Fast dzl series industrial 2 tons coal fired boiler has been to uphold the "mold character, and create boutique" business philosophy, after learning of the status of the state forest mountain elementary school, we are non-stop, quickly prepare a large number of teaching supplies, to the mountains in order to improve children's education hardware conditions positive contribution. In order for children to drink purified water clean and sanitary, after the group discussion after deliberation, determined to provide six sets of water purification equipment and pipeline machine. Teachers and students by means of this device can drink safe water purification, we can say that they know how these "water" next to the Red Flag Canal precious. Watching the children line up smiling face after the contact of water, we all feel distressed bursts.
According to this feature, the blower must be segmented to meet the needs of the combustion. Although the current domestic production of dzl series industrial 2 tons coal fired boilers are taken into account this feature, using the sub-air room, and is equipped with a damper. However, according to the survey, many units in the actual operation is not performed in accordance with the combustion characteristics of air volume control, the amount of air required for combustion and an actual amount of supply air does not fit very well, so that incomplete combustion loss increases. Therefore, adjustment the combustion in the boiler, the air amount to be supplied to the combustion timely adjusted according to need, to reduce heat loss and improve the thermal efficiency. 3. The use of secondary air. Strengthening of the combustion secondary air stream is very effective, it has the following effects: (1) strengthening the furnace turbulence and mixing of the gas stream in the furnace oxygen and fuel gas are uniformly mixed, so that the chemical loss of incomplete combustion and furnace excess air coefficient is decreased. (2) the secondary air vortex formed in the furnace flue gas, on the one hand to extend the suspension of fine coal particles travel in the furnace increases the residence time of the suspension of fine particles in the furnace, so that there is sufficient time than combustion, incomplete combustion to reduce heat loss; on the other hand due to the separation effect of the vortex gas flow, the coal particles and ash particles thrown back to the furnace, reducing the amount of fly ash escaping the mechanical incomplete combustion to reduce heat loss. (3) the high temperature secondary air in the furnace flue gas is improved fullness, that eliminates dead reduced stagnation zone and improve the utilization of the furnace heating surface. In addition to the secondary air had a marked effect on energy conservation, but on the smoke and dust is also very effective.
The larger fuel flexibility of CFB power station dzl series industrial 2 tons coal fired boiler in Iraq is applicable for the clients need various choices,which can use biomass,various kinds of coal include hard-to-burn fuels,low-grade fuels and waste.
Impact of vertical steam dzl series industrial 2 tons coal fired boiler efficiency is basically a bunch of the root causes of the country are carrying out high-profile coal to natural gas national movement, using the vertical steam boiler, very large cuts infected micro particles, toxic gases such as nitrogen oxides same time smoke has also been suppressed. Vertical steam boiler efficiency is a measure of critical standards, common look behind a pile of roots of the impact of vertical steam boiler efficiency. After investigation authorities, vertical steam boiler heat loss is probably due to include these two: undesirable heat loss and flue gas emissions than adequate combustion air. Emission reduction in heat loss can be retrofitted aft vertical steam boiler exhaust heat recirculation installation, or use more advanced types of condensing boiler. Combustion air is not sufficiently analyze the problem over the ratio: generally vertical steam boiler burner ejector, causing the air-fuel ratio can not maneuver scheduling. Lot of non-vertical steam boiler with automatic blower burner, leading to undesirable air-fuel ratio has the following several roots: air-fuel ratio does not contain points over about two cases: when oxygen is in excess, the excess cold air will have unlimited the effect of heat, resulting in increased operating costs vertical steam boiler, low vertical steam boiler efficiency; when oxygen is insufficient, will have insufficient incineration conditions, to produce low vertical steam boiler efficiency.
