Some of the existing in-plant equipment will be retrofitted, modifications made in auxiliary equipment/components and major overhauls undertaken. As boiler is the most important component of a coal-fired power plant, the existing oil-fired boilers at Jamshoro will be replaced with 1x400MW supercritical coal-fired steam generator for drying machine at a cost of $740 million.

The steam generated by the boiler is generally measured in tonnage, but the steam turbine power generation is calculated by heat, and the two can be converted: generator electric power MW = boiler tonnage × steam per ton × steam turbine efficiency × generator efficiency. The steam enthalpy depends on the parameters of the steam. The pressure and temperature of the steam are different, and the enthalpy value is also different. It is generally considered to be 0.7. The coefficient of steam turbine efficiency and generator efficiency depends on the power station unit system.

China is the large number of small coal fired boilers, this part of the boiler unit is particularly suitable for the use of straw fuel fired , there are several reasons:

1.Biomass own characteristics, such as low density, to collect raw material, transport and storage has brought great difficulties, according to the level of tariffs in different regions, the general raw material transport over 50 km or more, its economic competitiveness will be substantially reduced, even though they have adopted the compression molding technique .

2.China's current majority of small coal-fired units desulfurization equipment is not installed, this part of the unit coal consumption is not only large, but also the level of SO2 and dust emissions are also much higher than the fire power units, even superior environmental performance of circulating fluidized bed boiler units, because of cost considerations, most of the circulating fluidized bed boiler unit of limestone system is not put into operation. Therefore, the use of existing small units burning low sulfur, low ash biomass fuels, substitution of coal, coal used for savings and efficient, the installation of desulphurization equipment fire power units, which alleviate pressure on the environment is very beneficial .

3.More importantly, the circulating fluidized bed boiler fuel for its wide adaptability, fuel for co-firing biomass basic need to make any changes, but also to bring the combustion efficiency, reduce emissions and slow down wear a wide range of benefits. This may make small generator / heating circulating fluidized bed boiler unit occupies an important position in the future utilization of biomass resources.

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.
