler water level below the safety level. Boiler water often leads to additional boiler superheater heating surface tubes cause deformation even wave train; mouth off or leakage; boiler wall is damaged. In the use of the boiler, the boiler water accidents can not be properly resolved, will often bring very bad consequences, causing serious damage. During the accident boiler water treatment, we must first determine the severity of the accident boiler water, and then select a reasonable solution. When the boiler water accidents judge, the method used is called the water. The specific workflow is put cock open water table, water vapor union and even the water pipes were flushed, the union says is the subject of steam cocks closed, while closing the drain cocks. If the water level in the table who is appears, the boiler water shortage accident as minor, if there is no water in the water table appears, the water level has dropped to even lower water level or water pipes, which shows a serious lack of water boiler accident. Sheung Shui to be a slight lack of water in the boiler immediately when an accident occurs, to ensure that the water level in the boiler at normal levels. If by Sheung Shui, the water level in the boiler water level is still not back to normal, we need to conduct a comprehensive inspection of the boiler. When the boiler severe lack of water, the boiler must stop work.
