The main results are as follows: (1) the coconut shell fired boiler for industry of heating system of pressurized hot water boiler is pressure-bearing equipment, which has the danger of explosion. The boiler in the heating system of atmospheric hot water boiler does not bear pressure and is always connected with the atmosphere, so the boiler will not explode under any circumstances, and the safety performance is good. (2) the pressurized hot water boiler is full of water, and there is no water level control problem. There is water level control problem in atmospheric pressure hot water boiler. (3) pressure gauges, safety valves and thermometers must be installed for pressurized hot water boilers, because the boiler is always in a full water state, so there is no water level gauge, and there is no water level gauge at the top of the boiler. (3) A pressurized hot water boiler must be equipped with a pressure gauge, a safety valve and a thermometer, because the boiler is always in a full water state. But the atmospheric hot water boiler is only There are water level gauges and thermometers, because the boiler is connected to the atmosphere, the pressure in the boiler is always atmospheric pressure, and there is no danger of explosion, so there is no need to install a safety valve or a pressure gauge. (4) circulating pumps in the heating system of a pressurized hot water boiler. Is the pumping system to return water to the boiler, the general selection of clean water pump. It should not only overcome the circulation resistance of the system, but also maintain a certain pressure of the boiler to ensure that the boiler water does not vaporize at high temperature. The circulating water pump of the heating system of the atmospheric hot water boiler is pumped from the boiler, the pump is the hot water pump, its function is to overcome the system resistance, mainly to overcome the resistance of the return water regulating valve. (5) pressurized hot water boiler Can supply both low-temperature water and high-temperature water. But atmospheric pressure hot water boiler can only supply low temperature water less than 100 ℃.

Recently, we learned that the city of Zhangjiakou Yuxian environment departments to carry out a special investigation of coal-fired coconut shell fired boiler for industrys, coal-fired boilers have complete control of the number of the county, painstaking, and practical coal-fired boiler renovation work to ensure safe and stable environment of the area.

The action focuses on the central heating pipe network has access to the dismantling of coal-fired boiler units, still use coal-fired boiler heating key units of 18 coal quality, coal to electricity station uniform implementation of the 1001 residents of coal-fired heating boilers civilian electric boiler furnace demolition and safe usage, the main city of 39 sets of bath boiler operation of treatment facilities, boiler demolished nine agriculture-related enterprises from coal to gas and gas safety carried out a detailed examination. Unit 4 of the use of substandard coal, the filing be investigated according to law, for gas safety problems 9 agribusiness, notify the county Emergency Management Agency and the territorial towns to regulate the management of its duties, to further prevent security incidents from the source .

Superheater tubes 1 and the explosion accidents, bursting phenomenon superheater tubes (1) discharge steam explosions near or sound superheater. (2) steam flow abnormally decreased, and the flow is not less than the water flow normally. (3) the chamber pressure is reduced or made negative, when the door severe, see the fire and smoke outwardly steam discharge hole. (4) the flue gas temperature after superheaters abnormally decreased or increased temperature difference before and after the flue gas superheater. Severe (5) damage, coconut shell fired boiler for industry steam pressure drop. (6) the exhaust gas temperature decreased significantly, the chimney flue gas into a gray or white color. (7) draft fan load increased, the current increased.

From the point of view of fuel coconut shell fired boiler for industrys, pipeline transportation of natural gas use sealed, users in the use of the boiler, pipes only need to build a good connection, and decommissioning work on and follow the instructions to complete the operation of the boiler, convenient and safe .
