Description

TECHNICAL FIELD

[0001] The utility model relates to the field of boiler, especially a fuel oil steam boiler. BACKGROUND

[0002] The fuel oil steam boiler is a commonly used boiler equipment, which mainly uses high-temperature flame generated by fuel oil to heat water entering the boiler to generate steam. The structure mainly includes a boiler body, a combustion chamber and a heat exchange coil. The steam outlet is usually arranged at the top of the boiler body. For details, please refer to the patent with the application number "CN202222990678.1".

[0003] However, the existing fuel oil steam boiler still has some problems. In the later stage of the heating phase, the steam discharge speed is often very fast. The excessive steam flow rate can cause the equipment that needs to use steam to be under pressure and to be severely worn. The existing technology can only adjust the speed of the discharged steam by two methods: adjusting the boiler pressure relief valve or reducing the heating temperature of the combustion chamber. The boiler pressure relief valve can cause energy waste, and it is difficult to control the heating temperature of the combustion chamber because it indirectly affects the steam flow rate. SUMMARY

[0004] The utility model discloses a fuel oil steam boiler, which solves the problem of excessive steam discharge speed in the later stage of heating of the existing fuel oil steam boiler affecting the subsequent use of steam equipment.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme:

[0006] A fuel oil steam boiler, comprising a furnace body, the furnace body comprising a heat exchange cavity and a combustion chamber arranged in sequence from top to bottom, a heat exchange coil is arranged in the heat exchange cavity, a steam outlet is arranged at the top of the heat exchange cavity, a steam main pipe is connected to the steam outlet, a flow slowing branch is uniformly arranged in the middle of the steam main pipe, and a steam guide valve is arranged at the connection between the flow slowing branch and the steam main pipe.

[0007] The flow slowing branch is arranged on the side of the steam main pipe, which can effectively alleviate the pressure of the subsequent steam equipment. When the steam flow rate in the steam main pipe is too fast, the steam in the steam main pipe is guided to the flow slowing branch through the steam guide valve, and then flows back to the steam main pipe after slowing down in the flow slowing branch. This prolongs the steam delivery path and increases the delivery time, naturally alleviating the gas pressure of the subsequent steam equipment, and the flow slowing branch also plays a role in reducing the steam speed.

[0008] As a further optimization of the utility model, a flow slowing cavity is uniformly arranged in the middle of the flow slowing branch.

[0009] The slow-flow chamber has a large area and can play a static pressure role, that is, steam entering the slow-flow chamber can be slowed down.

[0010] As a further optimization of the utility model, the cavity wall of the slow-flow chamber is provided with an electric heating plate.

[0011] The electric heating plate can heat and keep the steam warm, so that the steam will not be cooled down due to the increased distance.

[0012] As a further optimization of the utility model, the slow-flow chamber is further provided with a gas pressure sensing detector, the bottom of the slow-flow chamber is provided with an emergency exhaust port, and the emergency exhaust port is provided with an electromagnetic valve.

[0013] The gas pressure sensing detector can detect the gas pressure in the slow-flow chamber, and when the pressure is detected to be too large, the electromagnetic valve is opened for emergency exhaust.

[0014] As a further optimization of the utility model, the emergency exhaust port is connected with the steam cooling and exhaust mechanism through a pipeline.

[0015] In this way, the discharged steam will not hurt people.

[0016] As a further optimization of the utility model, the steam main pipe and the slow-flow branch are both wrapped with a heat preservation layer.

[0017] The steam in the conveying process can be effectively kept warm.

[0018] Compared with the prior art, the utility model can at least achieve one of the following beneficial effects:

[0019] 1. The slow-flow branch is arranged on the side of the steam main pipe, which can effectively relieve the pressure of the subsequent steam equipment, when the steam flow rate in the steam main pipe is too fast, the steam in the steam main pipe is guided to the slow-flow branch through the steam guiding valve, and then flows back to the steam main pipe after being slowed down in the slow-flow branch, so that the steam conveying path is prolonged, the conveying time is increased, the gas pressure of the subsequent steam equipment is naturally relieved, and the slow-flow branch also plays a steam speed reduction role.

[0020] 2. The slow-flow chamber has a large area and can play a static pressure role, that is, steam entering the slow-flow chamber can be slowed down.

[0021] 3. The electric heating plate can heat and keep the steam warm, so that the steam will not be cooled down due to the increased distance.

[0022] 4. The gas pressure sensing detector can detect the gas pressure in the slow-flow chamber, and when the pressure is detected to be too large, the electromagnetic valve is opened for emergency exhaust.

[0023] 5. The discharged steam will not hurt people. Attached Figure Description
