Product Description:

The waste heat boiler of biogas generator set is a specialized and efficient energy-saving product designed specifically for the recovery of waste heat from flue gas of biogas generator set. By using threaded tubes to enhance heat transfer elements and expand the heating surface, the heating surface on the smoke side of the water pipe is greatly increased. At the same time, strong turbulence is formed when the flue gas flows through the surface of the threaded tube, which improves the heat transfer efficiency of the waste heat boiler of the biogas generator set and reduces the accumulation of soot. The waste heat recovery device of biogas generator set has the advantages of simple structure, high thermal efficiency, long operating life, safety and reliability, and easy maintenance. The waste heat boiler utilizes the exhaust gas from the biogas generator set to be introduced into the boiler for heat exchange, producing hot water that can be used for heating the biogas digester. At present, hundreds of biogas power generation units have been applied, all of which have achieved considerable economic benefits.

Product features:

1. The evaporator adopts a threaded tube structure, which creates strong turbulence in the flue gas and improves the heat transfer coefficient;

2. Using PLC control to achieve automatic water replenishment of the evaporator;

Product advantages:
For natural circulation, there must be sufficient space for steam water separation to ensure steam quality. There are usually manholes and hand holes on the cylinder body for internal inspection of the boiler. The smoke and ash on the heating surface of this type of boiler are easy to clean, and the water side is less prone to scaling due to its lower heat load. The maintenance of this type of boiler is also very convenient.

This natural circulation boiler cylinder is equipped with a water level gauge and water level control system, while the forced circulation is on the steam water separation cylinder. The boiler body is equipped with a safety valve, and for forced circulation, safety valves need to be installed on both the body and the steam water separator. This type of boiler can directly take water samples from the boiler cylinder for inspection.

Threaded pipes are specially processed with threaded threads inside. When flue gas passes through, it rotates, which enhances heat transfer and reduces the heating area of the boiler, thereby reducing its size and weight. In addition, the flow of smoke inside the pipe can have single return and double return paths.

The threaded tube is the main heat exchange component in the entire flue type waste heat boiler. In order to fully recover the exhaust waste heat of the gas generator set and obtain a large steam production, the flow form of the flue gas in the pipe is double return.
