Boiler design efficiency in the engineer design phase, and in general, the actual operation and the initial design thermal efficiency are similar. For example, oil and gas furnace efficiency is greater than 92%, and circulating fluidized bed boiler efficiency is usually higher than 88%. However, boiler efficiency is not fixed. If your equipment is operating at less than design efficiency, then measures can be taken to improve boiler thermal efficiency.
Fangkuai Boiler Company replied: in case of quenching, the fuel supply of the furnace must be cut off immediately, the electromagnetic valve for gas supply (oil supply and return oil) will be closed, and then the fuel supply valve for each burner shall be closed. Operate quickly so as not to cause a vicious risk when fuel continues or resumes supply. At the same time, find out the causes of boiler quenching, remove the found faults, and make preparations for restarting.
New Year period, Tongchuan City, Shaanxi Province seized by special pressure class inspectors seize the time, nonstop, through the tireless efforts have seven working days, the time limit runs successfully completed the Tongchuan city water quality testing and inspection work hundred sets of heating 10 bar propane fire boiler budgets.
In recent years, with the state-owned enterprises "three for one industry," the pace of the transfer of a separate depth step by step, in 2019, Tongchuan City Gas Co., Ltd. and Tongchuan Mining Co., Ltd. together for the original Tongchuan Coal mining companies and construction companies and their subsidiaries heating boiler units of unified management, are responsible for heating in winter work Yintai District and Wang Yi district within the city limits and nearly 30 residential units.
After receiving the application of these reported that construction of heating boilers, special prosecutor of the city leadership attaches great importance to immediately convene all pressure classes held inspectors "to ensure safety, promote harmony" will mobilize, deploy test the backbone of the boiler units get together and reported in accordance with inspection, quantity, wide distribution and other characteristics, develop a reasonable and effective inspection plan, centralized arrangements for the inspection of boiler units, inspectors have extensive under the jurisdiction of the Meiyuan district, dragon community, nearly 30 residential and hospital infrastructure companies run first-line heating boilers, boiler to run one by one test, carried out investigation and security risks, all currently in operation has successfully completed a water quality testing and inspection of boilers, boiler inspection a total of 101 units, 90 water samples boiler. In the access to information process safety management of the outstanding problems that exist in the use of boiler units, in accordance with the relevant regulations and safety requirements of technical specifications, targeted proposed guidance. During the inspection the boiler, for general questions, on-site supervision and the use of units of the rectification. Meanwhile, the inspection found two Royal River Area of boiler pressure parts leak is still sick to run for the safety problems on the spot requires the use of units to stop using the site issued a "special equipment inspection and opinions notice" to use the unit under and timely reported to the Council and served on equipment safety supervision departments seat safety supervision departments to actively supervise the use of the unit for rectification, at present, the use of hidden problems rectification units have been completed, the re-examination confirmed that security risks have been eliminated, effectively guarantee the safe and stable operation of the boiler .
Fuel gas 10 bar propane fire boiler budget heat losses are mainly chemical heat loss q2 and q3 loss of incomplete combustion heat loss q5. Exhaust gas boiler q2 loss is generally about 5 to 8 percent, chemical incomplete combustion loss of about 0.5% q3, q5 heat loss of 1% to 3%. Because almost no ash after combustion of the fuel gas, and no mechanical incomplete combustion of solid fuels and, therefore, no need for oil or gas boiler counted mechanical incomplete combustion ash heat loss and heat loss, i.e., q4 = q6 = 0. In all heat losses, heat losses q2 represent an important proportion, 70% to 80% of the total loss. Therefore, the main heat losses of fuel gas-fired boiler flue gas heat loss is q2.
