gas fired water tube steam boilers with d type

The design of the boiler room fire interval is how much? Section 13.1.1 boiler fire hazard classification and fire rating should meet the following requirements: a room, boiler production plant belongs to class D, to the fired water tube steam boilers with d type rated evaporation 4t / h, when the hot water boiler rated output is greater than 2.8MW, boiler room building fire resistance rating of not less than two; steam boiler equal to or less than the rated evaporation 4t / h, when the hot water boiler is equal to or less than the rated output 2.8MW, between the boiler building fire resistance rating of not less than three; II. when the inter-tank, and a pump room between the oil heater are class C production plant, its construction fire resistance rating of not less than two, disposed within said room between the auxiliary boiler room, a room should be set apart from other firewall; III. between the gas regulator production plant belonging to Group a, which is not less than two building fire rating, should be provided between the boiler room and the immediate neighborhood regulator firewall spaced boiler room, which doors open outwards and should not be passed directly the boiler room, the ground should not spark floor. Referring again to the provisions of Article 5.2.2 GB50016-2006 "architectural design code for fire protection," according to fire resistance rating.

Some time ago we learned that the Xinxiang City, Henan Province is located in order to further deepen the pollution gas boiler, reducing nitrogen oxide emissions, improving air quality, we launched a "campaign of Xinxiang City, pollution prevention three-year action plan implementation (2018-2020 Year) "(hereinafter referred to as" an embodiment "), as follows.

First, the implementation of the total coal consumption control

As of 2020, the city's coal consumption control at 13.04 million tons, the proportion of energy consumption control in less than 70%. Coal-fired power plants and strengthen the chemical industry, nonferrous metals, building materials and other key industries of coal consumption control, under the premise of protecting the power system security and stable operation of non-fossil energy generation within the city full consumptive, and actively absorb external calls.

Further promote high-pollution fuel combustion zone ban construction. Gradually expand Ⅲ fuels (coal and its products, including clean coal) combustion zone ban range, central heating and complete cleaning of coal bulk region designated as an alternative class Ⅲ high-pollution fuel combustion zone ban. Increase the combustion zone ban supervision, prohibition of bulk coal sales and hoarding, and severely punish violations of the ban management requirements combustion zone, the region has been completed to prevent bulk coal burning complex.

Second, comprehensive remediation coal-fired boilers

Adhere to the "source of governance, a total ban, focused, step forward" principle, and comprehensively promote the elimination of scattered coal-fired boiler (kiln) coal-fired furnaces and other industrial facilities, the renovation work. Before the end of December 2019, basically out of Xinxiang City, the administrative area of ​​35 steam tons / hour and coal-fired boilers, coal-fired boilers essential to retain, to achieve ultra-low emissions must be stabilized.

Third, actively develop renewable energy

Regions and the development of renewable energy, constantly optimize energy consumption structure, and gradually improve the urban proportion of clean energy use, and build a clean energy-based energy security system. By 2020, the proportion of non-fossil fuels in total energy consumption in the city of more than 7%.

Fourth, to enhance the level of natural gas utilization

Good job of marketing system storage capacity for natural gas. And strive to 2020, the proportion of total energy consumption of natural gas accounted for 10%. Strengthen joint cooperation with the West-East pipeline in northern branch and other existing, fully-use planning Sinopec Xinjiang coal gas "new Guangdong and Zhejiang," and so on through the pipeline from the city's strengths to enhance the capacity of natural gas reserves, counties 2020 (city), District of forming at least not less than three days of emergency reserve capacity average daily gas consumption to protect the administrative district, city gas companies and large users uninterruptible form of not less than 5% of its annual gas consumption of the emergency gas storage capacity.

Fifth, the effective promotion of clean heating

Continue to promote clean heating pilot city construction work. City and county built-up areas to development of central heating based, improvement and transformation of the heating pipe network, a substantial increase in the rate of central heating, the first to achieve clean heating rate of 100%.

Sixth, vigorously promote the construction of central heating

Industrial central heating full coverage. Accelerate the integration of industrial parks (industrial parks) existing heat points, to promote the heating pipe network construction, the gradual elimination of the industrial park (industrial parks) central heating blind spots. Existing types of industrial parks and industrial clusters should be implemented cogeneration or Central Heating, industrial enterprises into the central heating, decentralized heating phase out the industrial park to ensure the realization of "a zone a heat source."

Oil-fired boiler safety instructions oil-fired boiler is one of many hot water boiler to one of how to prevent boiler fuel boiler appears to be abnormal use it? First, to ensure the normal operation of the fuel in the boiler feed water quality and quality of qualified soda, to reduce the water wall tube fouling and corrosion, strengthen supervision and boiler water boiler water when found unqualified, should increase the number of times a given row; while the flue gas flow rate control , especially when the flue gas velocity in the corridor, during installation and servicing, should minimize the distance between the wall and the superheater tubes, while the distance between the tubes to uniformly as possible. second, the fuel boost heating boiler carried out in strict accordance with procedures, control the speed boost. were lower header sewage water wall work required to build the water cycle as soon as possible, promptly switched the gun to ensure uniform heating surface is heated to eliminate half of combustion, eliminating thermal excursions. third, do a good job adjusting fuel combustion boiler, the flame deflection preventing, controlling coal fineness noted that, with a reasonable air to prevent coking, reduces thermal excursions, to prevent the tail reburning fuel boiler; boiler steam parameters be closely monitored, and the main indicators of the amount of water evaporation and the like, to prevent pressure Release, full of water, water accident. fourth, strengthening sootblower sootblower and management, serious fouling preventing heating surface, when there is found furnace coking phenomenon, should be increased blowing Gray times, ensuring good water wall heat sink; overheating problem of the presence of long-term heating surface, installation of thermal supervision controlling temperature measuring points; expansion to ensure accurate indication means using oil-fired boiler units must be fully taken into account the safety problems. in the inspection process must be meticulous in place. to ensure the personal safety of the unit.

Jiangsu chemical plant electric fired water tube steam boilers with d type how much the price of electricity in Jiangsu chemical plant steam boiler price how much? For many chemical plants present, many based on the use of gas-based, but for some local chemical plant, the local gas is not rich, natural gas steam boiler can not be used up. So, there are a lot of fast boiler manufacturers to consult electric steam boiler price. Also the choice of electric steam boilers must be to carry out a wide range of contrast. Recently, a chemical plant for consultation need to purchase an electric steam boiler fast boiler, but for specific models and specific tonnage is not very understanding. Therefore, the technical staff want fast boiler for their own chemical enterprises accounting model and price of. Fast boiler technician for the actual situation of the chemical understanding of the resulting data indicates that the chemical plant with a 2-ton electric steam boilers possible. At present, the model of boiler in square fast, priced at 200,000.
