industrial coal boiler

What is the transformation of the principle of low nitrogen industrial coal boiler: In recent years, the state vigorously promote clean air plan, Yajian coal. Whether the use of coal-fired central heating boilers, and rural small coal stove for cooking and heating, are gradually being clean energy alternatives under the relevant policy. Thus, in recent years, sulfur dioxide, dust content in the atmosphere continues to decline. But it is worth noting that more and more use of natural gas, also caused a certain amount of nitrogen oxide pollution.

Today I saw that when the capacity is the same, the furnace of the oil-fired industrial coal boiler is smaller than that of the coal-fired boiler. Why? The specific reasons are as follows: the size of furnace volume, after the boiler capacity is determined, mainly depends on the volume of heat load. The size of the volumetric heat load is mainly determined by the type of fuel. After the fuel enters the furnace, it will take a certain amount of time to burn out. Fuel is usually required to burn out before it leaves the furnace. It is obvious that pulverized coal will burn longer than oil, that is, the flame of coal combustion will be longer than that of oil. In order to ensure the long-term safe operation of the boiler, it is necessary not only to prevent the slagging of the boiler, but also to make the temperature of the flue gas at the furnace outlet begin to change compared with the ash in the flue gas The temperature is 50 ℃ lower than 100 ℃ to prevent slagging at the furnace outlet and subsequent convection heating surfaces. The ash content of coal is more than that of coal-burning furnace, and the flue gas temperature of furnace outlet is 1050 ℃ and 1100 ℃. There is no danger of slagging in the furnace because of the low ash content in the oil, and do not consider the slagging problem of the slag discharge tube at the exit of the furnace, so the smoke temperature at the exit of the furnace can be higher.

At the same time, domestic coal to electric industrial coal boiler company's development is also very good, and its products are also very suitable for the modern concept of social development, so everyone in the choice when space is very large, fast Boiler came to introduce several now the main point advantage domestic coal to electric boiler.

In mid-November, Langfang City, Hebei Province continue to promote coal-fired industrial coal boiler pollution problem, do the atmospheric release 2018 Fourth supervision order, supervision order states: the country, relevant departments directly under the city's control to quickly take a series of measures to prevent and strictly control burning coal boiler pollution problems.

Now is the time winter heating season, but also the critical period of the comprehensive management of air pollution in the autumn and winter season, the coal-fired heating boiler emissions standards are the focus of Langfang City, air pollution prevention and control. To ensure that coal-fired heating to achieve effective control, reduce emissions, minimize the adverse effects on air quality, atmospheric Langfang City Office will join together to focus, determined to win the battle in autumn and winter air pollution of coal-fired boilers.

Steering proposed order, the relevant departments to combine their job requirements for environmental protection, to develop a coal-fired boiler heating energy saving solutions for special work, establish special supervision and inspection mechanism for all heating stations in the main city within the city limits, supervision and guidance heat stand while ensuring a stable discharge standards, to protect people spend a warm winter. Various environmental protection departments will strengthen the tracking and monitoring of emissions of various heating stations, to be serious penalties for excessive emissions of coal-fired boilers, but also will continue to maintain compliance or below the City heating boilers requirements set emission standards for reward and subsidies .
