"Module", equivalent to a single large boiler split into several small boilers, in the number of "simple parallel combination" may be implemented in different tons of steam demand. Modular design structure determines the three characteristics of the boiler. 1, each boiler backup each other upon a single fault occurs in the boiler, the boiler can start immediately the other, a very small effect on the heating. 2, capacity scalability is good, a lot of demand for heating office buildings and other heat load life will change in different seasons, the selection module boiler can be the perfect solution to this situation, at any time by increasing or decreasing the number of boiler units, achieved a smaller investment meet the demand. 3, boiler room infrastructure do not ask, can significantly reduce capital investment costs.

Recently, Jinan City, Shandong Province People's Government issued and implemented the "2018 Beijing and Tianjin and the surrounding regions - 2019 autumn and winter tackling air pollution comprehensive management action plan" to inform the implementation of the program, requires the consolidation of ambient air quality improvement achievements, promote air quality continues to improve. On October 1, 2018 to March 31, March 2019, and all the city county fine particulate matter (of PM2.5) mean concentrations fell more than 2%, severe pollution and over several days up declining.

"Implementation plan" will be based on four construction industry, energy, transport and land use optimization adjustments to promote clean heating, public transferrin, enterprises mentioned standard upgrade, dust remediation, focusing on the consolidation of "scattered pollution" enterprise comprehensive rectification results, ruthless grasping diesel trucks, industrial furnaces and rectification of volatile organic compounds, heavy pollution to the implementation of the weather in autumn and winter peak load shifting production to strengthen joint prevention and control among regions, strengthen law enforcement supervision.

1, continued implementation of the total coal consumption control, strict implementation of national, provincial coal consumption reduction of about alternative work arrangements, and the development of alternatives seriously implement the Jinan City, the work reduction of coal consumption, coal consumption control tasks break down into individual counties, total coal consumption to achieve a steady decline. 2018, the city's total coal consumption control in less than 17.14 million tons.

2, effectively promote clean heating to the town (street) or the county as a unit as a whole. As of 2020, the city's pre-season heating living and improve the basic motivation for heating coal for alternative tasks, to develop a three-year implementation program to determine the annual task of governance. Taking into account the agricultural greenhouses, animal building bulk coal governance and to proceed with energy-saving buildings to improve energy efficiency. The county should proceed from reality, according to local conditions, reasonably determine the transformation of technical route, should the electric power, gas should the gas, the coal should be coal, should be hot is hot, and actively promote the use of solar thermal and centralized biomass utilization; adhere to highlight focus, give priority to urban life and motivation for heating gas demand, priority to promoting the urban bulk coal cleared. Gas will adhere to the reform, to change the electric set, on the basis of priority to the protection of residents in 2017 has started "coal to gas," "coal to electricity" project on gas electricity, gas and new year according to the actual supply and heating period the ability to reasonably determine the residents' coal to gas, "" coal to electricity "households; insist on legislation after the break, substitution of gas for coal to electricity instead of coal and other alternatives, in the implementation of air power is not the case, the original heating facilities will not be removed. In accordance with national, provincial requirements, to complete the clean winter heating construction tasks 33000.

3, complete replacement of the bulk coal areas to be designated as high-pollution fuel combustion zone ban in accordance with the provisions, shall not be burning coal for use again. Severely crack down on sales of low quality coal combustion, to ensure the quality of coal used in line with national and local coal quality standards.

5. Substantial regulatory challenges in securing grid connection and electricity payments

The biomass fuel characteristics play a major role in horizontalboiler technology selection. Parameters of particular importance are the moisture content, particle size, the ash melting temperature and the presence of corrosive elements such as chlorine or sulphur.

Why there will be gas-fired boiler drum wall temperature difference between the upper and lower walls of the upper and lower gas boiler drum boiler temperature difference will cause some damage to the wall of the drum by the compressive stress, tensile stress at the wall by the stress reaches a certain extent gas boiler drum damage occurs even crack. Why would the temperature difference between such a phenomenon? That is because the initial ignition gas boiler drum upper and lower walls will have a certain degree of temperature difference, it is because the initial heating gas boiler, a low metal vapor drum wall temperature, the wall surface of the steam condensation occurs on heat drum, the drum wall in contact with water in contact with the water also occur on the lower wall surface of the heat, but due to the exothermic coefficient of water vapor condensation than the larger, upper drum wall endotherm, therefore the gas temperature of the boiler drum arm is higher than that under the wall faster. This requires us to run gas boiler run time to pay attention to some issues, so as to avoid damage to the gas boiler, ensure the normal operation of the gas boiler.
