Gas hot water fire tube boiler in between 40 sec auxiliary burner systems that part of the problem Q: In the process of selection of gas hot water boiler, burner selected is the most important part, because it involves running late effects of boiler, then the burner What the system structure and control principle is? burner control logic is like? 1. What system structure and control principle of the burner is? burner is a fuel and air mixture discharged in some manner (mixing or discharging) combustion means collectively. According to his works, the burner can be defined as a substance by a chemical reaction of the combustion of an apparatus embodiment of the conversion of thermal energy. (Premixed fuel and air mixing means appropriate proportions to full combustion).

Low nitrogen fire tube boiler in between 40 sec revolution to lead the industry in fact so much importance to the APEC summit in nitrogen oxide emissions from the boiler is not accidental. Nitrogen oxide emissions into the atmosphere dissolved in water will generate nitric acid rain, caused extensive harm to the environment, causing huge losses to the economy. For the boiler, fuel combustion is the main part of the nitrogen oxides generated. However, in most cities, nitrogen oxide emissions from the boiler still remain at a high level, or simply just to reach deeper coal to gas demand, low nitrogen, low dust and other environmental requirements far not on the agenda.

1, the number of gas fire tube boiler in between 40 sec blowdown not too much, to avoid excessive heat loss;

2, during boiler operation, the proposed transfer large, transfer a small load operation, shutdown is not recommended to start continuous operation and the like;

3, fireman to be noted that the boiler water quality monitoring, timely replacement of the resin, the effect to ensure the operation of the boiler;

4, pay attention to the monitoring of flue gas temperature, flue gas temperature is too high will take away a lot of heat, wasting nor environmentally friendly.

Recommend siting the fire tube boiler in between 40 sec room and the location of the cell site visit in accordance with the relevant provisions of the above-mentioned gas boiler room design, only the lawn area above the garage of imports in line with site conditions. 1. Since underground garage height is limited, coupled with the explosion vent port without reasonable position, can not meet the specifications of the boiler installation, boiler room should be considered semi-underground structure, i.e., the building height of 2 meters above the top layer in the garage, according to the total height of the boiler room 5 m design. 2. Semi-basement boiler room structure is met by installing the boiler, also addresses the regulatory requirements of explosion-proof explosion venting port, ensure safe and efficient operation of the boiler room. 3. supporting auxiliary boiler, circulation pump house, water treatment facilities have been installed in the negative layer. For abutting against the original return pipe line system. 4. The second heat exchanger unit to be installed in the basement area, respectively.
