The Fangkuai Group's unique full-operating boiler operation laboratory has an annual operating cost of more than 5 million yuan, which can simulate the operating conditions of various types of boilers under multi-operating environment conditions. The laboratory provides technical tests such as test and inspection, analysis and evaluation, data evaluation, energy saving and environmental protection, and special software from materials to complete equipment, hardware to software, and even complex large systems.
Application of non-pressure boilers in our country is very wide, compared with the pressure boilers with low safety, explosion risks advantage.
Problem analysis of the deformation of the heating surface of the steam boiler 1, the heating surface modification phenomenon a. Waterwall tubes or deformation of the door to see the fire door from the saw, when accompanied by water, can see the red curved water wall tube. B of the horizontal combustion furnace of the boiler, can be seen from the observation hole furnace wall to the fire front side of the deformation. 2. Heating Surface modification of a. Serious boiler water, heating surface of the cooling pot of water had to be thermally deformed. b. poor design structure. The local circulation flow rate is too low, stagnation, that the wall temperature exceeds the allowable temperature deformation. c. Install error, the pressure receiving member is not free to expand. D. substandard quality, thick scale, excessive water residue.
Gas heating boiler start making blast furnace commissioning believe what needs to be done in many northern cities, it has been put on the heating heating company focused on project work. So, before performing gas boiler heating furnace Kai, What provisions do? First, before the operation of gas boiler, the total power to open and start the burner, the burner is to be noted Use of the purge valve when the steam boiler is completely out, then turned off. At the same time, when you start gas boiler, but also pay attention to check the observation hole, manholes, hand holes, flanges and valves for loose everywhere, if there are loose reinforcement in a timely manner; if after the reinforcement process still leakage problems, will be carried out to check the shutdown. Secondly, we must pay attention to the air pressure of the gas boiler. When the air pressure in 0.05-0.1MPa, do not forget to issue replenishment, sewerage, water supply system and check the test device to send weapons; when the pressure rises to 0.1-0.15MPa when the need to gauge the trap cleaning ; when the pressure rose to 0.3MPa, to "fire load / small fire" knob to "fire" to strengthen combustion; when 2/3 gas boiler pressure goes up to the rated pressure, you can begin to warm the pipe and aspirated operation, and at the same time pay attention to slowly open the main steam valve to avoid water hammer phenomenon, resulting in adverse effects. When the gas boiler furnace Kai started running, if the drain valve is completely out of steam when it needs to be shut down; when the drain valve is fully closed, to slow the main steam valve to open fully open state, in rotation copyright, finally "burner control" Turn the knob to "automatic" mode.
