dzl coal fired steam boiler

What are the indicators of factors affecting the efficiency of the dzl coal fired steam boiler Shandong? State basically in full swing during the move from coal to natural gas, hot water boiler with greatly minus the fine dust contamination, together with nitrogen oxides and other harmful gas emissions have been manipulated. Power is an important goal of measuring target hot water boiler, give you a look behind the cause of a direct impact on several hot water boiler power targets. By examining the relevant departments, and hot water boilers consume more important from these two local: the burning air-fuel ratio unqualified and heat loss. Possible to decrease heat loss can be recycled at the end of the formation of the latent heat of flue gas hot water boiler assembly, or with more kinds of class condensing boiler. Burning fuel ratio unqualified inappropriate Summary: General hot water boiler according ejector incinerator machine, causing air-fuel ratio can not be flexibly adjusted. 70% of the hot water boiler is a mechanical blower according burning machine, leading to substandard fuel ratio has the following several reasons: the more important fuel ratio failure probability can be divided into two types: When oxygen is overrun, there will not be excessive cold air is heat, hot water boiler power lead to the use of improved hot water boiler output target weakened; when oxygen is non-compliant, there will be insufficient burning phenomenon, showing a hot water boiler output target weakened. Shandong gas boiler steam boiler talked about how sewage? (1) inside open blowdown valve; (2) gradually open the blowdown valve external to warm up and sewage pipes; (3) an external switch repeatedly discharge water valve, slow flush pan scale , so that as the scale is discharged; (4) locking the inner blowdown valve, between these two discharge water storage water drain valve; (5) locking the outer blowdown valve, sewage terminated. When the people usually use gas steam boiler, power outage situation is obviously occurs when there is, admittedly now very small probability of occurrence of a power outage, What, then the people can not ignore this kind of situation may occur. The author taught the people, process knowledge this type of situation from occurring. First, after the power outage, the total mass to quickly lock steam boiler gas valve, this kind of boiler is to avoid the effect of leaking. Second, the next step is to lock the main switch valve with various natural gas steam boiler circuit. Third, locking gas steam boiler slag coherent various water discharge valve block, otherwise will probably cause additional problems of a coherent gas steam boiler. Fourth, to lock the various air intake valve deaerator. Fifth, the above outline done, in accordance with the order of daily occurrence to stop using the shutdown to manipulate, and verify that the volume of water in the furnace, gas and other energy corresponding to the description. Power outages may now be able to basically be able to say that very little gas steam generating boiler work, What, then public still can not completely avoid this kind of situation, which also requires manipulation of the masses of standard rules of this kind of situation occurred after carefully , as if such a situation occurs, etc. without question.

How natural gas dzl coal fired steam boiler steam boiler model selection natural gas main type WNS and SZS type Both models can burn natural gas, liquefied petroleum gas, coal gas, coke oven gas, biogas, including steam boilers and hot water boilers, gas concrete how the selection of steam boilers, we take a look. Due to the different sectors of production processes, demand for steam boilers are also different, and therefore, when the gas steam boiler selection, need to have enough knowledge of the production process, in order to make the right selection and design of the boiler. 1, selection of technical parameters: gas comprising steam boiler rated evaporation, rated steam pressure, steam temperature rated, e.g., general pressure chemical production requirements are not too high, the pressure required to produce 10 kg as an example, then the boiler design pressure of 1.25 MPa is necessary to use; 2, ancillary equipment options: supporting auxiliary gas steam boiler main control cabinet, water supply pump, circulation pumps, burners, sub-cylinder, water treatment equipment, energy, a condenser, users can choose according to their own needs and price configuration; with the Earth's atmosphere deteriorating, I believe that we Chinese citizen environmental awareness is still very strong, in order to reduce pollution of the planet, we must first consider how environmentally friendly energy-saving performance, then consider fuel, gas boiler combustible gases, polluting emissions, environmentally friendly energy-saving ideas. Boiler pressures, consider the problems caused by an explosion caused by overpressure, and even carbon dioxide poisoning incidents. In the control of gas-fired boiler operation, select the better it is simple and easy to operate.

The third reason is that the amount of nitrogen oxide released during operation is very small. Most heating equipment such as ordinary boilers need to use coal materials as raw materials when they are in operation. Materials such as coal generally release a large amount of hazardous air-quality substances when burned. The condensing boiler uses the steam produced by natural gas combustion as the raw material when it is in operation, so the nitrogen oxide content released during the operation is much lower than the prescribed standard. The analysis of the reason for the year-by-year increase in the sales of condensing boilers has come to an end for the time being.

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.
