What checks should be done before the gas-fired boiler starts?
Because gas-fired boiler is a kind of container equipment with steam and pressure, it is easy to cause accidents if the safety code is not followed in the course of operation, so, Gas-fired boiler operators must follow the rules and regulations to implement the relevant procedures and make good operation and shift records. The following is a high-stability gas-fired boiler manufacturers to introduce what checks should be done before the start of the furnace.
1. When checking the appearance and gas pressure of the boiler, when preparing to start the gas-fired boiler, the on-duty furnace worker should first do a comprehensive inspection, including the appearance of the boiler, the valves and the connecting parts, and then check the pressure of the gas. Ensure that the pressure value is within the normal range, not too high or too low, and that the gas supply valve cannot be opened until it is checked and confirmed to be normal.
2, check the water supply system gas-fired boiler when burning, there should be water inside, otherwise there will be danger. Therefore, before the stove is opened, the boiler workers should check the water supply system and see if the pump can supply water. If the water supply is not properly switched on, the exhaust valve should be opened and ventilated, knowing that the pump can start the water supply. Then open the valves in the water supply system.
3. Checking the water level if too much or too little water in the gas-fired boiler will have an impact on the safe operation of the boiler, it is very important to check the water level gauge well before the start of the furnace. Because the function of the water level gauge is to let the stoves know how much water there is in the boiler at the moment. Therefore, before starting a gas-fired boiler, it is necessary to see whether the position of the water level gauge is normal or not, and also to see whether the level gauge and color plug of the water level meter are in the open position, so as to avoid the phenomenon of false water level, and then to observe whether there is a shortage of water. If lack of water can manually carry out boiler water filling.
What are the key points of operation of fully premixed condensing boiler
When the condensing boiler is used, it adopts a special principle to make use of the way of water circulation to produce a certain heat exchange so as to achieve the desired purpose. Although the price of the integrated condensing boiler will not be too high, and the operation is very simple, and has good safety performance and so on, but in the process of operation, it is necessary to pay attention to the following points.
1, pre-service preparations for long-term non-operational or brand-new fully premixed condensing boilers, clean up the system with water before starting again, this is an extremely important preparatory work for condensing boilers. The operation of the docking will be of great help. And condensing boiler manufacturers remind you to start in the correct order, such as turning the circulating pump on before you can ignite it.
2, in order to control the details of the operation of the condensing boiler during its operation, in order to make it work better, the pressure in the boiler should always be in a stable state, and the temperature in the boiler should be controlled. Therefore, at any time to monitor and monitor the discovery of any changes should be made certain adjustments. And condensing boiler manufacturers emphasize that the gas in the pipe network should be discharged from time to time, which can prevent vaporization well, at the same time, it should be carried out regularly and the quantity of water in the pipe network should be reasonably distributed.
3, to control the pressure in the boiler well, if the pressure inside the boiler suddenly rises very high during the use of the fully premixed aluminum condensing boiler, it should be immediately found out the cause, usually because the water temperature is too high for gasification. Therefore, the water temperature should be properly lowered to solve this problem. It is also possible that clogging occurs because the dirt in it has not been cleaned up, so the cleanup should be done in a timely manner. If, however, the pressure of the condensing boiler is suddenly reduced, the boiler should be rehydrated in a timely manner, as this is mainly due to the shortage of water.
Recently, Jilin Province Shuangliao municipal authorities about illegal sewage and coal-fired boilers, industrial furnaces remediation work held a mobilization meeting.
Stressed the meeting, do a good job on illegal sewage and coal-fired boilers, industrial furnaces rectification work is to implement the central, provincial party committee decisions need to be deployed, is the need to lay a tough fight to win control of pollution is an urgent need for the construction of ecological civilization shuangliao , is fully successful completion of all levels of environmental inspectors "looking back" need feedback rectification work. Must always adhere to the concept of green development, environmental protection as an intrinsic factor in economic development, internal driving force, implement the most strict system, the most stringent rule of law, provide a strong guarantee for ecological construction.
Meanwhile, the meeting also called for, to understand the situation, address the gap, and enhance the sense of urgency, a sense of responsibility, strengthening conscious selves, issue-oriented, problem remediation ton output capacity determination to do a good job, rectification, lay the winning pollution prevention tough fight; to strengthen measures to intensify its efforts to promote detailed work task decomposition, do a good job related information in archives, a good grasp of time node, to ensure the completion of various tasks by time nodes; to strengthen departmental interaction, resolutely carry ecology political responsibility for environmental protection, and make concerted efforts, up and down, "a game of chess," the formation of remediation work together effectively to the work realistically catch fine catch results.
At the meeting, he conveyed the "Opinions on rectification of illegal sewage behavior" and "coal-fired boilers and industrial furnaces comprehensive improvement plan", and the related issues note highlights.
Another main reason is the corrosion of boiler scale corrosion. For example, he said, kettle to boil water with us daily, if used for a long time, there will be internal kettle scale, first of all affect the quality of drinking water, followed by a pot of boiling water will take longer. Boiler hundreds of times as large than the kettle "monster", if corrosion occurs, that harm is very large.
