caution before starting of water tube boiler
When many customers buy caution before starting of water tube boilers, the choice of fuel is absolutely a matter of caution. The use of natural gas boilers is widely used in commercial, industrial, residential, and power generation because of its cleanliness and high efficiency. Natural gas boilers have many advantages.
How many tons of steam can reach 1MW power generation capacity?
According to the energy theorem, we can calculate the answer about how many tons of steam can reach 1MW power generation capacity. However, in the operation of the power station boiler, it is difficult to obtain actual values regarding factors such as heat loss. We can get the relationship between the unit's power generation and boiler capacity based on the performance of the boiler, the efficiency of the unit and other parameters.
Horizontal steam caution before starting of water tube boiler Accident Method two: 1, the phenomenon of pipe explosion of a boiler (1) soda can hear the sound of jet when burst pipes, severe obvious explosions. (2) becomes pressurized combustion furnace by the combustion pressure, and ejecting the smoke and steam from the oven door opening and large air leakage at the furnace walls. (3) water flow is not normal, greater than the steam flow. (4) Although increasing water supply, but is often difficult to maintain the water level, steam pressure and reduced. (5) The exhaust gas temperature decreases, the color of white smoke. 6) furnace temperature is lowered, and even fire. 7) draft fan load increased, the current increased. A bottom (8) has a boiler water to flow out, the wet ash hopper ash. 2, the processing squib boiler (1) are not severely leaking tube rupture and can maintain the water level when the accident is not to expand, maintain the operation load can be reduced for a short time, and then start to be standby furnace shutdown. (2) tube rupture when the water level can not be maintained, should an emergency shutdown, but it should not stop the induced draft fan, Boiler Feed should continue to reduce the wall temperature, the accident will not re-expand. (4) if several parallel for the steam boiler, a main steam pipe and the steam should be the parent partition tube boiler accident.
It is understood that in order to successfully promote the transformation and development of traditional coal chemical industry, January 1, 2019, letter to the Office of Henan Province workers released a special action program (hereinafter referred to as the "Program"), to promote pollution prevention campaign of Henan Province, three-year action implementation of the scheme, to speed up the traditional coal chemical industry (ammonia, methanol) industry green transformation, to achieve high-quality development. "Program" details are as follows.
First, the key tasks
1, and strictly control new capacity. Adherence to the red line capacity, traditional coal chemical enterprises prohibit new construction, new capacity expansion projects alone, is strictly prohibited without permission around the building does not meet the requirements of the industrial layout plan of coal chemical project in principle. The province's coal chemical projects and intensive clean-up, but according to the specified time limit has been approved to start construction of the project in principle, to construction, relocation and renovation projects must be upgraded into the base or campus planning. By 2020, the chemical industry out of the fixed bed coal gasifier intermittent exit single set of devices 300,000 tons / year of synthetic ammonia production capacity.
2, increase the relocation and reconstruction efforts. Further promote the densely populated towns of dangerous chemicals production enterprises and urban built-up areas heavily polluting industrial relocation of enterprises, the implementation of an intensive investigation, the establishment of management accounting, according to "a business a policy" during mode classification advance. Priority to promoting the urban area of coal chemical industry relocation, conversion or quit, not in the urban area but not in the business park to gradually move the park, according to the specified execution be discontinued or phased out. Close to exit the business to achieve the "two off three clear" (cut industrial water, electricity, removal of raw materials, products, production equipment), in situ transformation of the company to implement the upgrading of the standard industry benchmark, off-site relocation of enterprises to According to large-scale, modern principles move into the province for involving chemical industry gathering area.
3, Green transformation. Before the end of 2019, coal chemical enterprises fully completed VOCs governance. And comprehensively promote the chemical industry equipment static and dynamic sealing points, storage, handling, waste water systems, unorganized process emissions and non-normal operating conditions and other root causes of remediation. In accordance with national requirements, the timely completion of the coal chemical industry waste discharge permit issued by the work, companies must comply with the behavior of the sewage discharge permit clear conditions, various types of environmental inspection found violations, strictly and severely investigated and dealt with as soon as possible in place.
Second, the organization and implementation
1, roles and responsibilities. Relevant provincial jurisdiction over municipal government on the development of local coal chemical industry restructuring and overall responsibility, strengthen organizational leadership, with local conditions, the development of coal chemical industry restructuring and development program implementation, implementation tasks initiatives. Coal chemical industry is the main responsibility for the implementation of the restructuring and development, to strictly implement the main responsibility for production safety and environmental protection, the implementation of the relocation of the green transformation. Provincial Industry and Information Technology Department, Development and Reform Commission, the ecological environment, the Office of Emergency Management and other provincial departments according to the division of responsibilities, strengthen guidance and improve relevant policies and measures.
2, strictly implement the policy. Comprehensive use of market mechanisms, economic instruments, legal and necessary administrative means to approach, to promote enterprise restructuring and development. Strict implementation of China's industrial policy, strictly enforce the standards of environmental protection, quality, energy consumption, safety and technology. Relocation and reconstruction of urban population centers dangerous chemicals production enterprises and urban built-up area of relocation and reconstruction project focused on heavy polluting industrial enterprises, shall be given support in terms of fiscal policy, tax incentives, financial support, land policies.
3, strengthen supervision and accountability. Strengthen supervision of new capacity alone, without approval of the establishment of Chemical Industry Park, unauthorized implementation does not meet the industrial layout planning requirements of coal chemical projects, in violation of the registration and management of hazardous chemicals and construction projects "three simultaneous" (also designed, constructed, and concurrent use of illegal activities) system, etc., must be severely accountable accountability.
