81 large heating boiler construction

In the operation of the gas 81 large heating boiler construction, from business users can improve combustion efficiency and thermal efficiency of the boiler to start to control production costs. There is a critical factor which is sure to choose a powerful boiler manufacturer, to buy a high performance, advanced technology boilers, reducing fuel through the use of gas-fired boiler does not affect the results reached at the premise of lower production the purpose of the cost. The following are recommendations on how to reduce the amount of fuel gas-fired boiler engineer fast boiler given.

1, flue gas condensation heat recovery system: This system is mainly in the exhaust gas with a reduced amount of heat boiler, the boiler itself without affecting the thermal efficiency, reduce gas consumption.

2, climate compensation system: This system is in accordance with the indoor and outdoor temperature changes do adjust, making the overall gas boiler heating, heat release and building consistent, prevention of indoor and outdoor temperature difference is too large.

3, the heating system water balance: heating the average mass of all heat users, using such a system, it is possible to save about 10% of the energy directly.

4, heating centralized control system: according to the number of thermal load required for the boiler installation, and the heat load between the uniform distribution of the gas boiler, so that all boilers to achieve the best state. This aspect of domestic technology is not mature enough, such as the effect you want to be a better use of imported boiler.

Fuel volume adjustment simple mechanical atomization nozzle adjustment range is usually only 10% to 20%. When the 81 large heating boiler construction load changes little, the oil pressure in front of the boiler can be adjusted by changing the oil pressure before the furnace, and the purpose of increasing the oil pressure can be achieved by increasing the oil pressure. When the boiler load changes greatly, the atomization plate with different aperture can be replaced to increase and decrease the fuel injection. When the boiler load changes greatly, neither of the two adjustment methods can adapt to the requirements, so it is necessary to change the fuel injection quantity by increasing and reducing the number of fuel nozzles. The adjustable range of the atomizing nozzle of the return oil machine is relatively large. When the boiler load changes, the return valve opening can be adjusted accordingly to change the return oil quantity. Return oil The larger the quantity, the smaller the injection quantity; on the other hand, the fuel injection quantity increases. In normal operation, the fuel quantity shall not be increased or reduced sharply, so as not to cause the sharp change of combustion, and cause the pressure element to expand and shrink abruptly and damage.

How to distinguish atmospheric pressure hot water 81 large heating boiler construction and hot water boiler in daily life, people often confuse the pressure hot water boilers and pressure hot water boilers, difficult to discern. In fact, some operators in the industry are nothing more than completely clear detail the differences between the two, let alone teach other people how to identify pressure, pressure hot water boiler and point out both their own characteristics. Below, small series will be divided into three o'clock teach you distinguish the difference between the two. First, look at the furnace pressure changes in pressure hot water boiler and the biggest difference is the pressure. Even the low-cost pressure hot water boiler, the furnace pressure hot water is always consistent with the atmospheric pressure does not change as the temperature changes; the contrary, because the system is composed of soda furnace a sealed container and piping components will naturally follow with increasing water temperature changes. See changes in pressure in the furnace is a more intuitive way to distinguish between the two. Second, look at the professional level control problems because the supply pressure hot water boiler is not operating pressure, the pressure in order to achieve operation of the boiler circulating pump inlet and the outlet is connected to suction hot water in the heating boiler to a user, users return pipe and boiler water inlet necklace, equal to the amount of water into the water. Thus, pressure hot water boiler water level control problems still top box connected to an opening in the drum full of water, the water level control problems. The pressure hot water boiler water level control is no problem, which is one of two significant differences. Third, look at the structure of constraints pressure hot water boiler on the structural parameters of the issue, compared with pressure hot water boiler much simpler. Structurally distinct from strictly limited boiler capacity, parameters, mounting position, etc., only reasonable pressure hot water boiler heating surface arrangement, water circulation to ensure reliable basis, little limitation on the structure, can be largely by actual needs of users to design, construction and installation, flexible and convenient. This is the pressure hot water boiler then more and more important reason for the user's favorite move. In summary, the difference between the atmospheric pressure hot water boiler and hot water boiler mainly in furnace pressure changes, whether the water level under control and whether there are structural limitations in three areas. In fact, the difference between the two is far more than that, they are there is a difference in terms of service life, water supply, safety performance, if you carefully study will certainly find many differences, after contrast, I believe it will not hesitate to choose pressure hot water boiler.

Dongguan City, Guangdong Province in phasing out coal-fired 81 large heating boiler constructions to replace the environmental transformation, biomass boilers in industries packaging, leather, clothing, textile and other widely used. However, biomass boilers still present drawbacks: If insufficient biomass combustion, typically generate a lot of dust, nitrogen oxides and other pollutants, improving PM2.5 concentration, air quality.

Dongguan City Atmospheric Office official said that since the Dongguan started Blue Sky Battle since, the city ton output capacity the courage to decisively eliminate those high pollution and high emissions industries and enterprises, won the majority of the masses of people, as well as many businesses family support; many enterprises to actively upgrade and elimination of outdated equipment and production capacity. In the eco-friendly background, out of high pollution equipment is the trend.

Transformation and upgrading of enterprises demand, government support policies have, inside and outside the echo, Dongguan out of biomass boilers into the fast lane. As of January 10, a biomass boiler out of the task of the city within 31 town street in Shilong, South City, the nave, Ma Yong, Hou Jie, stream, Feng Gang, Xie Gang, Chang Ping, Shek Pai, Chashan 11 Towns in the completion of the task of eliminating all living matter within the jurisdiction of the boiler. In addition, Long, Qi Shi, Tangxia, Sha Tin Kau five towns out of the completion of more than 90%, the remaining 15 Towns also have the confidence out of the task in the year 2019.

While out of the biomass boiler, Dongguan City, accelerate the pace of construction of gas pipeline to provide clean energy for the needs of the enterprise.

Atmospheric Office official admits:. "A few years ago, the city lags behind the construction of the gas pipeline, laying of pipe network coverage area of ​​a small number of enterprises in the coal phase-out of high-polluting fuels, the use of biomass boilers as an interim energy supply equipment, there are also often allowed to change the fuel business, steal burning coal. "but now, due to the environmental protection departments to actively coordinate the town street, village (community), industrial areas, and vigorously promote the construction of natural gas pipeline, starting from the source to provide clean energy for businesses, stealing burn the behavior of coal is greatly reduced.

Over the past year, the city has a new natural gas pipeline 256.6 kilometers, 530 companies have security using natural gas. The city urban management department based on the actual distribution of useful gas needs of enterprises to develop business for the city's more than 600 natural gas pipeline construction plan and coordinate the new Austrian, Xinghua, often positive and three gas pipeline company to carry out construction work to ensure that the natural gas pipeline construction project smoothly, so that more companies access to clean energy as soon as possible.

According to statistics, date, Dongguan City gas pipeline or central heating station accessible area of ​​660 biomass boilers, has eliminated 572 units, 41 enterprises have to apply for the boiler out of subsidies.
