1, a ban on new or expanded coal-fired thermal power units of fuel oil or coal-fired captive power plant business. A ban on new 35 tons of steam per hour of coal-fired boilers. Not the implementation of clean energy transformation and more than 35 tons of steam coal-fired boilers to complete the transformation of ultra-low emissions or shut down independent choice by the end of 2020.
2, and resolutely shut down environmental protection, energy consumption, safety, less than 300,000 kW coal units of non-compliance, timely decommissioning of units served their time every day, every day to promote the long running units early retirement. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade and exchange, in co-ordination arrangements can save building capacity ultra-low emission coal-fired units.
3, the control total coal consumption, coal consumption in new coal project implementation reduction instead. Out of tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities, residents in the city's urban area with all bulk coal cleared.
4, speed up and clean alternative to coal-fired boiler industry, a comprehensive Mocha under construction, has been built, the proposed cogeneration, district heating project, and accelerating the construction of district heating projects. Accelerate the clean energy transformation of coal-fired boiler, before the end of 2020 to complete the transformation of coal-fired boilers clean energy per hour, 35 tons of steam.
1. Characteristics of gaseous fuel
It is easy to mix with air during combustion, has low smoke loss, high boiler efficiency; less sulfur and ash in fuel, high temperature coking and corrosion on heating surface; high flue gas flow rate, small overall boiler volume, boiler metal consumption Low volume. Direct use does not need to be broken, the operation is quiet; the ash and sulfur content is much lower than coal and oily fuel; the gas body does not produce a large amount of ash to be treated when burning coal; the pollution to the soil is small; The dust is low and the air pollution is small; the main pollutant is the nitrogen oxides produced during combustion. Of course, gaseous fuels have other advantages as well as some disadvantages and the like.
Gas-fired steam 3 ton fired industrial boiler will need to follow those steps: Due to the special nature of dual-use oil and gas boilers, thereby preparing the initial installation and construction from its long-term project to the acceptance stage there will be any problem to pay attention to the need to comply with, what does? Gas-fired steam boiler needs to follow the procedure step by step to complete. In this process, the need to comply with, what does? Boiler installation and construction of oil and gas dual front, first in accordance with the procedures to handle boiler installation approval procedures, pending approval of Quality and Technical Supervision after!
Factors affecting the energy saving heating 3 ton fired industrial boilers What are the reasons 1, strictly control the temperature of the boiler exhaust gas boiler heating some of the heat loss, exha reduce flue gas heat loss is an effective way to achieve energy-saving heating boilers. There is a certain temperature difference between the outdoor air temperature and the exhaust gas temperature. When the outdoor air temperature is lower than the exhaust gas temperature, exhaust heat loss is generated. Accordingly, the heating boiler exhaust gas temperature should be strictly controlled within the controllable range. If the exhaust gas temperature is too high, if the exhaust gas temperature is too low may increa, it will lead directly to the heating boiler running cost increases, which is due to the increased tail heating surface, so that the exhaust gas temperature as low as possible. In the energy saving work boiler should be carried out technical accounting and economic accounting. Accounting based on the dew point of the smoke, the tail heating surface and heat loss due to the consumption of the metal. 2, the carbon content of the slag reduce heating boiler First, the operation of the heating boiler in order to ensure the heating boiler that burns coal, the coal particle size be controlled, full use of coal resources, while achieving the purpose of protecting the environment. Secondly, reasonably boiler operating parameters adjusted to reduce the carbon content of the slag, that the ratio of coal to air is more reasonable and the coal before combustion in the furnace. Furnace temperature is a key factor in the index reflects a lot of energy-saving operation of the boiler. The carbon content of slag is one of them. In order to ensure energy saving heating boilers, efforts should be made to reduce the carbon content in the slag, timely elimination of negative factors affecting the normal combustion boiler. 3, the outer surface of the boiler furnace control temperature of the boiler size of the heat affected second two factors is the temperature of the boiler outer wall. It is also important for the outer wall temperature of the boiler, the influence of the external surface temperature of the boiler heating boiler. Relatively larger exterior wall area, the higher the temperature of the external walls, the greater the amount of heat to the surrounding environment. To reduce the heat radiation loss of a boiler, the boiler must be controlled outer surface of the body temperature. 4, to improve the thermal efficiency of the thermal efficiency of the heating boiler heating boiler is a comprehensive index of energy-saving measures. Improve the thermal efficiency of heating boilers, but also help to improve energy efficiency and heating boilers. Improve operational level boiler operator, control of boiler operating conditions, timely maintenance heating boilers, heating boilers to save energy. 5, timely monitor the operation of heating boilers timely monitoring of the operation of heating boilers, not only improve the operational efficiency of the boiler, environmental protection can not be underestimated. Different boiler room should take different measures, timely monitoring of the operation of heating boilers. Spread the boiler room should be checked by installing equipment, computer monitor should focus boiler room.
Design of an industrial boiler At full capacity a boiler of this size converts 3 000 litres of fuel oil or a corresponding amount of natural gas to thermal or process heat every hour. This would be sufﬁcient to heat more than 2 000 houses. Because of the huge volume of water and the multi-stage lead-through ofOnline chat
