gas boiler head mounted temperature transmitter
How to set the height of the boiler head mounted temperature transmitter chimney
The coal fired boiler can be divided into two kinds：vertical boiler and horizontal boiler. And the horizontal boiler is very economic because of its long flue gas flow, slow smoke discharge, high heating efficiency. So it is widely sued in the market. After buying a boiler, it is necessary for them to build a boiler room,in the installation the height of the chimney also need to pay attention. According to the ZG engineer, the chimney height should be accordance with the lowest height of GB13271-2001 stipulation. Only one chimney is allowed in a boiler room. The specific requirements was listed below:
1.When the boiler’s output capacity is more than 1t/h or 0.7MW, a permanent thief hatch and relevant facilities should be setted in compliance with the stipulations of measuring method for smoke and dust of boiler emission, and The determination of particulates and sampling methods of gaseous pollutants emitted from exhaust gas of stationary source.
2. The exit diameter of the chimney should be not lower than the largest load. The smoke flow should not be too fast. when the load of the coal fired boiler is at its lowest level, the velocity of the chimney exit should not lower than 2.5~3m/s.
3. If the chimney heat does not reach the height of the above stipulations, the maximum discharge concentration of the dust,sulfur dioxide, nitric dioxide should be carried out at 50% of the corresponding area and time emissions standard .
WNS is a wet potshell three horizontal fire tube boiler head mounted temperature transmitter return, this structure has three returns, the oil or gas well atomizer air mixed with the combustor, the combustion in the furnace corrugations, into the first chamber after smoke return pipe, a second front steering return pipe smoke box, smoke box after the last to, through the chimney. It different fuel has a strong adaptability, it can burn heavy oil, light oil, natural gas and city gas. Boiler type low cost, high efficiency, security and stability, space-saving, fuel-efficient, low-cost investment to buy fuel; all pull side butt welds, boiler safety, long life, low maintenance costs. Recovery tail with flue gas condensation, can effectively control the flue gas temperature, high thermal efficiency of the boiler. Quick installation structure, the overall performance of the boiler on the basis of high strength steel design, easy installation and transportation, saving space in the boiler room area.
If a single burner extinguishes, there may also be a deviation in the center of the furnace flame, and the air pressure of the extinguished burner may change. If the fuel supply is interrupted, the oil pressure or pressure indication of the extinguished burner may decrease to zero, while the fuel and gas pressure of other operation burners may rise. After the occurrence of the above situation, the boiler head mounted temperature transmitter must be handled in a timely manner to ensure the safety of use.
A few months ago, Shandong Provincial People's Government issued the "Opinions on Further expand domestic demand and promote development of up short board", which refers to: As of 2020, invested 11 million yuan to complete 5.4 million renovation to replace it clean, let 55 % of villages to achieve clean heating.
In the "clean warm winter Shandong Province Planning (2018-2022 years)" is mentioned, in 2020 the provincial average clean heating rate of 70%, of which more than 20 million people in the city basically clean heating full coverage. 2022, the province's clean heating rate of over 80%. Among them, more than the city and county basically clean heating full coverage, the average clean heating in rural areas reached about 75%.
Jinan, Qingdao, Yantai City 3 converts kinetic energy as a province of old and new core area, to take the lead in forming an electrical heating alternatives such as clean coal-fired heating San basic pattern. Should be in accordance with the electrical power, should be renewable energy sources of renewable energy, the principle of the dispersed phase concentration and binding, while the priority of central heating, the positive development of other energy sources for heating air.
