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.

Small gas steam boiler in the hotel building applications in daily production, how to save energy and reduce the emission of pollutants, reduce costs, increase economic benefits to the business, the real problem is getting attention, and gradually resolved. Shenyang is a hotel accommodation, offices, restaurants, stores in one large commercial buildings, construction area of ​​6 × 104m2. During the heating period, heating systems, domestic hot water steam system, laundry room used by the municipal heat supply network. After the heating period, domestic hot water systems, steam laundry prepared from 2 model white WNS8-1.25-YQ fuel steam boiler (heating of serving as backup boilers) for the steam, steam production of single 8t / h. Steam boiler room to the sub-cylinder (in the basement podium) linear distance is 200m, and specifications for the steam supply pipe DN250mm, Buried employed, the compensator 4 disposed manhole. Based on the actual measured amount of steam on the hotel, and the application of energy-saving small gas steam boiler in the hotel building were discussed. Selection 2 gas steam boiler us 2009 June 7 to July 1 for steam consumption for domestic hot water systems, laundry room were measured. Average pressure of 0.08MPa steam, hot water systems, laundry average daily amount of steam were 7.43,2.43t / d. Two systems together, the maximum amount of steam per unit time and the average amounts were 0.77,0.41t / h. From the measured data, daily 9: 30-11: 30, 15: 30-17: 00 cooking gas peak, the highest air consumption is 19.65m3 / h, the hotel into the household gas pipeline gas supply capacity of 95m3 / h. According to domestic hot water, laundry room two systems unit time summer highest steam consumption is 0.77t / h, should be used in a 1t / h gas steam boiler, its gas consumption is 76m3 / h. In actual use, reasonable arrangements for gas time, can fully meet the demand for gas gas steam boiler. From the above analysis, the steam production of the hotel is much larger than the existing fuel steam boiler steam summer practical usage. According to the measured summer daily expenditure of more than just fuel costs more than 3000 yuan / d. Underground layer may be mounted on a podium 1t / h gas steam boiler, steam lines since all indoors, and therefore low cost pipeline system, and reduce the emission of pollutants, environmental protection efficiency significantly. 3 gas steam boiler room design of the hotel podium underground over 3 floors, including the basement of the original generator set oil storage has been discontinued, construction area of ​​about 60m2, close to the basement exit ramps from the gas pipeline into the family 8m, after transformation, can be used as gas heating boiler room. Gas heating boiler heating system flow shown in Figure 1. Gas heating boiler to be mounted ventilation system, the ventilation normally not less than 6 times / h, accident ventilation of not less than 12 times / h, the amount of exhaust air volume should be slightly larger, so that the boiler room space maintain positive pressure, and the ventilation should be selected proof products. Gas heating boiler to be mounted combustible gas detection and alarm devices, combustible gas detection and alarm device to automatically signal when gas leakage occurs, the emergency shut-off valve closed and to ensure that no further leakage of the combustible gas. Water spray system shall be installed, and the sprinkler system in conjunction with the original. Gas heating boiler in order to prevent water from leaking into the premises are ground floor, the ground should boiler room waterproofing and drainage ditch, the concentrated water discharged to the ground floor drainage system pressure, into the room promptly [1,2 ].

The sinter cooler waste heat recovery boiler is the latest set of power generation technology that through recycling flue gas heat of drop-tail or wind box of sintering machine and sealed section of sintering cooler and waste heat boiler to promote turbogenerator with low parameters to work.

Another technology being incorporated by boiler manufacturers is the gas turbine.When a gas turbine is used, natural gas is fired, and the hot gasses are used to spin a turbine attached to an electrical generator to make electricity.Since there is still available heat in the gas that exhausts from the turbine, it is then sent through a Utility Power HRSG (Heat Recovery Steam Generator).Similar to a watertube boiler, the hot exhaust gasses from the turbine heat water in the tubes of the utility power HRSG and turn it into steam, which is then used to turn a second steam-driven turbine attached to another electrical generator.This technology is called “Combined Cycle Cogeneration”, and is a very efficient use of fuel because the same fuel source is used twice to drive turbines.
