Agent 8t Diesel Boiler Latvia

Boiler Water Shortage Accidents szs water analysis 1, the low water level alarm and interlock protection device is not put into use and failure is the leading cause of the agent 8t diesel boiler latvia with a flue gas temperature alarm devices and low water level alarm and low water level chain protection. Prior to the incident, said the fireman did not know the level of low water level alarm and interlock protection device has failed. Only because of the economizer outlet flue gas temperature exceeds its limit emerging (designed for 150 ℃), resulting in constantly ringing alarm bells. Fireman turned off the alarm, low water level chain protection device is also close together. Incident, fireman not effectively remind the water, the boiler continues to operate in the case of water, until the drum from collapsing, cracking convection tube squib. Therefore, the low water level alarm and interlock protection device is not put into use and failure is the primary cause. 2, fireman staff is not strong sense of responsibility and lack of experience is a secondary reason for not timely fireman check the health of the boiler, the water level of the false appearance also have not been ascertain. Even if the water level remains normal, but with fireman experience, should determine the average time in Sheung Shui and take appropriate screening measures, so that when the value is less than the fireman experience or did not do to duty. If you regularly observed from the observation hole to the boiler, you can discover the colors and deformation heating surface, and to take action if the boiler severe water shortages. Flue gas temperature alarm occurs first, without making fireman ascertain the cause, any breach of the rules is closed. Moreover, since a long time to eat off-site procedures are also not shift, so this is the responsibility fireman accident. 3, poor management, poor leadership and management is another secondary cause 1) as companies focus only on the production of steam consumption usually very strict, while ignoring safety management, there is no factory fireman personnel safety training. 2) The enterprise security managers no security certificate management, and knowledge of low water level and low water temperature alarm and smoke interlock protection device is not put into use, nor hamper it. 3) flue gas temperature alarm limit adjustment protracted problem, which is not as competent leadership and a great relationship. 4) boiler room management system, check system is not perfect, no preventive maintenance program, so that long-term drain valve leakage state; while the setting of boiler maintenance system, but not implemented, resulting in low water level alarm and interlock protection device is in low water failure state.

Second, the treatment of agent 8t diesel boiler latvia safety valve trouble

1, when the safety door normally not automatically start, immediately forced open the security door, the door is opened to exhaust air, while reducing the thermal load of the boiler, reducing the steam pressure;

2, when the back seat is not safe door function, should be forced back seat, if the seat back mandatory security gate pulse invalid pulse should exhaust valve closing, so the seat back;

3, when all the safety door failure or serious over-pressure boiler, the boiler should be stopped immediately, can not continue to run down;

1. 130ton cfb agent 8t diesel boiler latvia in Mongolia

2. Coal fired hot water boiler in Mongolia

2019, Shaanxi Province, continue to increase efforts to control and eliminate coal-fired facilities, recently issued a "coal for management action plan Guanzhong area", planned before the end of 2019, the completion of the Guanzhong area of ​​all 35 tons of steam coal-fired agent 8t diesel boiler latvias (more than 20 tons of steam and the transformation has been completed with the exception of ultra-low emission) demolition of all or implementation of clean energy transformation. In accordance with the principle of gas will change, the implementation of clean coal prior to transformation Area off central heating station.

1, to promote the efficient and economical coal to electricity. Cities, counties, the district government to connect with the local power grid companies to develop the Rebuilding embodiment, each village and household investigation and electricity facilities, good co-ordination transformers, distribution lines, smart meters and other distribution facilities renovation work, comprehensively promote the upgrading of rural power grids to meet people's demand for electricity for heating. The end of December 2019, Guanzhong Plain, basically should be changed to make change, the mountains and strive to complete the transformation of the whole village contiguous 60%, the rest of the region before the end of 2020 to complete the transformation. It has completed the transformation to strengthen regional security and stability of power supply and electric heating facility security management. Encourage public bodies to give priority to use high efficiency air source heat pump, storage electric heating and other products.

2, and steadily push forward coal to gas. Gas will adhere to the reform, on the basis of strict implementation of the contract on the amount of resources, natural gas pipe network coverage area of ​​priority implementation of coal to gas. Accelerate the construction of infrastructure such as natural gas pipeline network, expanding coverage of natural gas. In accordance with the principle of special matter, to speed up the preparatory work for the pipe network, gas station facility construction land, planning permission and so on, to simplify examination and approval procedures, to speed up the examination and approval, and actively support the gas company to promote the project implementation plan. Encourage and support the network does not cover the better the basic conditions of township (town, street) using a skid mounted LNG and compressed natural gas. An annual increase of gas from coal to gas priority for rural residents and incorporated into the contract management to ensure stable gas heating. To ensure energy conservation, the indoor installed gas boiler energy efficiency of not less than level 2. According to Mopai base number, speed up the development of sub-annual indeed given village households from coal to gas embodiment, reasonably determine the 2019, 2020 annual scale coal to gas.

3, increase geothermal and other renewable energy heating efforts. Geothermal resources better urban plains of Xi'an, Xianyang City and other urban and rural interface, focusing on rural construction area of ​​more than 20,000 square meters of new residential, with technical and economic feasibility of using geothermal heating premise should be encouraged to have the condition the old district were geothermal heating transformation. Urban construction must be carried out as a heat source point in principle new waste incineration plant. Encourage and support the strength of the research institutes and enterprises to strengthen the solar thermal, biomass energy technology research and development, improve systems integration. Township (town, street) party and government institutions, enterprises and railways, roads and other auxiliary services take the lead in building a number of sites for renewable energy heating demonstration projects.

4, to promote the use of clean coal. Will not have the clean energy alternative conditions and mountainous areas will not have the coal to electricity, coal to gas to actively promote clean coal. In accordance with reasonable layout, standardized management requirements, improve the construction of clean coal distribution centers, to achieve full coverage of clean coal. Distribution center to establish and improve coal quality inspection and sales ledger system, in line with the sales of clean coal, "coal quality coal for civilian goods" (GB34169-2017) and "civil coal coal quality goods" (GB34170-2017) technical requirements, city , loose coal and coal county built-up areas and its surrounding area used to reach No. 1 product technical requirements, other areas prohibit the sale, use more than 1% sulfur, ash content higher than 16% of civil bulk coal, the information contained the bulk coal management online platform, to achieve dynamic monitoring information. Strengthen commercial coal sales, circulation of coal quality control, increase sampling efforts to achieve full coverage of monthly sampling to crack down on the use of inferior coal for sales behavior. Study and perfect the counties (cities, districts) financial subsidies to support clean coal policy, and actively promote the use of clean coal, to ensure that people warm winter.

5, continue to carry out comprehensive improvement of coal-fired boilers. Increase the small coal-fired boilers and furnaces tea, operating the stove, grain storage and drying equipment and other efforts to eliminate coal-fired facilities. Before the end of 2019, the Guanzhong area of ​​all 35 tons of steam coal-fired boilers (20 tons of steam and above with the exception of ultra-low emission renovation has been completed) all removed or implementation of clean energy transformation. In accordance with the principle of gas will change, the implementation of clean coal prior to transformation Area off central heating station.
