Abstract: A microwave heating system is provided including a microwave generator, a fluid pipeline having an upstream section and a downstream section, and a waveguide assembly connected to the microwave generator. The waveguide assembly includes a microwave distributor positioned in the fluid pipeline at a junction between the upstream section and the downstream section. The microwave distributor is in substantially straight line alignment with the upstream section proximal to the junction, while the downstream section is in substantially right angle alignment with the upstream section proximal to the junction. The microwave heating system substantially prevents or remediates gas hydrate blockages in the upstream section of the fluid pipeline at extended distances from the microwave generator. The microwave heating system may also simultaneously control a function of a device remotely positioned on the upstream section or power the remote device.
