half ton gas steam generator

CFBC boilers are generally more economical than AFBC boilers for industrial application requiring more than 75 – 100 T/hr of steam. For large units, the taller furnace characteristics of CFBC boilers offers better space utilization, greater fuel particle and sorbent residence time for efficient combustion and SO2 capture, and easier application of staged combustion techniques for NOx control than AFBC half ton steam generators.

Industrial production is inseparable from boilers, emission control of atmospheric pollutants boiler air pollution control in Shanghai to expand and intensify the focus of the project. Currently, Shanghai Industrial boilers alternative clean energy has been completed, nitrogen oxides (NOx) emissions of major pollutants as a boiler, the boiler due mostly low shelf emission source of ambient air near the ground and ozone greater PM2.5 influence, therefore, this release the new standard, the boiler will be low-nitrogen transformation, improve Shanghai air quality, protect people's lives and health and other aspects demand a strong thrust of great significance. Throughout the country, Beijing, Tianjin and other places have started low-nitrogen transformation boilers for low-nitrogen transformation has a more mature technology reserves. Based on the above considerations, for the effective control of NOx emissions from boilers, to further deepen cooperative control of PM2.5 and ozone, according to the standard first, to further accelerate the transformation of governance principles, it is necessary once again to revise the standard boiler.

According to local environmental standards and revision procedures, the Municipal Environmental Protection Bureau held a meeting to hear the relevant departments, enterprises and the opinions and suggestions of experts, and in 2017 August 4 to September 15 in the online open standard full text to solicit public opinion. At the same time the Ministry of Ecology Environment solicit written opinions Municipal Development, City Commission by letter and other related commissioned Bureau, industry organizations and boilers, production units and other enterprises. Municipal Environmental Protection Bureau and the Municipal Quality and Technical Supervision on January 19, 2018 organized the expert technical review meeting, the panel agreed that standards through technical review. Approval by the Municipal Environmental Protection Bureau and the Municipal Quality and Technical Supervision audit report to the municipal government.

The new standard has been revised for several aspects, one is no longer on the "central heating boiler and the nominal amount of evaporation less than 65t / h boiler cogeneration" provisions alone time; the second is to simplify the original class standard boiler merged into " gaseous fuel boiler "and" boilers "categories; are three different degrees of contamination tightened limits particulate matter, sulfur dioxide and nitrogen oxides; four new boiler is implemented from the date of implementation of this standard, the boiler given a transition period of about two years.

New standards for gaseous fuel boiler particulate matter, sulfur dioxide and nitrogen oxides are applied strict limits, but mainly considering the control of nitrogen oxide emissions, and further improve air quality. In the transition period boiler (1 October 2020) to limit nitrogen oxide 150mg / m³; after a transitional period of 50mg / m³. Date of implementation of new boiler nitrogen oxides from standard starting execution 50mg / m³ limit. Taking into account the comprehensive utilization of straw in Shanghai, biomass fuel boilers follows the standards of the original project control and limit requirements.

Select bath boiler approach the winter a lot of people like to go to the bathhouse, many baths are heated using a boiler to heat water, so the choice in the market time to ensure the safety of the equipment, the following give you some selection methods: 1, boiler manufacturers when purchasing ① to see the boiler manufacturing quality manufacturer to see if it has the capacity system, and to be equipped factory data. ② must also examine the manufacturer's after-sales service, because some special furnace, only original components manufacturing units only. 2, a clear understanding of the needs to use to buy their own boiler: heating boilers, boiler drying, eliminating hot boiler, bath boiler or other purposes, different circumstances choose a different furnace. 3, for example, to the clear objectives for a heating boiler, would simply purchase a boiler to steam boilers or hot water, the result of the later unit of a catheter oil boiler, and then the half ton steam generator through the catheter oil converted into steam, converted to hot water heating is a waste of resources, heat transfer effect is not good. Bath boiler is not as boiler home, as it is relatively large and a lot of species, is to make everyone in the choice of its mass on the front, because a lot of people bath in case of failure can result in serious personal loss, so we have to strictly check quality.

Oil-fired boilers include oil-fired water boilers, oil-fired hot water boilers, oil-fired heating boilers, oil-fired bath boilers, oil-fired steam boilers and so on. Oil-fired boilers are boilers fueled by light oil (such as diesel oil, kerosene), heavy oil, residual oil or crude oil. Compared with gas-fired boiler and gas-fired boiler, oil-fired boiler runs more economically than electric heating boiler and is more convenient to use than gas-fired boiler. With the development of economy and social progress as well as the improvement of people's awareness of environmental protection, coal-fired boilers are gradually out of sight because of serious pollution. Instead, they are replaced by new types of environmental protection digital boilers, such as electric heating boilers and oil-fired boilers. Gas fired boilers, etc., electricity Heating boiler operation is the most expensive, gas-fired boiler needs to be opened with gas pipeline, then, if there is no natural gas pipeline, but also hope that the operation cost of the boiler is low, only the choice of fuel-fired boiler. Oil-fired boiler is heated by burners, fuel atomization effect is good, fuel combustion is full, chimney can not see black smoke, so fuel-fired boiler green environmental protection, efficient and energy-saving. After the fuel oil is sprayed into the furnace, it is very easy to mix with air and burn rapidly and exothermic rapidly. Compared with coal-fired boiler with the same parameters and capacity, the thermal strength of furnace volume can be doubled. However, in order to reduce the heat load in the combustor zone, the water wall tube in this zone is avoided. Because of the overtemperature, the furnace volume is only reduced by about 1 / 3. Moreover, because the ash content in fuel oil is very little, it will not be slagging on the convection heating surface, so the flue gas temperature at the furnace outlet can be as high as 1300 ℃, and the pitch between tubes on the convection heating surface can be reduced to increase the flue gas flow rate, thus the heat transfer coefficient on the heating surface can be increased. Save heating area and steel. In order to prevent spontaneous combustion of carbon black oil scale on economizers and air preheaters, steam soot blowers should be added to these parts to keep the heating surfaces clean. At the same time, because the fuel oil does not form coke slag, the membrane water-cooled wall can be used to form a micro-positive pressure (500 x 1000 cow / ml). A boiler. It can save the draft fan, only the fan can exhaust the flue gas out of the furnace. If the whole shell of the boiler is made of thick steel plate, it can also be made into a positive pressure (0.3 ~ 0.6 MPA) boiler, which can make the whole structure of the boiler more compact, and is more used in the gas-steam combined cycle generator set.
