thermal efficiency of a coal fired boiler

What is the transformation of the principle of low nitrogen thermal efficiency of a coal fired 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.

Operating costs of different fuel steam thermal efficiency of a coal fired boiler comparison: Gas: Advantages: clean energy, high thermal efficiency and save costs. Disadvantages: Restricted gas on condition. Generating a cost of about 2.4 tons of steam million (calculated as the price of 3.0 yuan gas / side) fuel: advantages: no pollution, high efficiency, no fuel limitation. Disadvantages: higher operating costs. Produce one ton of steam costs about 594 yuan (fuel prices by 9.0 yuan / kg calculated) electrical heating: advantages: no pollution, no fuel limitation. Disadvantages: is a secondary energy, high operating costs to produce one ton of steam costs about 700 yuan (electricity prices by 1 yuan / kWh). Coal: advantages: low operating costs. Disadvantages: pollution, restrict the use of some areas, the cost of one ton of steam produced is about 150 yuan (coal prices by 1,000 yuan / ton). It works coal, gas steam boiler

At the same time, domestic coal to electric thermal efficiency of a coal fired 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.

As one of Beijing's air pollution emission standards of the most demanding urban, environmental control is very strict. Beijing primary school campus Emerald City as one of the cradles of socialist culture successor, in terms of the quality of students' learning environment is put emphasis on one hundred percent. October 2017, Beijing primary school campus Emerald City with my company, signed a two Thalia T6 series vacuum hot water thermal efficiency of a coal fired boiler for winter heating use.
