coal fired automatic boiler

First, to improve the fuel will be coal into gas in principle, more in line with the relevant environmental standards, coal as fuel for the coal fired automatic boiler has been subject to the authorities to stop, that there is often a company will be coal-fired boilers on the boiler rehabilitation programs into gas boiler embodiment, may use natural gas or alcohol as a fuel after passing through this transformation, the raw coal to reduce all kinds of pollution caused by the fuel, thus using not only environmentally friendly but also improvement in the fuel cost. Second, improve coal-fired furnace boiler furnace to transform into a blast furnace gas fired boiler is the use of auxiliary heating furnace, and then to improve the use of gas for heating, if not exactly when or poor fuel atomization in the combustion furnace gas gathering or tail, it is very prone to catch fire or explode, then the need for means to improve the furnace blast doors, while adding automation and control ignition and flame failure protection devices to ensure safe operation of the furnace process. Third, improve the pre-attached devices did not improve during the coal-fired furnace operation requires a lot of ancillary equipment to carry out normal operations, ancillary equipment commonly used in general including the coal, Cleaner, dust collector and grate and so on, after adoption of these boiler ancillary equipment gas furnaces do not need to use so that you can save and invest more of boiler equipment. Fourth, improve environmental protection degree We all know that coal-fired furnace has been impermissible environmental policy, coal is a serious source of pollution not only pollutes the environment but also cause a variety of effects on the body, after making use of the boiler gas furnace, greatly reducing soot and various soot emissions can effectively improve air quality, more environmentally better protect the cleanliness of the air, but also more in line with the standards of environment protection and energy policy.

Many office buildings are built in the city center area, with increasingly stringent emission standards of air pollution in many cities have implemented ban on coal or Ultra Low NOx emission requirements. Fast production of gas side by using a wing heat coal fired automatic boiler module technology patented technology, NOx emissions as low as 18 mg / m, to meet the emission standards in all regions of the boiler.

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.

Henan district heating gas coal fired automatic boiler heating characteristics and uses of a cell or several cells share one building gas boiler room heating using the secondary heating network, an intermediate heat transfer station, the larger the size of the external heating network. Heating area up to several million square meters of high-altitude emissions fumes. 1, Henan area gas boiler heating system to the Characteristics of A, using the advantages: gas boiler Henan province invested more decentralized heating, can achieve centralized management, easy maintenance and users can achieve high-altitude emissions of pollutants. Coal to gas project, you can use direct existing heating systems and boiler room ancillary equipment, saving the initial investment. B, there is a drawback: the thermal efficiency is relatively low, and heat transfer stations outside the network heat losses and the heat medium conveyance power consumption, high emissions of pollutants, the system adjustment is not flexible, large investment outside the network, does not solve the problem of direct measurement of the heat. In the beginning of the construction of the system utilization is low. The end of central heating systems without measurement and adjustment means. Flat Rate according to heating area. Hydraulic imbalance caused by high temperature heating part of the user, when the room is overheated, the user typically using cooling method fenestration adjust the room temperature, resulting in 8% to 15% of the heat loss. Particularly in the construction of mixed use of different nature, according to the same level of heating, because no means of regulation, office buildings, schools and other heating at night and holidays, the hotel was no usual heating, waste of energy. 2, Henan gas boiler gas consumption due to heat loss outside the network is greater than the dispersion of Henan gas boiler heating, the heating temperature is higher than the average gas boiler single-family household heating Henan, Beijing heating in the gas consumption index 10-14m3 / m2. Gas consumption is mainly due to heat loss and heat transfer stations outside the network than other reasons for the high two ways, hydraulic imbalance serious nature of the use of different architectural mix caused by heating. 3, the heating system uses the ground region Henan gas boiler pollutant concentration requirements more stringent, while heating the dispersion concentration of pollutants discharged warm floor exceeded, central heating may be employed. However, there are requirements for stack height shall be determined through calculation. Rarely used in Europe and North America gas central heating boiler area, or are generally thermoelectric cooling and power generation.
