Heating 5001 kg low pressure boilers should pay attention to what is running on coal gasification project, the cost of gas-fired boiler more and more people's attention, which mainly include investment costs and operational costs of the initial equipment. What is the cost? How much concrete include? The initial investment costs including financing costs of gas boiler purchase cost of the equipment purchase cost and construction cost of equipment, as well as gas networks. It should be emphasized that the cost of gas boiler ancillary equipment commonly used to adjust the pressure equipment, measuring equipment and burners, and procurement costs because of different brands vary. Construction costs are a major natural gas pipeline set of so-called gas network tariffs, it refers to co-ordinate government funds charged to gas customers. Due to the huge gas boiler gas consumption, the cost is very large, it has become a key factor in the development of gas-fired boiler users. The key gas boiler heating period operating costs is the cost of gas. The sales price of natural gas in different regions is different. But now, the cost of heating the gas is much higher than the cost of coal-fired heating heating enterprises. To sum up, gas boiler heating costs significantly higher than traditional coal-fired boilers. However, the clean fuel gas boilers, atmospheric environment conducive to the protection of the city, so in the long run, the use of gas-fired boiler heating is more economical.
Fuel gas control step and the blowing process air volume of the total fuel gas steam 5001 kg low pressure boiler steam boiler is achieved by adjusting a liquid coupling scoop blower. Organization fuel gas steam boiler combustion, is to make a, air pressure, air flow of secondary air with the good. Adjusting the amount of primary air should meet it carries the fuel into the furnace ignition of volatile oxygen required, and to maintain a certain speed, and without clogging the fuel discharge pipe of the jet having a certain rigidity. Primary air volume is too large and too small, the wind speed is too high and too low, should be avoided. In addition to adjusting the secondary air of combustion of the fuel should ensure that the oxygen demand, but must maintain a certain wind speed and primary air is mixed with the master time should have a strong stirring and mixing coke penetrate "the Gray" kinetic , which requires the case may be, each layer of the secondary air flow rate, in order to achieve stable combustion and flue gas excess oxygen appropriate destination. Fuel gas steam boiler, secondary air with what is better? Primary air volume air volume of the total share is called the primary air rate. A small air fraction, pulverized coal is heated to at least the heat required for the ignition point, fire faster, but the amount of primary air to satisfy the principle of combustion of volatiles. Secondary air mixed with the primary air time to the right. If it is mixed before ignition, means an increase in the amount of primary air, so that the ignition delay; hypoxia combustion secondary air if mixed will make late after ignition; if secondary air is mixed all at one position, since the secondary air temperature well below flame temperature, the flame temperature decreases, the combustion slows down, causing the fire. Therefore, the secondary air mixed with fuel should be based on the nature of the combustion zone as required timely sent, so that the combustion of oxygen, and will not reduce the flame temperature to ensure complete combustion and ignition stability. One or two wind speed with what is better? Fuel gas steam boiler once the wind speed is high, the fuel gas stream will catch fire in places far away from the burner, the ignition point postponed; once the wind speed is too low, it will cause a blocked ducts, and ignition point is too far forward, the burner will burn , but also easy to coke near the burner.
A number of factors cause the pressure of the heat efficiency of the 5001 kg low pressure boiler module are carrying substantially all parts of the coal gas impressive work, use a large extent, avoided the module boiler fouling contamination, while discharging hazardous gas like nitrogen oxides obtained a clamp. Thermal efficiency is an important measure of the rule module boiler, let us study the cause of a number of factors under the pressure of the thermal efficiency of the boiler module. After inquire about the personnel, boiler heat loss module is mainly produced in the bear on these two: the proportion of full combustion air with smoke emission unreasonable heat loss. Reduce smoke emission install heat loss can be recovered in the flue gas waste heat boiler module terminal fitting, or use more advanced features of FGR boiler. The combustion air fully proportional unreasonable non-compliant analysis: General ejector module boiler burner, causing the air-fuel ratio is no way to maneuver to mobilize. Part of the boiler module using a mechanical blower burner, resulting in unreasonable cause fuel ratio factors are the following: the main air-fuel ratio unreasonable encompass divided into two cases: when oxygen is excessive, the excess will be numerous cold is heated, resulting in increased cost of energy boiler module, the thermal efficiency of the boiler module lowered; when oxygen is non-compliance, will produce incomplete combustion occurs module boiler heat efficiency is lowered.
The "national industrial energy-saving technologies and equipment Recommended List (2018)" key recommendation "premix wing-type vacuum condensing hot water 5001 kg low pressure boiler" There is a beautiful name - Thalia T6, through the rational use of the U-shaped smoke tubular, cross-wing type tube design structure, and heat transfer at the same time meet the thermal requirements, reduced to 33% of the entire area of the boiler can be placed in a small area in the boiler room. At the same time the use of advanced industry premix combustion technology, will reduce nitrogen oxide emissions to 18 mg / cubic meter, well below the most stringent air pollutant emissions of Beijing, Tianjin, Zhengzhou and other cities 30 mg / cubic meter standard.Free Chat
